Saw now that you've added a log. Here you have duplicate messages too :)

If you look at the time, you will see that nothing is duplicated, it only prints on a new bar when there is a signal

законопослушный гражданин:

can you please explain the difference between the functions?

for (int j = OrdersHistoryTotal()-1; j >= 0; j--)

{

if(OrderSelect(j, SELECT_BY_POS,MODE_HISTORY))

и

int i=OrdersHistoryTotal();

for(int pos=0; pos<i; pos++)

{

if(OrderSelect(pos, SELECT_BY_POS,MODE_HISTORY))

No

Because you have Print() only in OnTick(). Put it in each condition in isCrossing()

No

Well, not exactly. One cycle from the beginning of the list, the other from the end.

No

both functions "fetch" closed orders from the history ?

You're right, I didn't pay attention to the order of the loop, I only looked at the definition of OrdersHistoryTotal()

Yes, but one from the beginning of the history and the other from the end.

Yes, but one is from the beginning of the story and the other from the end.

Thank you. Did I get it right, this function "goes through" from the end?

int i=OrdersHistoryTotal();

for(int pos=0; pos<i; pos++)

{

if(OrderSelect(pos, SELECT_BY_POS, MODE_HISTORY))

This one searches from the zero index, i.e. from the beginning.
