Where BacktestFlow leads

Built deeper for forex traders who trade by hand. The reasons to pick BacktestFlow, each with the mechanism behind it.

“AI-powered feedback on your trading behavior to identify patterns”

Source:FX Replay, product site

Both tools look for patterns in how you trade. Flow Coach keeps a pattern only if it passes a significance check, and its report may only quote numbers the engine measured.

  1. A record you cannot skip

    Every close opens a write up with notes, tags, your checklist and a screenshot captured on close. The replay waits until it is saved. So the trades you'd rather forget stay in the sample, and the statistics describe every trade you took.

  2. Findings that have to pass a test first

    Flow Coach runs 28 analyses across backtest and journal. A finding is kept only if it passes a significance check: a 90% Wilson interval and a minimum group of 8 trades. The written report may only quote numbers the engine measured; otherwise no report is issued.

  3. Execution, not just outcomes

    On every plan, the statistics compare the risk to reward you planned with what you captured, and track target hit rate and sizing consistency. On paid plans they also score checklist discipline. Those numbers separate a strategy problem from an execution problem. See the full list and why that distinction matters.

  4. Forex depth: pips and the session grid

    Statistics read in pips. Multi hour candles sit on the 17:00 New York grid through every daylight saving change, so they match tradingview.com. Switching timeframe rebuilds the current candle only from bars already replayed, so no future price shows. On paid plans, performance breaks down by trading session. More on the session breakdown.

  5. Your rules become the yardstick

    When you sign up, you describe your strategy in plain words and it becomes a strategy card with a checklist. Every trade is then measured against that checklist. On paid plans you can also draft it from the strategy form, or dictate it.

Where FX Replay leads

When FX Replay fits better. Where the job decides it.

  • You trade more than forex.

    If futures, stocks or crypto sit next to forex in your plan, FX Replay is the better fit: one platform covers all of them.

  • Your strategy lives inside a single candle.

    Scalping and very tight stops depend on what happens within a minute, and FX Replay's seconds timeframe shows it. For 15 minute charts and above, one minute candles are usually enough.

  • You work across several charts, or around the news.

    FX Replay shows several pairs at once and jumps straight to news events, with an economic calendar alongside. If your method depends on that view, it is the better fit.

The short answer

Which should you use?

If this is you

Choose FX Replay

You trade several markets, want replay below one minute, need several charts at once, or want to script your own indicators.

If this is you

Choose BacktestFlow

You trade forex by hand and want two answers: whether your strategy has an edge, and whether you followed your own process.

Both have a free plan, so you can test the same strategy on each before you pay for anything.
