In this article I will show you how to create a simple AFL(Amibroker Formula Language) without manually coding or knowing any kind of syntax. This helps you to get an overview of building a basic AFL in few simple steps. Here is a video presentation that explains in detail for the starters who want to learn creating a basic AFL using the inbuilt AFL Wizard of Amibroker.
In this manner you can create AFLs to meet different criteria like macd, rsi, stoch, ema, etc with different periods and different values and different indicators. The list is endless!

thank you mame,
how to get the custom indicators in the AFL code wizard? we only get the defaults one, but i want the custom indicator also in it.
do guide me.
