yes, you can check few conditions (how much you want) and then you can decide in your expert what strategie you use
how do i start an expert from mql4 from another expert?
what is the command
This is not a good idea.
You will end up having to write and call external modules to unload and load EAs etc.
Complexity = high. Reliability = potentially low.
The way I'd do this would be to take a modular approach to your EA and to build the following:
- A parent EA (including the init, start and deinit functions) which checks the conditions and decides the strategy
- A collection of modules, each built as a function (or function set) which delivers a particular strategy (included in the parent EA as header files)
- A collection of modules, each built as a function which delivers a common service - either to the strategy modules or to the parent EA - (also included in the parent EA as header files)
