[Title Suggestion]: Verified AFL Trading Strategy – [Insert Strategy Name, e.g., EMA Cross with RSI Filter] 1. Strategy Overview

[Briefly explain how the code works, e.g., "This strategy enters long when the 50-period EMA crosses above the 100-period EMA while the RSI is above 50"]. Timeframe: [e.g., 5-minute, Daily, Weekly]. Asset Class: [e.g., Equities, Forex, Indices]. 2. Verified AFL Code Always use code blocks ( ) when posting on the AmiBroker Forum to ensure it is readable and easy for others to copy.

1. Introduction

Quantitative traders often treat backtesting as a gold standard. In reality, a backtest is only as reliable as the AFL code that generates it. Verified AFL code means:

  1. No forward-looking information – signals use only historical data.
  2. No repainting – signals are stable after the bar closes.
  3. Consistent trade execution – fills respect realistic delays and prices.
  4. Reproducible results – the same inputs produce identical outputs.

This paper avoids abstract theory and focuses on verifiable code constructs, test harnesses, and debugging patterns specific to AmiBroker.

The Bad (Cons)

| Aspect | Detail | |--------|--------| | False confidence | A “verified” code can still be a losing strategy. Verification ≠ validation. | | No look-ahead check | Many cheap verifiers miss Ref(..., -1) mistakes or StaticVar abuse. | | No optimization ethics | Verified code may still be curve-fitted to past data. | | Vague scope | Most services don’t define what “verified” includes – you may pay for just a syntax check. |
