v2.0
Bernoulli — the second generation of Abacus. Every generation keeps what the last one proved and adds only what beat it in replay; Bernoulli is Archimedes with four rules added and one retired, judged the way every change is judged from here on: against buy-and-hold on the same window, return and risk together. Replayed 2019 to today after average trading costs (2 bps a side on a stock, 1 on a fund — included for fairness; costs vary by broker and liquidity), it earns 20.3% a year at 12.9% volatility against the index’s 14.6% at 19.4%, with a worst drawdown of −15.5% against −41.7% and less than half the market exposure. It does not beat the index in every bull year and the desk will not claim it does; the whole table, and the first generation beside it, is on the engine page.
The gate. A run is listed only when the engine’s own read of the name’s longer trend agrees with it — a strength run with the trend behind it, a weakness run with the trend against it. Runs that start against their longer trend tested worse in every tape, so they no longer reach the list. The ‘why isn’t it listed’ answer says whether the trend agrees and by how much.
Shorts against the sector. A weak name is now hedged with its own sector fund, dollar for dollar, at full size — against the index, or on its own, it tested worse. Listed only where the number is positive after the gate: a Flat tape. In a Trending tape the hedged short tests flat, so the desk does not list shorts there — the table on the engine page shows the cell.
Cycle pairs replace leader-vs-laggard pairs. The first book’s drag was the laggard leg; the new pair is built on timing — a fresh riser (Alpha 60–80 and climbing, new that day) against a stale leader (85 or more, no longer rising) in the same sector, sized at equal daily risk, out when either leg’s Alpha closes under 60 or on day 21. Offered in a Grind and a Dislocation, where it tested positive. Leader-vs-laggard pairs stay on the Analysis board; they are no longer a listed trade.
The dislocation bounce. In a Dislocation the desk used to list nothing. It now lists the weakest tenth of each sector over five sessions, long the name against its sector fund, out the close its five-day move is back to zero or on day 5 — the desk’s answer to the snap-back that punishes shorts in a crash. Positive in every dislocation we could replay; offered only there, because outside one it does not clear its costs.
Sectors that earn it. A sector’s runs are listed only where they tested clearly positive over the whole window. Energy and Staples runs are not listed; the sector table on the engine page shows every cell. A name in those sectors can still be opened and hedged by hand.
Seventeen names and one sector join the desk: Materials (XLB) with LIN, APD, SHW, FCX, NEM, NUE, DOW, ECL, ALB and MLM, and in Technology CRDO, ALAB, LRCX, MPWR, CDNS, SNPS and ASML. A wider universe was tested and set aside — breadth on its own made the book worse; selection is part of the edge.
The three-per-sector cap from 1.7 is retired: with the gate and the sector rule in place it cost return without buying stability. Every Bernoulli line is full size.
Generations against the market. The engine page now draws each generation’s rules against buy-and-hold since 2019 — equity on a log scale with drawdowns beneath, and a table of return, volatility, Sharpe, Sortino, worst drawdown, longest underwater, months up, market exposure, steadiness and every year — so the standard every change is held to is on the page, not in a sentence. Every after-costs number on the desk now charges the same average costs — 2 bps a side on a stock, 1 on a fund — stated wherever it applies; they are averages for large-cap names at a commission-free broker, included for fairness, and vary by broker and liquidity. The edge table’s per-trade cells stay before costs.
Your book against the index. Both equity strips on the tracker — yours and the house’s — now carry buy-and-hold over the same sessions as a grey dashed line, rebased where the book’s line starts, with the two end values side by side. The comparison every rule on the desk is judged by, drawn where you judge it.
Since posted, on the row. Every listed trade now shows its own mark since the desk posted it — close to close, the spread for hedged shapes — with the day count beside it, so an eleven-day-old run tells you what it has done before you open it. Your own tracking is still graded from your day.
The verifiable record. The house book now keeps a record that cannot be rewritten: every settled day — what the rules opened, what they closed and why, the day’s mark — is sealed the same evening, and a day’s record is published once its positions have had time to close. Nothing can be edited or added after the fact without it showing, and anyone can check the published record against the seal. The engine page explains how.
Generation notices. Every tracking and every house position carries the generation that posted it and is graded by that generation’s rules until it closes — a trade tracked under Archimedes keeps Archimedes’ exits; nothing is re-graded. The tracker shows the generation on the trade chip, and the house book on the engine page reports its record by generation.
