Forex Diamond is famous for bundling three strategies in one EA. From a coding view, that is an interesting architecture. Here is how it works and where to get source to build something similar.
The strategy in code terms
A multi strategy EA runs separate logic modules (trend and retrace, countertrend, scalping) and decides which is active based on market conditions. In code this means a clean structure where each module has its own entry, exit and risk, plus a controller that switches or blends them.
What to study in the source
- How the modules are separated (functions or classes per strategy).
- The condition that selects which module trades.
- How risk is capped across all modules at once.
