If you need to close 0.3 and then 0.7 from the 1st lot, it is easier to open two orders with different takeoffs.

This is not convenient, in my scalp system you have to actively tactically follow the trades. + there can be impulses, and to open from different windows or to change a lot in seconds is such an activity :) It is easier to open 1 lot, and then partially fix. But do not fix manually, but by given price levels (price). If you work with 3 Takei, you will have to play the piano when opening deals.

Then order yourself an Expert Advisor

So there are no ready-made ones? Okay. (chuckles) How much would an owl like this cost?

works correctly.

The repetitions are removed from the array. In owt, if array.

int arr[]= {6,4,6,7,9,65,66,2,2,9,7,7};

is dynamic and it increases, also works correctly, but if it decreases, it starts to lie.

[Aleksandr Kononov]

Hello all, Mr. experienced developer, could you please advise a beginner? I am interested in the process of packing MQL4 Expert Advisor in one ex4 file for uploading to Market if I have a custom indicator connected through iCustom (and the indicator itself is also connected to another indicator, and the latter in its turn is a library). I wonder if there is an easy way to move all this stuff to one file or will I have to integrate everything directly in the EA code?

ENUM_POSITION_TYPE type = PositionGetInteger(POSITION_TYPE);

Why does the compiler give the implicit enum conversion warning ?
