Replay the market
tick by tick.
Backtick replays Binance history candle-by-candle and trade-by-trade — with a real bid/ask tape, footprint, and hypothetical trades — so you can practice discretionary reads against how price actually printed.
No sign-up to try. Your trades stay on your machine.
Order-flow tools, without the paywall
The reads that other platforms gate behind premium tiers — built in, accurate to the raw exchange data, and open for you to inspect.
Open source & local-first
MIT-licensed, runs on your own machine, and reads straight from Binance. No account required. Your hypothetical trades stay on this device; export a backup to move them elsewhere.
MIT · self-hostableTrue time & sales
Every print tagged buy or sell from Binance aggTrades' real is_buyer_maker flag — green for aggressive buys at the ask, orange for sells at the bid — with a percentile highlighter for large prints.
Tick-by-tick replay + synced tape
Step or auto-play individual aggTrades as the forming candle rebuilds in real time, with the tape streaming in lockstep. Scrub from 1× to 200× to feel how a move actually developed.
