Amibroker Afl Code — Verified

// Variables MA_Fast = MA(C, 50); MA_Slow = MA(C, 100); RSI_Val = RSI(14);

Exploration allows you to view your variables in a spreadsheet format. This is the standard for verifying backtest logic.

Use the built-in or systematically shift your historical data forward by 10 bars. If your historical entry signals move with the shift, your code contains look-ahead bias. Step 3: Implement the BarIndex() Safeguard amibroker afl code verified

Run a backtest and open the generated trade list. Compare the execution price shown in the report against your chart's actual price values for that day. If the report says you bought at $10.50, but the asset's low for that day was $12.00, your entry price logic is broken. Adjust your BuyPrice variable definition to fix the mismatch. Summary Checklist for Verified AFL Code

The code matches your broker's actual execution rules, accounting for realistic slippage, liquidity, and trading fees. 2. Setting Up the Verification Environment // Variables MA_Fast = MA(C, 50); MA_Slow =

// Verified PositionScore = IIf(Nz(RSI(), 0) > 0, RSI(), 0);

// This prints to the Log window when you click on a bar where Buy is true printf("Buy Signal Date: %s, Close: %g, MA Value: %g", DateTimeToStr(SelectedValue(DateTime())), SelectedValue(C), SelectedValue(MA(C, 20))); If your historical entry signals move with the

True verification requires checking multiple layers of the script. A verified status means the code has passed tests in four specific areas. 1. Syntax and Compilation

Verified AFL code is not optional for serious automated trading. This paper provides a : static analysis, runtime assertions, repaint testing, and execution fidelity checks. By applying these methods, a developer can eliminate the most common sources of backtest overfitting and live-market failure.

The code must work across multiple timeframes (e.g., 5-minute, hourly, daily). It should handle different asset classes like stocks, forex, and futures without crashing. 4. Order Execution Safety

: The code now includes robust risk management, like PositionScore to rank trades and ApplyStop for automated exits.
