Backcandle replays WIFUSD 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.
458 486 candles of Binance history are loaded, spanning January 2024 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.
Same engine, same hidden right-hand side — a different market's habits.
