EA Supply Demand
EA Supply Demand is an expert advisor (trading robot) for MetaTrader 4 from the Old Kings collection. Judging by its name, it is built around supply / demand zones.

It has 8 settings, for example Weak Area (default true), Untested Area (default true) and Verified Area (default true). Run it in the Strategy Tester and then on a demo account to see how it opens and closes trades. Inside: 1 EA file with source code (.mq4) you can open and edit in MetaEditor.
