Add code to close all orders at a specific hour of the day

[Thierry Waltrich Augusto]

Hello. I need to modify an EA that makes simple (orders one at a time) to be able to close all orders made by it at a pre-defined time (23h50). Any idea how to it? Maybe something like this? https://www.mql5.com/en/forum/139654

ps: I only started with mql5 two days ago, tried to implement it, but failed beautifully.

Thanks
