BookDepthIQ-Vest

_{Free to use. If it helps your trading, leave a tip, any amount you like. Secure checkout by Stripe.}

A depth-ladder (DOM) scalping panel for Vest Markets perps, starting with NQ. It runs as a Chrome extension next to your logged-in Vest tab. You get a price ladder with live Vest book, tape and volume, one-click market, limit and scale entries with TP/SL brackets (up to three partial targets), $-risk sizing, a stop and targets you can preview on the ladder before you enter, trade management (B/E, trailing stop on R or SuperTrend, close half) and one-key flatten. A RISK calculator (any market, Instant and Funding/evaluation account presets) sizes your trades and writes the plan into the ticket, and a SuperTrend scalp read in the header tells you when an ST1 scalp is a pullback worth taking and when it's a chase. Every order goes on one click; an order log records each click and what became of it, and the journal matches your Vest position history. New since 1.4: see What's new.

Companion: Vest Liquidity Scanner ranks all of Vest's markets by real trading, volatility and trend vs chop, so you know which one to open in this panel. Read-only, separate install. Clicking a scanner row switches this panel to that market (through a #bdiq-switch marker on the Vest link it opens; nothing but the instrument changes, and held stops disarm as on any switch).

⚠️ BETA — read this before you trade

• It works, and it is still beta. Every LIVE action has been in real use on Vest since 2026-10-08: market entries, ladder limit orders, order drag, TP/SL drag, B/E, FLATTEN and CANCEL ALL. Beta means it hasn't been tested on many accounts or setups yet. Confirm your first trades on Vest's own screen.
• Vest publishes no trading API. The panel sends the same requests Vest's own web app sends, using your existing login. If Vest changes its app, things can break without warning. Watch the result bar under the LIVE banner and keep Vest's own tab open to confirm every order.
• Prop-account terms are your responsibility. Vest's Prop Terms treat API access as a feature Vest controls and allow one account per person. Using a third-party panel may be treated as unauthorized use. Read the terms and decide for yourself.
• Manual trading only. The panel has no algos, no auto-entry and no copier. Nothing OPENS a position without your click, an armed hotkey or a stop you armed yourself. A few management features you can turn on (B/E after TP1, trailing stop, stop guard, close at your daily loss limit, close before the weekend lock) move a stop or close a position without a click; all are off by default (see Safety rules).
• Not financial advice. No warranty (MIT). Start with the smallest size Vest allows.

What you need

• Google Chrome (or another Chromium browser that supports Manifest V3 extensions)
• A Vest account you can log into at https://next.vestmarkets.com
• Node.js 20 or newer, to build the extension once

Install

Easy way (no Node needed):

1. Download the latest BookDepthIQ-Vest-vX.Y.Z.zip from Releases.
2. Unzip it to a folder you'll keep, for example C:\BookDepthIQ-Vest.
3. Open chrome://extensions and turn on Developer mode (top right).
4. Click Load unpacked and pick the unzipped folder.
5. Pin the BookDepthIQ-Vest icon in the toolbar.

To update: download the new zip, unzip it over the same folder, press reload on the extension in chrome://extensions, then reopen the panel.

From source:

git clone https://github.com/autopilotaitech/BookDepthIQ-Vest.git
cd BookDepthIQ-Vest
npm install
npm run build        # creates dist/ — load this folder with "Load unpacked"

First run: PAPER

1. Click the toolbar icon. The panel opens in its own window.
2. It always starts in PAPER. Orders fill locally in this window and nothing goes to Vest. The banner says so.
3. Pick a market (NQ-PERP by default) and learn the ladder in PAPER first.

Going LIVE

1. Open https://next.vestmarkets.com in the same Chrome as the panel and log in. Keep only one Vest tab open (see Troubleshooting).
2. Open the panel and wait a few seconds. The red "no Vest login" text next to the switch should disappear.
3. Press LIVE. The panel reads your Vest account and asks: "LIVE: orders go to <account>. Continue?"
4. The banner turns red: LIVE — <account> — real orders. The account row shows your Vest balance, the fail floor (max_drawdown_limit), leverage, trading power and sync status.

Every LIVE launch starts in PAPER again. LIVE is never remembered.

