Windows reference

How to spawn

• ⌘K → type a crypto symbol (BTC, ETH, SOL).
• ⌘K → 'Open chart for X' as a fallback when the registry doesn't know the symbol.
• Workspace presets ('Markets', 'Research') include a chart in their layout.

Top bar

Pan & zoom

• Click + drag — sub-pixel pan with RAF-coalesced render. Release with momentum to fling-glide.
• Wheel — zoom (vertical) or pan (horizontal). Trackpad detected automatically and slowed ~12×.
• Right-edge price axis — click + drag up/down to stretch / compress the y range (TradingView-style).
• AUTO refits the y range to data; LOG toggles linear / log10 price mapping; MAG snaps the crosshair to the bar's nearest OHLC. Buttons sit bottom-right of the chart, just above the time axis.
• You can scroll past the latest bar into empty 'future' space (TradingView style).

Measure & export

• Shift + drag draws a measurement box with % change, $ change, bar count and elapsed time. The box stays after you release the mouse.
• ✕ on the toolbar clears the selection; starting a new Shift+drag replaces it.
• ↗ Sheet exports the bar range as a fresh spreadsheet (time + OHLCV per row), so you can analyse it with =VOL, =TREND, run regressions in the Lab, etc.

Hotkeys

Settings that affect it

What it does

Standard A1-style spreadsheet — type values or =FORMULAS in cells, drag column borders to resize. Persists to the unified file store with a 4-second auto-save debounce after the last keystroke; the status bar shows the dirty / saved state. Two-finger trackpad scrolling pans both axes; Shift+wheel scrolls the cross-axis on a notch wheel.

Live price formulas

Pull live ticks into cells. Crypto uses Binance (5-second cadence); equities go through Yahoo / Finnhub via the gateway (15-second cadence) — the source is governed by data.equityProvider in settings.

=PRICE("BTC")     # crypto last trade (auto-normalises to BTCUSDT)
=PRICE("ETHUSDT") # explicit pair
=STOCK("AAPL")    # live US equity quote

Financial modelling formulas

Closed-form scalar functions for the common quant primitives. They evaluate synchronously like any spreadsheet formula — drop them in alongside arithmetic and they recompute when their inputs change.

=BLACKSCHOLES(S, K, T, r, sigma, "call"|"put")  # option price
=VOL(A1:A60)         # annualised realised vol on log returns × √252
=TREND(A1:A60)       # OLS slope of y = i over the range
=ZSCORE(A1:A60)      # last value's z-score against the rest

Toolbar buttons

Selection

• Click + drag selects multi-cell ranges; selection persists after you release the mouse.
• Shift+arrow extends the selection from the anchor; the cursor side moves correctly past two cells.
• Selection border + interior flash track the active theme accent — when you arrow into a new cell the box pulses for ~220 ms.

How to spawn

• ⌘K → 'sheet' or 'spreadsheet' or 'sheets'.
• From the FileBrowser: double-click any .sheet file.

Tabs

Reading the spreadsheet

The Lab passes range strings (A1:A20) over a CustomEvent bridge to whichever sheet is currently active in the workspace — no React refs cross window boundaries, so the Lab keeps working when the spreadsheet is in a popout.

How to spawn

• From the spreadsheet: 🔬 toolbar button — passes the current selection's range as the default.

What it does

Takes a 2-or-more-column selection (header row + data) and renders the first column as the X axis and remaining columns as series. Series colours track the active theme — switching theme re-recolours the chart in place.

Export buttons

How to spawn

• From the spreadsheet: select a range, click the 📈 toolbar button.
• From the Lab: each tab has a 'Chart …' button after a run.

Modes

Syntax highlighting

Auto-on for filenames matching .js / .ts / .tsx / .jsx / .json / .mjs / .cjs or anything containing 'indicator'. The highlighter is a tiny tokenizer (comments, strings, numbers, keywords, identifiers) — not a full parser, but covers ~95% of code you'd write here.

