About Array Memory

New comment
 

hello guys.

I got a situation that when my EA open new order, Order Open Price will sort in Array. However, when order closed, that Open Price still in Array(e.g BuyOrderOpenPrice[0]).

I tried ArrayRemove, ArrayFill, ArrayResize etc, but not work. Does anyone know how to clear array memory after order close? Thanks.

To help you, you must show your MQL5 code.