The manual’s Trades chapter is rewritten for the four shapes; the tape chapter says what a dislocation lists now; the returns chapter carries the Bernoulli table; the broker walkthrough has a cycle pair and a bounce. The first generation’s table stays on the engine page, for the record.
The Workshop is complete — all ten lessons. New: what a good strategy feels like (losing streaks inside a winning strategy, and how to size for them); who earned it: alpha and beta (a calculator for any stock’s year, and a scatter you can fit yourself); why exits are rules (a toy market with three exits, and the desk’s replay numbers for each); the summer 2026 case study (the leaders fell 19% while the index rose 3% — day by day, what the rules saw, and what changed because of it); and overriding the rules (four common overrides applied to a thousand desk-shaped trades, and six questions to ask of any track record).
One P&L cell on every tracked row, whatever the shape — the result since you tracked it, close to close, and the dollars on one line at your account settings; the basis sits in the hover. Tracked pairs now show their trade chip and generation too, and the equity strips name the date their comparison with the index starts.

v1.7
Follow the house. Turn it on in Account and every trade the house book takes appears in your tracker at the settle, sized for your account and marked house. Your book becomes the house's trades plus your decisions — skip one, add one, close one early — and the closed view shows what each choice earned or cost against the rule. Nothing is traded for you. The manual's tracker chapter now walks through placing each trade shape at Interactive Brokers, Schwab, Fidelity and Robinhood, exits included.
Why isn't it listed? Type a name under the Trades list and the engine walks its own rules for it — the shape it would be, each rule passed or failed with its value, and what it would take. Every ticket carries the answer as one line. The rules it checks are the ones in the manual; nothing new is revealed, only which one a name fails.
Three long lines per sector. The list and the house book now hold at most three long runs from one sector; the rest fall to the next shape in rank. Replayed 2019 to today on the desk's rules: return up, volatility down, the worst drawdown a fifth smaller and 2022 cut from −6.7% to −2.5% — a rotation is usually a sector rotation, and a book with six longs in one sector eats it whole.
The Workshop. A new place, separate from the manual, that teaches the thinking rather than the desk: short, level-headed lessons on trading, risk and returns, each with the numbers behind it, something to play with, and what it looks like on TradeMath. The first five — Two 12% strategies, Volatility is a tax, How long underwater, Hit rate is overrated, Size is the dial — are live at trademath.com/workshop; five more follow. Free to everyone.
Returns are not the number. A new manual chapter, open to everyone: return against risk, volatility and drawdown, Sharpe and Sortino in plain words, alpha and beta, why the smaller swing compounds better — with the desk's rules against buy-and-hold as the worked example, including what the desk does not claim.
v1.6
Sized for your account. Set your account size and per-position percentage once, in Account (or the sizing dialog if you are not signed in), and every trade line shows the shares for you — full lines at account × per-position, half lines at half. A leg that rounds below one share turns amber so you never trade a hedge you cannot buy. The Size-it card still lets you try a one-off amount.
Exit alerts, two ways. In Account — now a person icon in the top bar, coloured by tier — turn on email (one message the evening a tracked trade's tested exit fires, after the close is settled, each trade once) and browser (a desktop notification the moment the tracker sees a new exit while the desk is open; your browser asks permission once).
Override cost, both sides. Your book's closed view measures your discretion against the rule three ways — your result minus the house's on the trades you both took, the list trades you skipped and what they did, and what your own off-list picks did — and the house book answers from its side: its result on the shared trades, what it took without you, and today's mark.
The house book reads like yours. Now and closed views, hit rate and profit factor withheld until ten closed (the first to close are the quick losers by construction), and both books end with an equity line — the last sixty sessions, open and closed marked daily, the way a broker draws it.
The path, not then-vs-now. Every tracked row carries a sparkline of its result since entry, one mark per close, thesis-signed — green when paying, red when not — so you can see how a trade got where it is.
The digest is the trade list. The evening email is rebuilt from the Trades tab: the tape and its posture line, the trades posted at today's close — each with the shape's tested number and that name's own last runs, best and worst — your trackings ranked exit · watch · working, and the house book in a line. It sends only when something was posted or one of your trackings changed state; a quiet day sends nothing.