Auto-save

4-second debounce after the last keystroke. The status bar shows dirty / saved / idle. Linked-mode commits every keystroke straight to the chart's indicatorCode (no debounce — the chart's sandbox throttles).

Routing

Double-click any file to spawn it in the right editor. Files are typed by extension and content sniff.

Indexing

Files surface in the command palette too — ⌘K then type any part of the filename. The palette indexes lazily on first open and refreshes whenever it re-opens.

The Watchlist is a textarea on the left and a price column on the right. Edit the textarea (one symbol per line, e.g. BTCUSDT, ETHUSDT, SOLUSDT) — the price column re-renders to match. Changes save back to the workspace immediately.

How it works

Each alert is a (symbol, direction, price) rule. The chart's tick stream feeds the alert checker; when a rule's threshold is crossed, the Finterm service worker fires a browser notification.

First-time setup

1. Spawn the Alerts window.
2. Add a rule (symbol, above/below, price).
3. On first arm, the browser asks for notification permission. Grant it.
4. Test by setting an above/below near the current price.

The feed pulls from /api/data/news/crypto, edge-cached for 2 minutes. Click any headline to spawn (or focus) a Reader window with the article's body extracted in-app — no leaving the workspace.

How extraction works

/api/extract fetches the URL with realistic browser headers, parses the HTML through htmlparser2 (a SAX streaming parser, no DOM), walks the tag tree picking up paragraphs / headings / lists / blockquotes / images, and returns a typed Block[] payload that this window renders.

The window calls /api/data/sec/submissions which proxies SEC EDGAR's submissions JSON, resolves your ticker to a CIK via the company-tickers manifest, and renders the recent submissions table.

Form filter chips

Toggle 10-K / 10-Q / 8-K / S-1 / 4 / DEF 14A / 13F-HR / 20-F. The text-search box filters by form code or document description on top of the chip selection.

Available metrics

• Flow: revenue, netIncome, grossProfit, operatingIncome, rd, opex.
• Per-share: eps, epsDiluted.
• Stock: cash, equity, assets, liabilities.

Loads OHLCV from any Binance symbol + interval, runs your strategy in the same Web Worker sandbox as indicators. Returns: trades + equity[] + P&L + max drawdown + win rate + buy-and-hold baseline.

Snapshot of the entire Binance USDT spot market. Refreshes every 30 seconds via the data gateway. Click any tile to spawn a chart for that symbol.

Pulls from /api/data/binance/funding (cached 30s). Sort by rate to find perp / spot dislocations.

Streams from wss://fstream.binance.com/ws/!forceOrder@arr — every liquidation across all USDS-M perps in real time. Filter by symbol prefix to focus on one cohort, or set a minimum-notional cutoff to drop dust.

The 'side' column is the side that got liquidated (LONGs got hit when price dropped; SHORTs got hit when price ripped).

Pick any USDT perp and a period (5m..1d). Pulls /futures/data/openInterestHist via /api/data/binance/oi-hist (edge-cached 30s). Shows current notional, contract count, window min/max/Δ%, plus a sparkline.

Useful for spotting positioning shifts: a sharp OI spike with flat price often precedes the move.

Single-page summary for one symbol. Useful as a sidebar companion to the chart — pin it next to the chart for the same ticker and you have price + book + stats without the chart's interaction surface.

Paste a list of symbols, pick a window length, get a heat-coloured matrix of pairwise rolling Pearson correlation. Useful for hedge-construction or basket research.

You add positions; the window pulls live mark prices through the data gateway and renders unrealised P&L per row. Persisted to the workspace alongside everything else.

Aggregates calendar items from the data gateway. Filter by category (earnings, macro, on-chain) and severity.

Free-text entries with structured fields. Persisted to the workspace + exportable as a CSV for tax / accounting workflows.

Pairs naturally with the Portfolio window. Computes risk metrics over the position equity curve over a configurable lookback.

Two ways to edit settings: this GUI, or the JSON editor (open with 'settings' in the palette). Both write through the same store, so changes round-trip across the two.
