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.
