Amibroker is considered as one of the most important tool for Traders. It’s widely popular across the globe and aids both discretionary and system traders. It comes bundled with a highly powerful backtesting and optimization engine, apart from the usual charting features. One can code custom indicators and also build a fully automated trading system out of Amibroker. In order to build a trading system through Amibroker you need to be acquainted with Amibroker formula language (Amibroker AFL). It’s a high-level programming language and very easy to understand if you start from basics. Even a person from non-programming background can learn AFL and avoid spending unnecessary on expensive ready-made AFL’s.

In this post, we’ll try to learn Amibroker AFL from the scratch with proper examples and downloadable code. I assume that you have already setup Amibroker in your machine and subscribed to live or Historical data feed. Also a basic understanding to Technical analysis and trading terminologies is a pre-requisite for Amibroker coding.
The codes in this and subsequent posts are copy-paste enabled. These are pretty straightforward and complexity will gradually increase. Feel free to comment if you are stuck at any point.