The manual, rewritten. Alpha, True strength, Reading a name and Hedge pairs are rewritten in the plain voice of the Trades chapter — shorter, verb first, each concept tied to where it shows on a trade line — with every tested finding kept and every link unchanged. The Tape chapter opens with what the tape does to the trade list.
v1.51
Abacus, introduced. The engine behind every number on the desk now has its name on the engine page: Abacus — Alpha · Breadth · Attributed · Covariance · Utility · Score — with its first generation, Archimedes, live since the June 10 launch, and what it introduced. Generations are evolutionary: each keeps what the last one proved and adds only what beat it in replay. The next, Bernoulli, is named while in study, with the two questions it takes up.
Your book, two views. Closing your worst losers used to make the book look better, because open trackings dropped out of the math. Now the book has a now view — every open tracking marked from its own entry plus every closed one at its frozen result, equal dollars in each, so the book's P&L is the average trade, with hit rate, profit factor, the open and realised averages, and the single open trade furthest underwater — and a closed view, the realised record the ratios are built on.
The engine page timeline is banded by generation, each with its own tint and the name inset once, so you can read which rules were in force from the shading.
Charts keep score for as long as you hold. The spread lane's holding band now runs from your entry to today, not just to day 21; the tested exit is marked where it first fired — a red dashed line with 'tested exit · Narrowing ×3' (or 'day 21') — the twin of the main chart's exit marker; a name you tracked keeps its verdict tint even with a pair charted on top; and a pair you tracked shows as tracked from either leg, with the since-entry readout signed as your trade.
Jumping to a tracking now lands on the row and flashes it in the row's own colour — red for Exit, amber for Watch, green otherwise — after the scroll arrives, not before.
v1.5
Trades — a new front door. The desk now opens on a short list of fully specified trades the engine has already qualified: the name, the hedge, the exit it was tested with, and full or half size — ten at most, ranked. One number beside each: the average outcome of that shape, in the current tape, at that exit, replayed walk-forward since 2019, with the hit rate, the holding time and the worst one-in-twenty next to it. Shapes whose number is negative in the current tape are not offered. Open a row for the run itself, the run clock, the outcome distribution, the name's own last runs, shares per dollar, and why it qualified in plain words.
The run clock. A run is a temporary state — most end within two weeks — so each trade shows how many runs like it were still above the exit line by day. Runs the engine's checks agree on last about twice as long, in every tape we replayed. The clock says how long, not how much.
Weak names only against the index. A weak name shorted on its own tested poorly; hedged against the index it held up. The desk offers only the hedged version, at half size.
Hedge switch on every long. The line quotes the plain run; open it and switch to the index or the sector hedge, each with its own tested number.
Two books on the tracker. Your book: closed trades, result frozen at the close, with hit rate, profit factor and — after 30 closed — Sharpe and Sortino. The house book: the desk's own record, every qualified trade taken at the close by the rules, sized by the rules, exited by the rules, after costs, marked daily. Trades you track are graded by their own exit: Working · Watch · Exit · Done.
The engine page. trademath.com/edge — where the numbers come from: the full tested table with the red cells shown, the run clock, the house book, and the evolution log of every change to the engine and every finding set aside. Twenty-one studies since launch now have a public home.
The manual opens on the trade line. Start here is rewritten around the front door, with a new chapter on reading a trade — line, detail, books — and the 60-second tour now begins there.
v1.30
The tape now acts on the score — in exactly one place. A bullish read on a Very Extended name while the tape is a grinding bear or a dislocation gets its conviction trimmed (the ticket says so). Replayed against the alternatives: a blanket haircut removed the entries that worked, and trimming stretched names in a Flat tape removed the good ones — only this cohort was reliably bad, about −3% vs the market in three weeks in both 2022 and 2020. Nothing changes in Trending or Flat tapes, for bearish reads, or for pairs.
A dislocation now shows which half you are in — Dislocation · falling or Dislocation · rebounding — on the rail, the board, the ticket and the Pulse. We replayed every dislocation we have data for and the two halves behaved differently, most of all for pairs whose legs are true peers: the rebound is where the weakest names snap back. The posture line is written for each half; the manual chapter has the story.
A cleaner desk — one command bar (brand · Market/Sectors/Stocks · search · tools) with the five market facts as a quiet rail underneath; both stay pinned as you scroll. Each fact's ? opens its manual excerpt. The engine-components checklist reads as a tidy grid.
