Im didnt really have any mentor in coding field or ever really take computer science in highschool... Ive been coding by having Chatgpt explain to me stuff.

Yeah not great. But hey I did have few bots that work. It just... doesnt run well. not in signal sense but in EA system management. Sooooo..

Can everyone explain to me the ex5, mq5 n mqh files purpose and limitation please. Chatgpt awfully keep telling yes and no with the same question with different chat..

So I seriously need help. the thing that I need to know is these thing but it would be helpful if you can add more:

1. does sharing mqh file with multiple ex5 would conflicted memory? 
2. what you "shouldnt" do in mqh.

3. what you shouldnt do in mq5.

4. what limitation on mqh same with mq5. 

honestly if there a documents explaining it, please refer to me as well. I try to search it but it feel like... Ive just playing maze games...


thanks.

For the long but wise road of learning, see MQL5 Reference – How to use algorithmic/automated trading language for MetaTrader 5

To slap an EA together quickly, see:


                                                     
 

You compile the MQ5 to create the EX5. The terminal runs the EX5.

MQH files are text files, containing partial codes. You do nothing with them.

MQ5 files are text file, containing the actual code. In the MQ5 file would be an #include statement. During compilation, the statement is replaced by the include file, just as if the contents of the include file were actually at that point.
