Forex backtesting

Practice forex bar by bar before you risk it.

Pick a pair and a date, step the chart forward, and trade it on charts we built ourselves. When the run ends the session has its own stats, measured the way your real trades are.

The loop

Where forex backtesting sits

When the run ends the session has its own stats, measured the way your real trades are.

How it works

  1. 01

    Pick a pair and a date

    Choose the currency pair and where in history to start, then jump to the moment you want to study.

  2. 02

    Trade the replay

    Step forward one bar at a time and place entries, stops and targets as if it were live.

  3. 03

    Read the stats

    Win rate, expectancy and drawdown for the idea, with every simulated trade logged at its R multiple.

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