A way in — a 60-second tour of the desk (five stops, skippable) offered as a small button on Today's edge until you've taken it; brand-new accounts land in it once. The manual is rebuilt as ten chapters, each its own page: Start here (what TradeMath does, where the edge comes from, your first two weeks step by step, with pictures of the desk), Alpha, Cumulative relative performance, Reading a name, Hedge pairs, The tracker, Reading the tape, The market, Signals and the Daily Pulse, and Tested findings — every tested cutout in one place. Old links keep working.
v1.29
The tape — the desk now reads the market's character into one of four states (Trending · Flat · Grinding bear · Dislocation) and tells you, wherever it matters, how ideas tested in that state: the front door, the Hedge Ideas board, the ticket, the bell, and the Daily Pulse. The state changes at most once a day at the close; a 'tape turning' notice flags a hard intraday disagreement as a heads-up. Every mention links to the new manual chapter, Reading the tape, with the twenty-year test results per state
The hedge question, settled across twenty years — we replayed hedged expressions through the 2015–16 flat tape, 2018, the 2020 crash, and the 2022 bear. The manual's note now tells the whole story: hedging a strong name costs return in rising tapes, roughly breaks even in bears, and pays handsomely in crashes — insurance in the strict sense, with far smaller worst-cases everywhere. The two-leg peer basket was the steadiest form in every era
A cleaner top of the desk — the header keeps only search, the bell, the manual, and your account; below it, a sticky desk strip carries the Market · Sectors · Stocks navigation and the five facts worth keeping in view everywhere: session, the tape, the market regime, Market α, and tone
Alpha now shows its day — a tiny range bar beside the score, on the Market α chip and on every stock and sector ticket: today's low-to-high of the score, a tick where it opened, a dot where it sits now. Whether a name's strength built through the session or bled away is one glance, no numbers required (they're on hover)
A tested exit for directional calls — bullish trackings now raise 'Alpha under 60 — tested exit' the day the score closes back below 60, ranked into the tracker's Act tier. In testing it kept most of a run's edge in less than half the time with half the worst-case, and cut losses by two-thirds in the 2022 grind — the directional twin of the pair book's three-Narrowing-days rule. The manual explains, with the numbers
Charts wear the verdict — from the day you tracked a name, the chart's background is green while the call is paying, red while it's losing, amber while it's sideways (thesis-signed: a short that fell reads green). Tracked pairs get the same on the spread lane's band, still brightening through the tested window. And when a bullish call's tested exit fires, a red 'tested exit · α<60' marker shows the exact day
Extension, read through the tape — a new tested note in the manual: 'Very Extended = chase risk' is true in a grinding bear and false in a trending tape, where the already-stretched names carried the edge. Chase strength when the tape trends; look for the discount when it grinds
v1.28
Five more names on the desk — Onto Innovation (ONTO), Akamai (AKAM), Strategy (MSTR), Teradyne (TER), and the New York Times (NYT) join the universe: 150 stocks, fully wired into peers, hedge pairs, earnings, and search from day one
The ticket knows all your angles — the note under Track now lists every tracking that involves the name: directional dates, hedge pairs on either side (▲UNP/DE, FDX/▼UNP), and expressions it anchors or hedges — each a click straight to its tracker row
Straight talk on hedged expressions — a new tested note in the manual: this year, hedged single-name expressions underperformed the plain long (a strong name's sector and peers are strong too — shorting them costs drift). Use Relative when you need the neutrality; if you hedge, the two-leg peer basket measured best
The board stopped repeating itself — held pairs now spend the same diversity budget as fresh ones, so one hot name can no longer snowball across days: it keeps its two best crosses and yields the rest of the strip to other ideas
v1.27
The tracker organizes itself — positions now sort by tested severity into Act (the three-day Narrowing exit fired, or a thesis flipped), Review (earnings today/tomorrow, an outsized spread break, hedge drift, past the tested payoff window, or a gap that converged without paying), and Holding steady. Deadlines rank first within Review, and a quiet tracker stays a plain list — no empty warning tiers to learn to ignore. A converged gap that PAID gets the friendly twin — 'gap converged — paid': the story ended your way; what remains is luck, not thesis
The header counts what matters — 'X need action · Y to review' appears beside the tracked total only when true
Sort it your way — a tracker sort control: Urgency (default), Winners and Losers (move since entry; directional outlooks by thesis-signed Alpha change), Newest, Oldest, A–Z. Repeat trackings of the same thing stay grouped in every mode
