The order-flow terminal for crypto
Every resting order and every trade on Binance, Bybit, OKX, Hyperliquid, Aster, Lighter, Coinbase, Deribit and Kraken: heatmaps, footprints, DOM and tape, with paper and live trading. In the browser or as a desktop app.
Free with an account. Runs in the browser, nothing to install.
Order flow, the way it trades
Live from each venue's own websocket, drawn on the GPU, and every view works on aggregated markets.
Every resting order, over time
Walls building, pulling and getting eaten show as lines per price level, with the trades that hit them as bubbles and the live book beside the chart.
- The exact order book: a snapshot plus every sequence-checked change, never sampled
- Price levels of about 0.001 % of the price
- A choice of colour ramps and a range slider for faint or heavy books
What traded inside every bar
Bid × ask, delta or volume at each price of the bar, with the value area, naked points of control and imbalances marked.
- Stacked imbalances, absorption and naked POCs as studies
- Missing minutes backfilled from the venues' trade history
- Bar Stats under the chart: volume, delta, trades, OI change, liquidations
The ladder and the prints
A price ladder with traded delta, volume, pulling and stacking at each level, an order book, and a tape that merges venues and filters by size.
- Click on the ladder to place orders, drag them to move
- Prints filtered by size, so the large ones stand out
- Book and tape in coin or USD
One coin across every venue
An aggregated market sums the order books and heatmaps of a coin across venues, merges their tapes and footprints and adds up open interest.
- Choose which venues an aggregate includes
- One CVD line per venue: see who buys and who sells
- Each venue's own chart one click away
Paper and live trading on the chart
Trade where you read the flow: from the order ticket, the chart or the ladder, against the live book.
- Market, limit and stop orders, stop-limit and trailing stops, plus scale, TWAP and chase algos
- Paper accounts sweep the live book, wait in the queue and pay venue fees and funding
- Live on Hyperliquid, Binance, Bybit, OKX and Aster; keys stay on your device
- Positions, orders, take profit and stop loss on the chart; nine trading hotkeys
Flowscope Script and the Strategy Tester
A typed language for order flow. Write indicators and strategies, plot them on the chart and test them on real data.
- Subscribe to candles, volume delta, CVD, open interest, liquidations, funding, single trades and the book
- Plot into the chart, panes, tables and heatmaps, and raise alerts
- Backtests with commission, slippage and historical funding: profit factor, drawdown, Sharpe, monthly returns
- Diagnostics that say what is wrong and how to fix it
An AI assistant that works on your chart
Ask in plain language. It builds indicators and strategies, backtests them and reads the market, and you watch every step.
- Writes Flowscope Script, checks it and types it into the editor, then puts it on the chart
- Backtests strategies and improves them one change at a time
- Reads bars, the order book, large trades, liquidations and funding to answer about the market
- Uses your Claude or ChatGPT plan, or an API key; keys stay on this device
Everything in one terminal
- Charts
- 14 chart types, from candles to footprint and TPO. Time bars from 100 ms to weeks, tick, volume, notional, range and Renko bars.
- Studies
- 55 built-in studies: volume profiles (VPVR, VPSV, TPO), CVD and delta, open interest, funding, liquidations, VWAPs and the usual technicals.
- Positions
- Hyperliquid take-profits, stops and liquidation prices read from real positions; modelled liquidation levels on the other venues.
- Alerts
- On price, drawn lines, indicator values, large trades and liquidations, with sounds. Scripts raise their own.
- Sync
- Layouts, templates, alerts, paper accounts and scripts follow your account. Live trading keys never leave the device.
- Sharing
- Share scripts privately, by link or in the public library, and open layouts other traders shared.
- Browser and desktop
- The browser app is WebAssembly; the desktop app is the same Rust code with native GPU rendering.
- Performance
- Market state lives off the UI thread: 60 charts with heatmaps over 40 markets run on one machine.
Recorder
Venues do not publish historical order books. The Flowscope recorder runs the same engine around the clock, writes day files of footprints, candles and context, records Hyperliquid positions, and serves them read-only over HTTP to the desktop and browser apps.
