May I ask why this is done?
int total=OrdersTotal();
Because while the loop is running, the value ofOrdersTotal(); may change and you may miss an order or the loop body will glitch
Alexey Kozitsyn:
I want to add, if there are a lot of orders, at each iteration of the loop, thefunction will be called, and it's not economical.
Are you both joking or for real?

Alexey Kozitsyn:
У Вас другая точка зрения?
int i=OrdersTotal()-1
This action is executed once before the first iteration. There is no point in adding anything else. You just make the code larger.
in this design is possible, but in this design there is a chance of a glitch

:)))))))
On what grounds?
А.
So always go over from the end.

Yep, so it's just a matter of logic. I was more concerned that apart from the order of actions, you also have to take into account the update time of the data on the server.
I finally figured out what it was all about))))))))
As usual, ridiculously simple))
It's just a wrong application of pending orders) price went lower and the limit order with the buy price was higher))) It just couldn't be placed under those conditions)
Added "stop order" setting and voila, everything is as it should be))))
This method is not always suitable. For example, if you need to overshoot starting with the earliest order.
