Backcandle replays SOLUSD one bar at a time. The chart advances on your keypress, not on a clock, and everything to the right of the current bar stays hidden — so you practise deciding without knowing how the day ends.
1 023 944 candles of Binance history are loaded, spanning September 2020 to October 2026 across 6 timeframes (5m, 15m, 30m, 1h, 4h, 1d). Orders, fills and funding are simulated against those bars, including the weekends this market never closes for.
Written up, dated and ready to replay — each one drops you in before the move, with the outcome hidden.
Same engine, same hidden right-hand side — a different market's habits.
