Add modules (Stop Loss/Trailing Stops) to your existing AFL.

: The ultimate verification. This tests the AFL code on "out-of-sample" data (data the code hasn't seen yet) to ensure the strategy isn't just "curve-fitted" to the past. 3. The Climax: The "Verified" Milestone

Use IIf() (Array If) for array calculations: Color = IIf( Close > Open, colorGreen, colorRed ); Step C: The "Empty Database" Test

Contains explicit rules for entry, exit, position sizing, and risk management. 2. Common Errors in Unverified AFL Code

If you are looking to audit your script further, could you share the you are using, your intended execution timeframe , or the specific error codes you are seeing? Knowing these details will help pinpoint the exact updates needed to get your AFL strategy verified.

: Clean Plot functions for manual verification on charts. How to Self-Verify

Steps:

Run the script through the modern, multi-threaded engine available in AmiBroker 7.00 or newer. This test searches for logical memory leaks or resource deadlocks across multiple hardware cores. Multi-Asset Explorations

Repeated identical buy signals over sequential bars skew simulation metrics and exhaust API memory during execution.

Notice how the verified version explicitly zeros out all action arrays at the top of the bar.

Plot your strategy signals visually on a chart. Cross-check the buy/sell arrows with the mathematical conditions to ensure they align perfectly. Step 4: Run a Monte Carlo Simulation

SetChartOptions(0, chartShowDates); _SECTION_BEGIN("Trading Logic");

Verified AFL code doesn’t just backtest well on one stock or one time period. It has been stress-tested for walk-forward analysis, Monte Carlo simulation, and out-of-sample robustness. True verification includes a performance report that explains why the strategy works, not just that it worked.

By instilling a rigorous verification protocol into your AmiBroker workflow, you protect your capital from programming bugs and ensure that your automated edge functions exactly as intended in the live market.