Using the ladder

Action	PAPER	LIVE (real orders on Vest)
BUY MKT / SELL MKT buttons	market fill	market order, with TP/SL legs if BRACKET is on
Click the BUY / SELL column at a price	limit order	limit order (GTC) with TP/SL legs at your points from that price
Click with SCALE ON	2–10 limits	scale order like Vest's own: the first limit opens, the rest are added to the same position (no TP/SL)
Shift+click the BUY / SELL column	stop order	panel-held stop: a buy stop above the ask or sell stop below the bid. When a trade prints at or through it, the panel sends a market entry with your TP/SL (dashed STP chip; click to cancel, drag to move)
Click an LMT chip	cancel	cancel on Vest
Drag an LMT chip to another row	move	move on Vest (cancel, then re-place the unfilled size at the new price; TP/SL shift with it)
Drag a TP / SL chip	move the leg	move the leg on Vest (each partial target on its own)
Drag a ◇ preview stop / target	change your stop / target distance	same — nothing is sent
B/E	stop to entry ± offset	moves (or adds) the Vest stop
CLOSE HALF	half at market	half at market on Vest (never blocked)
FLATTEN / F	close all	closes the Vest position, then cancels its resting orders
CANCEL ALL / Esc	cancel all	cancels every resting Vest order on the symbol
REVERSE / adding to an open position	yes	not yet (paper only)

Reading the ladder (columns, left to right)

Column	Shows
Buy / Sell	where you click to place limits; your order and TP/SL chips
Sold / Bought	footprint: volume that hit the bid / lifted the ask at each price. A cell lights up when one side outweighs the other diagonally by the imbalance ratio (default 3:1, in settings); a white edge marks 3+ in a row (stacked)
Bid liq / Ask liq	resting size as heat; WALL = at least 3× the average level
Price	value area tinted, POC outlined, last trade and your average marked
Volume profile	session volume per price as a grey histogram, as in the NT DOM: POC brightest, 70% value area lighter, the rest dim. No numbers; buyers vs sellers is the Δ column
Δ	bought − sold at each price, a bar from the column centre: cyan right = buyers, orange left = sellers (hover a row for the number; click the header to hide)

The position strip also shows points to your fail floor, POC and value area, the session cumulative delta with a sparkline, and the bid/ask split of visible liquidity. Volume, footprint and delta count from when the panel opens.

Dual SuperTrend (same engine and settings as BookDepthIQ)

• ST1 (solid line, 60 s candles, 10, ×3.6) and ST2 (dashed, 15 s candles, 10, ×3.0) are drawn across the ladder at their price, green when the line is support below price, red when it is resistance above, with ▲ ST1 / ▼ ST2 tags on the price column. Off-screen they pin to the ladder edge with the distance in points.
• They update at each candle close: the line only ratchets with the trend and flips when a candle closes through it and that candle's delta agrees.
• The header badge shows the combined state (▲▲ STRONG LONG … ▼▼ STRONG SHORT) and confidence, and pulses on a flip. The strip shows points from price to each line. Toggle with ST in the tape header. On open it loads the last ~45 minutes of Vest trades ("SuperTrend loading 45 min…"), so ST1, ST2 and the market state are right from the start instead of after 10+ minutes.

VWAP, imbalances and big trades (settings → Indicators, one set for every instrument)

• VWAP with σ bands (default 1 and 2), anchored to your session start/stop time and time zone (default 09:30–16:00 New York). On open the panel pages in that session's trades from Vest, so VWAP is right even if you open the panel late. Drawn as a purple line with dashed band lines; the strip shows VWAP and how many σ price is from it.
• Footprint imbalances: ratio, minimum volume (% of the busiest row), stack size, and zone lines for stacked imbalances (▲ support at the bottom of a buy run, ▼ resistance at the top of a sell run). Turn the whole thing off in the same section.
• Big trades (tape only): prints at or above your size (default 8u ≈ the top 1% of Vest NQ prints) flash when they hit and stay highlighted on the tape: bold, tinted by side with a side edge, a size bar and "B 12.40" / "S 9.80". At 3× your size they are larger and stronger.

