LEARN & PRACTISE
How to backtest forex with candle replay
Backtesting lets you check a trading rule against historical prices. In ReplayPip, you choose a date, reveal one candle at a time and place simulated trades as setups appear. Here is how to run a practice session without looking ahead.
1. Write down the rules before you start
Specify the pair, timeframe, entry condition, stop-loss rule and exit condition. Keep the rules clear enough that you would make the same decision when you see the same setup again.
For example, a practice exercise might look for a close above a level you marked beforehand, with a stop below that level and a target at twice the stop distance. This is an illustrative exercise, not a recommended or validated strategy.
2. Choose a pair, timeframe and historical date
Open the replay workspace and choose EUR/USD, GBP/USD or USD/JPY. Use Change date to choose a point within the available history. Chart times are UTC.
Start with 1m, 5m, 15m or 1h if complete candles are available. The 1D button is disabled when the stored minute data cannot form complete daily candles. A disabled timeframe does not mean daily replay is a paid feature.
3. Reveal price without skipping decisions
Use Next candle for deliberate practice, or Play to advance automatically. Space toggles play and pause; the right arrow advances a candle when focus is outside an input or button.
Mark your levels before advancing. Drawing tools and indicators use the visible replay history. Pause when a setup appears and decide whether it meets your written rules. Do not adjust a rule simply because you have now seen what happened next.
4. Open and manage a simulated trade
Set a position size and optional stop-loss and take-profit distances. Buy / Long or Sell / Short opens a simulated market position at the revealed close. Pending entry lets you choose an entry level instead.
For a simple EUR/USD example, an entry at 1.10000, stop at 1.09800 and target at 1.10400 puts the stop 20 pips away and the target 40 pips away: a planned reward-to-risk ratio of 2:1. These are example levels to explain the controls, not a trade recommendation or an observed result.
You can also draw a Long Position or Short Position box, adjust its entry, stop and target, and place an order from it. The bottom trades table shows open, pending and completed trades. Orders and drawings do not send instructions to a broker.
5. Review the exercise and its limitations
Record the rule you tested, how consistently you followed it and the outcome. Keep your own notes before changing the pair, timeframe or date, resetting replay or reloading: the current version does not save your trades.
Repeat the exercise over different periods rather than judging an idea by one winning trade. Account for costs separately: this simulator does not model spreads, commissions, slippage, leverage or margin. Historical practice does not establish future profitability.
