Backtesting

A backtest is a trace, not a promise.

Strategy Lab runs the validated spec over local historical candles. It simulates buys using explicit fee, slippage, and execution timing assumptions.

The result shows what happened under those assumptions:

• when cash entered
• which rules fired
• which branch was selected
• how much cash was requested
• how much was actually spent
• what cash remained
• how the portfolio value moved

This is why the result path matters more than a single return number.
