Here is a comprehensive guide to verifying your AmiBroker AFL code to build robust, production-ready trading systems. 1. The Core of AFL Verification: Syntax vs. Logic

IIf() handles arrays , not strings.

The interface is often described as looking like it’s from the 1990s. amibroker afl code verified
