Bar replay is a charting feature that plays historical price data forward one candle at a time, hiding the future so a trader can practice entries, exits, and trade management on past markets as if they were unfolding live. It is manual backtesting at fast-forward speed.
Replay solves the central problem of practice: sample size per hour. A setup that appears twice a week live can be found dozens of times in an afternoon of replayed sessions, and because the future is hidden, every decision is made under genuine uncertainty — unlike scrolling back on a chart, where hindsight quietly grades every setup a winner.
Replay results still exclude live spreads, queue position, and real-money emotions, so it complements rather than replaces forward testing. Secuora’s bar-replay backtester runs in the browser with a free no-sign-up demo at /backtest/demo, timeframes from 1 minute to 1 month, and simulated orders with stop-loss, take-profit, and partial closes.