The gap breathes — tracked pairs show the Alpha gap then AND now (Δ59 → 50). The Δ's color looks forward (is the thesis still ahead: green intact, amber winding down, red over); the spread beside it looks backward (did it pay) and keeps its own color. Red Δ next to a green spread = story over, but paid. The manual walks all six combinations. Gap chips name your quadrant in words — converged or inverted, paid or unpaid — and chips now obey a hierarchy: one verdict speaks, the plain trend chip yields, so a green chip never argues with an amber one
The tracker's scoreboard — a composite strip on top: winners vs losers with hit rate, average AND median result (the median can't be fooled by one big winner), and your best and worst positions by name, each a click from its chart. Equal-weighted across open trackings from each one's entry — a health snapshot, not a portfolio return
Clear all grew teeth and manners — it's now 'Delete all trackings', set apart from the sort control, red on hover, and it asks before it acts. And an account emptied by mistake heals itself: any signed-in device still holding your list restores it on its next visit
One band instead of two broken lines — a tracked pair's holding now reads as a green band on the spread lane: gentle from your entry, a shade brighter through the tested payoff window, whose edges wear > (day 10) and < (day 21) chevrons. The lane header counts the window while you're inside it: tested window — day 14 of 21
Red means act, not bad — context-aware chip wording: the tested exit on a profitable pair reads 'exit with the win' (the rule's best case), and past-the-window on a winner reads 'protect the gain'. Same rules, same colors, honest mood
A front door — the Market tab now opens with today's read: three cards of the strongest longs, weakest shorts, and best-qualified hedge ideas (widest fresh gaps, true peers favored, heavy market leans penalized), every name one click from its full chart. First visits land here; your last tab is remembered after that
v1.26
Net β on every pair — the hedge readout now leads with the conclusion: the pair's leftover market exposure per $1 long at the shown sizing. Green near zero = a pure relative bet; amber or red = the pair quietly leans long or short the whole market, and the chip says which. On the lane header and board cards as a chip, on the ticket as a Market lean scale (a dot between short-bias and long-bias with the verdict in words) — and frozen into the tracker at entry, since betas drift. Because they drift, the tracker watches: if a pair's net exposure moves well away from your entry into a real lean, the row raises a hedge-drift flag with both numbers. The manual shows how to read it in dollars — and how to cancel it with a small SPY leg, or keep it on purpose
Movement fingerprint — a new Movement row on stock tickets: how much a name moves on a 0–100 scale (translated into a typical daily swing, so 60 reads as about ±2.7% a day), with the bar split into the share the market explains (blue) and the stock's own story (amber). Same score, opposite characters — and the contrast is what makes a good hedge
Tidier ticket — the Hedge idea row's Track button no longer floats free on narrow screens
Cleaner compare — adding a compare symbol now shows its raw price as a dotted purple line and rests the vs-sector line while you compare (it returns when the compare is cleared). Dotted always means price; the color says whose
The manual grew a Market Internals & Alpha Board section — Pulse, Alpha Momentum, Tide & Flow, Trend Posture, and the board's four columns, each in plain words — and ? links now sit on Market Internals, the Alpha Board, and the Outlook Tracker, opening the right passage in place
Tested findings stand out — every measured result in the manual now sits in its own green 'From our testing' cutout, including a new one: a red nβ chip marked front-loaded pairs in our replays (strong early, weakest by a month) — a pair-quality caution, not a hedging to-do
v1.25
Spread shock on tracked pairs — an outsized single-day break against a tracked spread's own trend now flags for review: in testing, moves that size behaved like news, not noise. Smaller counter-trend jerks tested as noise that fades — and the tested exit is unchanged: three Narrowing days make the call
A bigger spread lane — the hedge/compare lane is now nearly double height, with room to actually read
The lane's bars wear the trend — grey when the spread is quiet, green through a Widening run, red through a Narrowing run, amber at transition moments including the third straight Narrowing day, where the tested exit fires. Each colored stretch opens with its ▲/▼/◆ marker, single-day flickers stay grey, and the label counts a live Narrowing run day by day
Earnings at the lane's floor — when comparing, both legs' E marks live on the lane: amber for the focus leg, purple for the compare leg
Your tested window, visible — a tracked pair shades days 10–21 from entry right on the lane
One meaning per line style — the compare line is now solid purple; dotted belongs to the raw price line alone
The lane got an honest ruler — spread values now measure from the chart's six-month start at every zoom, so a day's number never changes when you switch windows; the axis fits the visible range in ratio, and the zero line appears only when the window actually crosses it. Track the pair and a dotted line marks your entry level (above it, the trade is paying), with the readout counting pp since entry
