Basic Building Blocks

Every robust AmiBroker AFL code consists of three potential sections: AFL includes an "Optimizer" that allows traders to

6.1 The _TRACE() Function

Prints values to the log window (View -> Log).

1. Robust Out-of-Sample Testing: Never trust an optimization that doesn't have a 2-year forward test.
2. Transaction Costs: Always include SetOption("CommissionMode", 3); and SetOption("CommissionAmount", 0.01); for $0.01 per share.
3. Slippage: Use SetTradeDelays(1, 1, 1, 1); to simulate next-bar execution.

AFL includes an "Optimizer" that allows traders to find the best parameters for their strategies (e.g., finding whether a 10-day or 20-day moving average works better). However, AmiBroker emphasizes the importance of Walk-Forward Testing and Monte Carlo simulation to ensure that the strategy is robust and not merely "curve-fitted" to historical noise. Conclusion