RTH opening range (NQ and ES only — the same PAXOR logic as BookDepthIQ)

• OR H / OR L from the trades in the first 30 seconds after the 08:30:00 Chicago bell, drawn as solid lines (blue high, red-orange low); dashed and marked "forming" during those 30 s.
• EXT rungs every 65 pts on NQ / 15 pts on ES beyond the range; each time price breaks the outermost rung the next one appears (EXT1, EXT2, …). Optional mid line.
• Like BookDepthIQ's engine, the range stays up until the next weekday bell (Friday's carries to Monday) and the EXT ladder keeps growing until then. Opening the panel late is fine: it pages in the bell window and every trade since from Vest (a busy day can take a few seconds). The strip shows the range, its size in points, and whether price is above, inside or below it. Settings → Opening range (bell, window, time zone and EXT steps are editable; drawn only on NQ and ES).

Funding (Vest settles funding hourly, on the index notional)

• The position strip shows Vest's current hourly rate and its yearly equivalent, who pays (positive: longs pay shorts), minutes to the next settlement, your $ per hour for the position you hold (red in the last 5 minutes if you are about to pay), and a predicted rate: this hour's average premium put through Vest's published formula.
• prem 5m in the header is the live premium the way Vest measures it (impact prices for a $100 ÷ initial-margin order vs the index). NQ/ES/RTY trades are blocked beyond ±25 bps of the index (BTC/ETH ±50), so it turns amber near the band, where price tends to snap back.
• For a scalp, funding is small: NQ at the ±25 bps limit is ≈ 0.005% an hour (≈ $0.16 on 0.1 units) and nothing if you are flat at the top of the hour.

Cost panel (above the buttons): what an entry really costs, before you click

• Spread light: green CHEAP = the spread is at or below this market's median for the last 5 min, amber = normal, red WIDE = above its p90 (wait, or use a limit). It shows "learning…" for the first few minutes.
• BUY ≈ / SELL ≈: your fill price for the current size, worked out from the live book. Amber slip means your size reaches past the best price. The estimate also shows on the BUY MKT / SELL MKT buttons.
• Break-even: points price must move your way to cover the spread both ways, any slippage and both taker fees, plus its $ and share of your drawdown room.
• TP = N× cost: your TP distance divided by break-even. Under 2× (amber/red) the trade mostly pays the spread.

Sizing and brackets (bottom bar)

• Size can be in units, USD notional (like Vest's own ticket) or $ risk at the stop. The equivalent CME contracts, notional, leverage and round-trip cost are shown underneath.

• TP pts / SL pts: distances in points. They're your numbers; the panel has no built-in defaults. 0 means no leg. BRACKET ON/OFF toggles legs for new entries.

• B/E + pts: the offset used by B/E.

• TP2 / TP3 (second row): more targets, each further than the last. With two or more set, split (e.g. 50/30/20) says what share of the size each one closes, and the ticket shows the units and $ per target. B/E after TP1 moves your stop to entry ± the B/E offset once TP1 fills (see Safety rules).

• SCALE ON: a ladder click places 2–10 limits from the clicked price, over pts further away from the market, sized evenly or with a skew toward the start or the end, like Vest's own Scale ticket. Shift-click is still a stop. Scale orders carry no TP/SL (Vest's don't either): press B/E once filled.

• Risk buttons ($25 / $50 / $100 / $200, editable in settings) size the trade so a stop-out costs that much, taker fees both ways included. $ risk sizing always counts the fees.

• STOP PTS / ATR / SWING: in ATR mode the stop is the ATR of the 60 s candles (the ST1 engine) × your multiple. In SWING mode a long's stop goes under the low of the last N minutes and a short's over the high, plus your buffer, so it sits beyond the structure, and never closer than your ≥ min (0 = no floor; an entry right at the high/low would otherwise get a stop inside the noise). The ticket shows both sides (L x / S y pts) and, in $ risk sizing, both sizes. In both modes the targets are R multiples of the stop and the size follows it, so the $ risk stays the same.

• setup tags the next trade (edge fade, breakout, pullback, trend…) for the journal.

• PREVIEW LONG / SHORT shows the stop and targets (◇, dashed) on the ladder before you enter, with their $. Nothing is sent. Drag the ◇ stop to change it: in $ risk sizing the size follows, so the risk stays the same. In ATR mode snap back returns to ATR × multiple.

• CLOSE HALF closes half the position at market. Like FLATTEN, it is never blocked. Partial targets shrink from the furthest one.