Urgent rows light up — a tracked position whose leg reports earnings today or tomorrow now wears an amber row in the tracker, with the legs and dates named. The one deadline a position can't wait out, impossible to miss
Board tenure now survives the day — an intraday wobble that briefly breached the grace band could quietly reset a pair's day count to 1. Departures are now decided once per day, on settled closes, the way the retention design always intended
v1.24
Hot-sector timing on Hedge Ideas — cards now note when a pair's sector just had a violent day, in either direction: our testing found entry timing around those days matters, and a pair tracked on such a day keeps the note in your tracker, which also tells you when a washout entry's tested window has passed. Information, not a gate — entry rules and the tested exit are unchanged
Sharper search — exact and closest ticker matches now come first: typing V finds Visa before anything merely containing a V
v1.23
Your tracker follows you — sign in and the Outlook Tracker syncs to your account: track a pair at the desk, check on it from your phone. Removing a tracking on one device removes it everywhere; signed-out tracking keeps working on this device as it always has
Departures, explained in place — when pairs leave Hedge Ideas, the bell and the Daily Pulse now carry a ? that opens the manual's why-pairs-leave passage, and multi-pair departure events list each pair as a link that charts it
v1.22
Track the same thing more than once, sanely — the chart marks the latest entry with a +1 count for earlier ones, the tracker groups a name's trackings together newest-first, and the ticket lists your tracked dates for the focused name, each clickable
Tracker tickers are links — click a tracked name to load it on the chart, or a tracked pair to load both legs with the spread lane up
The Daily Pulse rings the bell — each evening's fresh Pulse pins to the top of the notifications panel in its own green card, counted as unread until you've looked; once the market moves on the card greys out and shows when the next Pulse lands, in your local time
Peer rank is now Sector rank — same dial, clearer name: where a name stands within its sector, no longer confusable with True peers; tiles in that view now show the sector percentile
Agreement, counted in full — the Confidence view now tallies all ten of the engine's checks (8/10 signals), with stability as the tenth: steady behavior confirms the read, a sustained shock votes with or against it, and a fresh one abstains. Tiles mention volatility or tape only when they're working against the name — and when violent volatility is all that kept a near-unanimous read below High, the tile says so
Confidence you can open — Engine components now shows every check's verdict (✓ ✕ —) oriented to the call; tracked outlooks flag when confidence fades from your entry; and the manual carries the tested finding that near-unanimous bullish reads beat split ones by a wider margin
v1.21
Improved Hedge Ideas — pairs enter on strict conditions and now remain listed while the thesis holds, instead of dropping on a one-day score wobble; cards show days on the board and a holding tag on pairs riding out a wobble. Backtested first: pairs held through a wobble went on to outperform fresh entries
Board departures now mean something — a pair leaving Hedge Ideas signals its thesis actually broke, not that the tape had a red day; multiple same-day departures collapse into a single bell event
Your entry, on the chart — tracking a name or a pair draws a dashed marker on the CRP graph (and in the spread lane for pairs) at the day you tracked it; click it to jump straight to that trade in the tracker, which lights up on arrival. The marker lives exactly as long as the tracking does
v1.20
Track any pair you can chart — the compare chart gains ＋ Track pair: board pairs and custom pairs alike freeze at the lane's equal-risk sizing; custom pairs get drift-from-entry review flags instead of the board's entry rules, and a note if they didn't clear the hedge bar
Track from the profile — the Hedge idea row on every symbol ticket carries the same ＋ Track button as the board cards
Earnings inside the window — Hedge Ideas cards and tracked pairs now flag when either leg reports within the holding window, date included; spreads get noisy around reports
After-hours, the honest way — at the close the headline day-change freezes at the official print, and the evening drift becomes its own small AH number vs today's close, matching broker convention
Digest links — every event in the evening email now opens its chart on the desk directly
The recap page becomes the Daily Pulse — with a sector rotation line under the regime, leaders and laggards that click through to their charts, regime events that open the Market view, and clearer wording on past days
The manual's Back to the desk button now rides along as you scroll
v1.19
Fund drivers — sector tickets now show which members actually move the fund and by roughly how much, measured from co-movement rather than copied from a holdings sheet; SPY shows the names that track the index closest
Tracker polish — ＋ Track stays ✓ Tracked while a pair is in your tracker (click it to jump there), every flagged row carries a ↗ that opens the chart in a new tab, and expression legs are colored by side
