Jump to time ## Straight to the release, or the session open. Jump to an NFP print, a London open or the setup you remember, instead of scrolling through hours of quiet range. - Any date, any session - The future stays hidden until you step into it - Your drawings stay on the chart Session stats ## The stats of the idea, when the run is done. Every simulated trade is logged with its R multiple, so a session ends with numbers rather than a feeling about the pair. - Win rate, expectancy, drawdown - Per-trade R and equity curve - Unlimited sessions on Pro Rules ## Check the session against the strategy you wrote. On Plus and Pro a session links to a strategy in your Playbook and every simulated trade is checked against its rules, so the stats at the end belong to the strategy, not just the run. - Link a session to a Playbook strategy - Rule checks on every simulated trade - Edge suggests what to test next DT Passport ## Numbers you can trust.

Real historical candles for the forex instruments in the app, and coverage grows as data partners are added. The charts are ours rather than an embed, so the replay, your drawings and the simulated fills are all in one place. ### Is forex backtesting free? A free account gets 2 full sessions, up to 50 trades in each, on 2 market at a time. Plus keeps 3 sessions at a time, and Pro removes every cap. ### How is this different from bar replay on a charting site? A replay on a charting site ends when you close the tab. Here every simulated trade is logged with its R multiple, and the session has stats you can set beside your live record. ### Can I test my strategy against its written rules? Yes. On Plus and Pro a session can be linked to a strategy in your Playbook, and each simulated trade is checked against the rules you wrote down. ### Do backtests count toward DT Scholarships? Yes. A completed and reviewed session is one of the three things the application asks for, beside ten logged trades and a 14-day logging streak. ## Test the pair before the money is on it. 2 sessions are free. Bring a setup you believe in and find out.
