hi everyone,im new into coding and i have created several EAs using a 3rd party software, and i also optimized them too using the same software. How ever i have a problem. after exporting the EAs to MT4 i discovered that te EAs cant be optimized on MT4. and some of them that can worked on on the 3rd party software are not working on MT4, All i want to do is to be able to do make the EAs work, optimized and backtest on MT4.
