Backtesting
Backtesting means evaluating a trading approach using historical market data instead of live markets. ReplayBureau does this through manual, candle-by-candle market replay with a simulated account.
How backtesting works in ReplayBureau
- You start a session on a chosen instrument and historical start date.
- The chart shows only candles up to the current replay point. You decide when to move forward.
- You place and manage simulated trades as the replay advances, then review the results.
Simulated order management
- Market, limit and stop orders.
- Stop loss and take profit.
- Partial profits and breakeven (Essential and Plus).
- A configurable spread and starting equity for each session (default equity $100,000, minimum $5,000).
Navigating history
- Play, pause and step through the replay and change the playback speed.
- 10 timeframes from 1m to 1D.
- “Go to” a chosen date (Essential and Plus) or the next New York, London or Asia open (Plus).
Measuring results
- Win rate and long/short split on every plan.
- Essential and Plus add all statistics, an equity curve and a daily profit and loss calendar.
- A Monte Carlo simulation can be run on a session’s closed trades. It requires at least 30 closed trades.
- Every trade can be journaled with notes and tags.

Limitations
Backtesting results are hypothetical. Historical performance does not guarantee future results.
Real markets can differ from a simulation because of factors such as liquidity, execution delays, transaction costs and slippage.
ReplayBureau is a simulation and analysis tool, not a broker. Simulated balances, profits and losses are not real money, and backtesting or paper-trading results do not guarantee future performance.
