Hi, I coded a multi-symbol EA and use it for Forex pairs. For Money Management you can choose between either fix lot sizes or risk adjusted lot size. I would like to extend the code to run the EA with other instruments like stocks, indices and commodities, simultaneously. For this I do check the lot size calculation based on the specification for each instrument (min, max lot size, lot step, etc.). What is your opinion? Do you trade different instruments in one EA or do you have different EA for different instruments? What are the pros and cons?
