Thank you for the confirmation of my choice about MT4 as 2 fxdreema veterans also shares the same view about MT4 is the better choice (also the same view with old school programmers), I will try to optimize blocks to reduce lines of coding.
FYI, I manually put a lot of input to get the total of around 200,000 lines of code but the EA can be compiled with ease so the problem is not about the limitation of number of lines of code in MT4.
Thank you !!!
