Backtest & replay
Practice on yesterday before risking tomorrow
Bar replay on any symbol with paper-account persistence — every practice fill lands in the same analytics as your live trades, so you can measure a setup before you fund it.
Any symbol, bar by bar
Step through historical bars at your own pace, placing entries, exits, and stops as if it were live.
Paper accounts that persist
Replay sessions record to a paper account — kept apart from live results, analyzed with the same math.
The same analytics
Expectancy, MAE/MFE, and session breakdowns work on replay trades too — a backtest you can review like a journal.
Monte Carlo on top
Project a strategy's drawdown and variance with the Monte Carlo simulator built into Reports.