• trail (from 1R / 1.5R / 2R): once price is that far in your favour, the stop follows the best price one risk behind and only moves your way. Picking a trail while you are already in a trade applies it to that position at once; off ends it. on ST1 / on ST2: the stop sits on that SuperTrend line while the line is on your side (under a long, over a short), and never moves back; a flipped line leaves the stop where it is. stop guard (LIVE): if a Vest position loses its stop, the panel puts it back at the last price and shows a red warning.

• Protect my day (settings; all off by default): a daily loss limit (with also close open trades), max trades per day, a cooldown after a loss, and close before the weekend lock. The day starts 17:00 Chicago. When the room left is smaller than your usual risk, size to fit offers the size that fits. The header shows day $ / limit · trades and LOCKED when entries are locked. Exits are never locked.

In a trade. A bar under the position row puts the stop, your entry, the price now and every target on one line, with the $ at each, and worst case now (what the stop costs if it fills, exit fee included; with no stop, the room left to the fail floor). On the ladder the same stop, entry, targets and trailing line are drawn across the rows with their $ (dashed while previewing). The fit button in the price header widens the rows so all of them are on screen; leave it off when placing orders, because wide rows place at the row's price. In LIVE, a room to floor bar under the account row shows how much of the drawdown allowance is left (amber under 50%, red under 25%).

Hotkeys

• F = flatten and Esc = cancel all. Both always work.
• B buy, S sell, E B/E and R reverse work only while HOTKEYS ARMED is on. Click the toggle to arm them. They start on SAFE each time the panel opens and go back to SAFE when you go LIVE; pressing one on SAFE says so in the amber bar and the order log.
• Space re-centres the ladder. Otherwise the ladder holds still and re-centres only when price drifts a sixth of the screen from the middle. While your mouse is over the ladder it doesn't move at all (unless price nears the edge), so the row you aim at stays put.
• Wheel over the PRICE column changes the price grouping: 1, 2, 4, 8, 20, 40 or 100 ticks per row.

SuperTrend scalp read (header): which side ST1 is on and whether to take the scalp now. ▲ SCALP LONG — pullback to ST1 (solid) when price is within 2 ATR of the ST1 line and the last 5 minutes are pulling back; LONG side — wait for the dip when it's near but still running; STRETCHED x ATR — don't chase past 2 ATR, with a dotted NO CHASE line on the ladder at ST1 ± 2 ATR. Measured on 72 h of Vest NQ (ST1-side scalps at every 1-minute close): at 10/10 pts the GO read won 63% (+1.3 pts/trade after ~1.25 pts round-trip taker fee); stretched won 48% (−1.7 after fees). At 5/5 pts even GO lost after fees: base hits need ~8+ pts on NQ. Past results on one sample, not a promise.

Market state (in the scalp badge's tooltip; "· chop" on the badge), read from price, not SuperTrend flips: TREND ▲ / ▼ when the last 15 minutes went one way efficiently (net move ÷ path ≥ 0.3) and far (≥ 3 ATR of the 1-minute bars), held until it clearly fades; CHOP — fade the edges otherwise, with the last 30 minutes' RANGE H / RANGE L drawn on the ladder (pinned at the edge when off-screen); EXTENDED, don't chase when price is 2σ+ from VWAP or 3+ ATR from ST1. It describes the market; it doesn't call trades.

Journal (the journal button top-right, in the Vest tape header next to ST on and hide log; click again for the tape): every round trip, with the setup tag, size, entry, stop, $ result and R, totals and results per setup, and copy CSV. PAPER results are exact (fees in). LIVE rows sync with Vest's position history (v1.9.3): a few seconds after each LIVE close, when you go LIVE, and on sync Vest. Each row takes Vest's own entry, exit, size, P&L and funding, and Vest trades the journal missed (other markets, Vest's own page) are added. The P&L column is Vest's (open vs close price, fees not included, as on Vest's history); the line under the totals shows net after fees + funding. A row still marked ≈ has not been matched yet. Kept in this browser.

Risk calculator (v1.9): the RISK button in the header opens it over the panel. It reads your account (LIVE: balance, fail floor and per-market leverage from Vest; PAPER: the paper account) and Vest's live prices. It never sends an order.