A face for the tab — TradeMath's mark now shows as the site favicon
Honest pre-market changes — the day-change % now anchors to the prior session's official close, and settled bars re-verify against the official print after the extended session ends; a subtle data quirk had pre-market changes measuring one session too far back
v1.18
Track the trade, not the idea — hedge pairs and Relative expressions can now be tracked: legs, sizing and entry day are frozen at the click, and each row shows the spread since entry at your entry sizing
A tested exit, on every tracked pair — we made the exits compete on replayed trades: three straight Narrowing days (or about four weeks) kept the return of the flat hold in a quarter less time with a smaller worst case; tracked pairs now flag it, alongside the day count of the measured 10–21 day payoff window
Honest staleness — tracked outlooks and expressions flag when the read has moved against your snapshot: thesis weakening, thesis flipped, leader faded, laggard recovering; a pair leaving the board is a review prompt, not an exit (tested — exiting there was far too early)
True-peer marks — ◆ on Hedge Ideas cards and expression legs when the two names genuinely move together after the market's influence is removed: a tighter hedge, worn as a label (it deliberately doesn't change the rankings)
v1.17
The market in quadrants — the Market tab's sector cards now read as a rotation map: Leading, Weakening, Improving or Lagging from position and direction together, with split and quiet tags marking sectors at war with themselves or asleep
A daily recap page — /daily carries each close's signal events, regime, hedge board and leaders for the last 30 trading days; shareable, linked from the footer and the bell
The bell, delivered — switch on the evening email digest in the account menu: days with signal events land in your inbox once, quiet days send nothing, and unsubscribe is one click

v1.16
Ten more names — the universe reaches 145 stocks: BBY, EXPE, WDC, SNDK, STX, NBIS, LITE, CIEN, CRWV and COHR bring retail, travel, storage, optics and AI infrastructure aboard
True peers — every stock now lists the names it actually moves with, measured from co-movement with the market's influence removed, not borrowed from a category list; peers can cross sector lines (marked ◆), and one click overlays them on the chart
Honest silences — names with no close co-movers say so instead of padding the list
A proper footer — key links, and a plain-language reminder that TradeMath is an analysis tool, not investment advice

The bell rings — signal events now flow nightly: strength runs, leadership crossings, stretch warnings, and hedge ideas arriving or retiring
v1.14
Signal events — a bell in the header now collects what changed after each close: strength runs starting or ending, names crossing into leadership or weakness, stretch and washout warnings, and hedge ideas arriving or retiring with the reason
Dollar-template tickets — the Relative expression spells out every leg in dollars, anchored at $1,000 on the main leg; the manual walks the conversion to shares

Market Internals polish — the side cards and the big chart share one height, and the chart fills its panel on smaller screens

Energy, properly peopled — the sector nearly doubles, now spanning majors, natural gas, energy tech and carbon capture; solar and grid names join Technology and Industrials where they officially belong
Stronger data connectivity — live prices now travel multiple routes with automatic failover, and recover in minutes when a source hiccups

Smarter weakness reads — deeply discounted names flag bounce risk instead of avoid
Relative expressions re-sized — the same equal-risk rule as pairs, so the basket tracks the relative move
Hardened live feed — automatic recovery within minutes when the data source hiccups
v1.10
Smarter hedge-pair selection — partners are chosen for how well the pair trades together, spread across each sector
Unified equal-risk pair sizing — one rule everywhere: $1 long : $X short, both legs carrying the same daily risk
Improved dynamic beta calculation — β adapts to how a name trades
Consistent Signal Heatmap tile sizing

v1.6
Cleaner layout — universe chooser, search and filter moved into the heatmap header; sector view now lists a sector's stocks beside its detail
'At open' baselines across Market, Sectors and Stocks — every card (and the selected name's Alpha) shows where it opened so you can see the move since the open; the regime now updates live through the session too
Finer Alpha scale — scores now spread across the range instead of bunching near the top, so leaders are easier to separate
Cap-weighted sector breadth — uses real index composition so big constituents count for more
Clearer neutral calls — a name too weak to lean is shown as Neutral rather than a faint direction
Volatility-aware scoring — Alpha is de-rated and conviction lowered when a name is unusually volatile versus its own history
Early-warning tags — ⚡ flags a sharp counter-trend move to watch; a move that persists shifts the score itself
Alpha history on the chart — bars on the right axis show how a name's score evolved alongside its relative strength
