Backtesting app guide
A backtesting app for traders who need clean reps
A useful backtesting app should help you make decisions before the outcome is visible, record those decisions, and turn repeated practice into reviewable data.
Quick takeaways
What this page covers
- 01A serious backtesting app should center the chart, not bury it.
- 02Replay keeps practice honest by hiding future candles.
- 03Automatic journaling makes repeated review more reliable.
- 04Candlune combines replay, markup, simulated trades, and analytics in one workflow.
Workflow diagram
The replay-to-review loop
Each session should move from chart context to a logged decision, then into a review that tells you what to repeat or fix.
- 01Load a session
Choose a focused historical market window instead of browsing a finished chart.
- 02Mark the setup
Draw the level, zone, or invalidation before the trade result is visible.
- 03Take the paper trade
Enter, set risk, and let the replay expose whether the decision held up.
- 04Review the pattern
Use the journal and dashboard to find the next behavior to practice.
The chart has to stay first
Backtesting software can become crowded with dashboards, reports, and settings. Those are useful later, but the practice session still begins on the chart.
Candlune keeps the chart screen central because manual backtesting depends on reading price action, marking levels, and making a decision without hindsight.
Replay beats finished-chart review
A static historical chart is easy to interpret after the move has happened. The better test is whether you could identify the setup while the next candle was still unknown.
A replay-first app gives you that uncertainty. It reveals the session step by step, so your journal records the decision you actually made rather than the story you built afterward.
- Step candles forward at your own pace.
- Draw the level or zone before entry.
- Place the simulated trade before the outcome.
- Review the result without rewriting the reason.
The journal should be automatic where possible
A backtesting journal is only useful if it is complete. Manual typing can work, but it often breaks down when you are tired or moving through many sessions.
Candlune logs simulated replay trades into a journal automatically, then lets you add notes and setup context. The app should reduce admin work without replacing your judgment.
Analytics should answer practical questions
Win rate alone is not enough. A useful review tells you whether losses cluster around a setup, session, timeframe, or behavior mistake.
That is why Candlune connects replay trades to dashboard metrics and a daily performance calendar. The goal is to see what to practice next.
Backtest with a cleaner loop
Use Candlune to replay historical XAUUSD candles, take simulated trades, and review the journal that gets built from those decisions.