• Pick any market (filters: Futures NQ ES YM RTY GC SI HG PL CL BZ NG, Crypto, All), Long/Short, and size by stop + $ risk (a % of the room left to the fail floor) or by leverage. Each market's cap is Vest's 1 / initMarginRatio, capped by your account.
• Shows size (with the CME contract equivalent), leverage used vs cap, $ lost at the stop and won at the target after fees, R:R, a risk map (target, entry, stop and the price where the account fails), what a move is worth ($ per point, per 10 points, per 0.1% / 1%, fees), how many losers like it the room holds, and a leverage chart: points left before the account fails at each leverage, with the leverage above which your stop is past the fail line.
• Every market table: same account and $ risk, stop at the same % of price — cap, how far a max-size position can move before the account fails, size, leverage, $ per point and per 1%. Click a row to load it.
• Instant accounts work everywhere risk is counted. Account: Mine (tagged "Instant $500" etc. when its start value and floor match a package), Instant ($500 / $5K / $10K / $25K; static drawdown $10 / $200 / $400 / $1,000 as listed publicly, 25x) or Custom. The Instant floor is static, so typing your balance now shows your room (profit adds to it). The paper account's settings have the same Instant buttons. Check your own Vest screen.
• Funding (evaluation) accounts: Account → Funding: Silver $5K / Gold $10K / Platinum $25K, 6% static max drawdown (floor $4,700 / $9,400 / $23,500), and the daily loss limit of your plan (3% / 4% / none). With a daily limit, today's room is the smaller of the limit and equity − floor. The note shows the 1-Step targets (10% / 20%) and 2-Step (10% then 5%); the funded account you get on passing has the same rules. Numbers from Vest's own account tiers page; every box stays editable. Paper settings have Funding buttons too.
• Use in DOM writes the plan into the ticket: size mode % room @SL (the $ risk follows your room as it changes), SL and TP points, and opens that market if it isn't on screen.
• My max lev: over it, the ticket warns (nothing is blocked). The ticket also shows % of room · losers left, and warns on an entry whose stop is past the fail line. With PREVIEW on, the FAIL line is on the ladder before you enter.

Pro tools (v1.8)

• Header pills: FEED (green under 2 s since Vest's last message, amber, then red STALE: the ladder greys out and an entry warns, but still goes) and, in LIVE, VEST (⚡ push with Vest's median answer time for your orders, POLLING, or STALE).
• KILL ⏻ (or Ctrl+K, from anywhere): closes every position on every symbol at market and cancels every order, PAPER or LIVE. Never blocked.
• Order status (LIVE): each resting order chip says where it is (· ACKED / WORKING), and the blotter under the ladder lists the last requests: SENT → ACKED → WORKING → FILLED / GONE, or REJECTED with Vest's reason, with Vest's answer time. NO ANSWER = still waiting after 3 s: check Vest before you resend.
• Fat-finger checks above the ticket line: size vs your normal (last 20 journal trades), spread, distance of a limit/stop from the market (settings: far from market pts, 0 = 4 × ATR; size × normal), stop inside the spread. Warnings only (v1.9.2): one click always sends, like Vest's own ticket; the warning shows in the amber bar and the order log.
• Day lock bar: when Protect my day locks entries, a red bar over the ticket says why and that exits still work.
• heat 5m · pull/stack column (toggle heat in the tape header): resting size at each price over the last 5 minutes, one cell per 10 s showing the AVERAGE size over those 10 s (left = older; cyan = it was a bid then, orange = an offer, brighter = more; yellow = a wall, 3× the typical cell), then size pulled (− red: left without trading) or stacked (+ green) over the last minute. ABSORB bid = sellers kept hitting that bid (at least your big-trade size, and 2× the buying there), more than was showing when they started, the level held (no trade below it since) and at least half the size is still there: buyers absorbing (a cyan ABS badge at the left of the cell). ABSORB ask is the same at an offer (orange ABS). The market maker's constant re-quoting plays no part.
• Replay: the panel records the market on screen (book 4×/s, every trade, ticker) into this browser, kept 7 days. Replay ○ in the header lists the recordings; ▶ start plays one through the ladder in PAPER only (LIVE is off; a fresh paper account), with « 1m / 1m », 1–10× speed, a position slider with your replay trades as dots, and the replay P&L. exit replay brings the live market back.
• Journal execution: each trade records the price you expected when you clicked, slippage (+ = worse), the entry fee, maker/taker and Vest's answer time; the journal shows averages and the CSV has the columns.

