Could it be some kind of delayed error? The programme reaches the end and then hangs, is this possible?

[Aleksandr Kononov]

The problem is in the loop after all. The Comment is running late. Print is the last in the loop

Can you tell me how to find an arrow among other objects in mql4? I need to delete all arrows and leave the lines

Well, read the documentation

int  ObjectsDeleteAll(
   int    sub_window=EMPTY,   // индекс окна
   int    object_type=EMPTY   // тип объекта для удаления
   );

Thank you!

Good time to know mql4. There is a function that closes the percentage part of the furthest losing order in the series due to profitable positions of any direction. I need help in improving this function! Namely, we need to partially close all remaining orders in the series (due to profitable positions of any direction) instead of the first one. Thanks in advance!

Good time to all mql4 users. We have a function which closes the part of the furthest losing order in a series by percentage points at the expense of profitable positions in any direction. We need help in finalizing this function! Namely, we need to partially close all remaining orders in the series (due to profitable positions of any direction) instead of the first one. Thanks in advance!

I have been strugglingwith this function for about 2 months. There are so many nuances. Especially this line

 ProfitPer=OrderProfit()+OrderCommission()+OrderSwap();//ПРОФИТ ОДНОГО ОРДЕРА

When there are a lot of orders in the grid, it gives a total loss when it closes, although it should close all of them at zero. I ended up removing commissions and swaps altogether

double spreadLoss =(MarketInfo(_Symbol,MODE_TICKVALUE)* MarketInfo(_Symbol,MODE_SPREAD));

[Aleksandr Kononov]

And then in the function you can multiply by lot/lotstep for each order, but I just made a multiplier

[Aleksandr Kononov]

And before OrderClose() they forgot (!)

Good afternoon. Could you please advise how to pay for MQL4 services due to the current situation?
