@saeed-2 I think the link below should work just fine for what you asked. I haven't had a chance to test it.

You need to create two variables as below.

@saeed-2 If you tell me exactly the levels that you want I can write something for you. Just le me know, for example:
0 to 200 --> 0.02 lots
200 to 400 --> 0.04 lots
400 to 600 --> 0.06 lots and so on.
Just let me know and I will try to help you.

@saeed-2 I think you can do all that using a custom MQL code with a few if statements.
You test the account balance and if between the amounts that you want you return the value that you want to your lots size variable.

Something like
if account balance >=200 && <400; Lot_Size=0.05 and so on...

Hope that makes sense.

Good afternoon.
You can find some information on the links below.
Check both of them and try a play around with it.
If after that you have any specific questions bring them on, myself, I will be happy to give you some support.

@provinccigomes If I will have some spare time during the weekend I will try to draft something and share it with you.

@l-andorrà Let me see if I have some spare time during the weekend and I can try to draft something. At the moment I'm a bit busy fighting to build my own EA.
I will let you know if I can achieve anything.

I do not know the exact answer, but I would guess that you have to many conditions and with very close periods. Visually, for example, on H1 timeframe it could seem that all conditions are met, however because they are so close to each other that can mislead you.
Share your project and I will try to help.

@padletut
Any idea why that is happening?