The result bar. Every LIVE action shows its result right under the LIVE banner: green ✓ when Vest accepted it, red ✗ with the reason when it was refused. The full request/response log is in the LIVE LOG pane. Its copy button copies it with your login already blanked out.

Order log (v1.9.2; click log in the tape header): every order click and hotkey (PAPER and LIVE) with the size it used and the bid/ask, any warning, anything that stopped it before it was sent (day limit, hotkeys on SAFE, no market loaded), Vest's answer, and any error in the page. It is kept across reloads. copy puts it, with the mode, market, feed health and size settings and the LIVE request log, on your clipboard — paste that into a bug report.

What's new

Version	What changed
1.10.2	Volume profile and Δ match the NT DOM: the profile is a grey histogram (POC brightest, value area lighter, no numbers or labels) and Δ a cyan / orange bar from the column centre (hover for the number). Settings › Colours: Profile bars, Profile value area, Profile POC.
1.10.1	Heat window on the ladder: click the heat column header to step 5 → 15 → 30 → 60 min; the HEAT chip and the header show the window, and the tooltips give the real slice and pull/stack spans.
1.10.0	Settings screen (SETTINGS in the header): a section rail (Account, Fees & warnings, Protect my day, Ladder, Indicators, Opening range, Colours) with ON/OFF switches and segmented choices, replacing the fold-out settings. Colours: every panel colour is editable, with presets Default / Midnight / Graphite / High contrast, a picker + hex + reset per colour, live. One indicator set for every instrument (your settings carry over). Opening range bell, window, time zone and NQ/ES EXT steps are editable (defaults 08:30:00 Chicago, 30 s, 65 / 15 pts). Account tiles: EQUITY or BALANCE, ROOM with a bar, LEVERAGE, POWER, MAX SIZE (Vest status and rate in the tooltip). Tape toolbar chips (JOURNAL · LOG
1.9.3	BUY/SELL never go silently dead: a click that can't send says why (size 0, no book, waiting on Vest), and a Vest request gives up after 12 s instead of leaving entries off. reset button on RISK (back to the defaults). Journal matches Vest: LIVE rows take Vest's own entry, exit, P&L and funding from its position history (auto after each close, on going LIVE, and sync Vest); Vest trades the journal missed are added; net after fees + funding line.
1.9.2	Orders go on ONE click again: fat-finger checks and a stale feed warn instead of blocking. Order log (click log): every order click, hotkey, warning, block reason, Vest's answer and any error, kept across reloads, with copy. Hotkeys on SAFE say so instead of doing nothing. RISK: Funding (Silver/Gold/Platinum evaluation, 6% static floor, daily 3%/4%/none) next to Instant; Funding presets in paper settings.
1.9.1	Stop entries fire on touch only: the trade that reaches your stop price fires it (PAPER too, from the tape). The 1m CLOSE option is gone.
1.9.0	RISK calculator inside the panel (any market, live prices and leverage caps, risk map, leverage chart, every-market table, Use in DOM), % room @SL sizing, your own max leverage, fail-line check and preview FAIL line. Instant accounts ($500 / $5K / $10K / $25K, static floor) in RISK and the paper settings. SuperTrend scalp read (GO on a pullback to ST1 / wait / STRETCHED, NO CHASE line), TREND/CHOP read from price.
1.8.4	Heatmap logic: 10 s cells are time-averaged (steady instead of random), coloured by the side the price was on then, brightness against the 90th percentile, yellow = wall (3× typical).
1.8.0	KILL, FEED/VEST health pills, LIVE order status + blotter, fat-finger checks (second click), day-lock bar, heat/pull/stack column, record + replay, execution columns in the journal.
1.7.1	Swing stop ≥ min floor; SuperTrend loads 45 min of history on open; RANGE H/L pinned when off-screen.
1.7.0	SWING stop, STP 1m CLOSE stop entries, market state (TREND / CHOP / EXTENDED) with range lines, trade journal with setup tags. Off-screen labels take one line instead of crowding out the ladder. PAPER keeps the stop and targets from the click (an ATR or swing stop no longer changes at the fill).
1.6.5	The trail menu applies to the position you're already in, not only the next entry.
1.6.4	Calm ladder: re-centres only when price drifts a sixth of the screen, and holds still under your mouse.
1.6.3	Trailing stop on SuperTrend: on ST1 or on ST2.
1.6.2	fit button (off by default) instead of always widening the rows. ATR mode warns when there is no stop yet.

Safety rules built in

• FLATTEN and CANCEL are never blocked. No mode, guard, failed read or expiring login stops them.
• Entry checks: the size must fit your trading power, the account must be above its fail floor, positions must be freshly synced from Vest, and there must be no position already open on the symbol. These are the same limits Vest's own ticket enforces.
• Optional size cap: settings → Account → LIVE size cap. 0 means off.
• RISK never sends an order. Use in DOM only fills in the ticket (size rule, stop, target). An entry over your own max leverage, or with its stop past the account's fail line, shows a warning; it still goes on one click, as on Vest's own ticket.
• Panel-held stops are the only orders that fire without a click. They live in the panel, not on Vest: close the window, switch instrument or go to PAPER and they are disarmed (the header shows ⚡ N stops armed while any are live). Each one fires once, through the same checks as a click.
• Other things that act without a click, each off until you turn it on, and none of them ever opens a position: B/E after TP1 (one stop move when TP1 fills), the trailing stop, stop guard, close at the daily loss limit and close before the weekend lock. They need this window open. B/E after TP1 and the trailing stop disarm like panel-held stops, and on FLATTEN or CANCEL ALL.
• Vest is the source of truth. Positions, orders and balance come from Vest and are never computed locally. Vest pushes account changes over its private socket, and the panel re-reads them at once (the account row shows Vest ⚡ live). If the push drops, it falls back to reading every 1.5 s (Vest synced (polling)).
• Your login stays in memory. The extension reads the token your Vest tab already uses. It is never written to disk, never logged, and never sent anywhere except Vest's own API.

Troubleshooting

You see	Do this
"no Vest login — no next.vestmarkets.com tab is open in THIS Chrome…"	Open Vest and log in in the same Chrome window set (same profile) as the panel.
"no Vest login" after reloading the extension	Reload the Vest tab once, then wait about 3 s.
Login flickers, or LIVE behaves oddly	Close extra Vest tabs. Keep one.
Pressing LIVE seems to do nothing	Read the red text next to the PAPER/LIVE switch. It says exactly why.
An order is refused	Read the red result bar under the LIVE banner, or the order log (click log).
An order doesn't go through and nothing says why	Click log, try once more, then copy in the ORDER LOG and send it. Hotkeys on SAFE do nothing but say so; click HOTKEYS SAFE to arm them.
The journal doesn't match Vest	Open the journal and click sync Vest. The line next to it says how many Vest positions were read, matched and added. The journal's P&L is Vest's (before fees); the net after fees + funding line is what your balance moved.
The header says STRETCHED — don't chase in a strong move	Price is 2+ ATR past the ST1 line; scalps from there lost on the measured NQ data. Wait for a pullback toward ST1 (SCALP LONG/SHORT — pullback to ST1).
RISK numbers don't match my account	Paper: settings → Account → Instant or Funding buttons, or type your start value, drawdown and leverage. LIVE reads them from Vest. RISK → Instant / Funding / Custom plans any other package.
Something looks wrong on Vest	Press FLATTEN, check Vest's own screen, then open an issue with the copied order log.

Reporting bugs

Open an issue at https://github.com/autopilotaitech/BookDepthIQ-Vest/issues with:

• what you clicked and what you expected

• a screenshot of the panel and of Vest's screen

Contributing

Feedback, ideas and pull requests are welcome. See CONTRIBUTING.md for setup and the rules for anything that touches LIVE trading. Parked ideas are in docs/TODO.md.

For developers

npm test             # unit tests (request bodies, guards, flatten-always-works, readers)
npm run typecheck
npm run build        # then reload the unpacked extension to try a change (Vest's API refuses
                     # requests from localhost, so `npm run dev` can't load market data)
npm run probe -- NQ-PERP 60   # measure the live Vest book for 60 s

Design notes are in docs/DESIGN.md, and the LIVE request shapes and safety rules are in docs/LIVE-ORDERS-SPEC.md. All Vest request bodies live in one file, src/vest/tradingShapes.ts.
