Pyro:

Can you please tell me how to check the validity of an order? For example, I have a pending order in place and need to check if it has triggered a stop order.

bool check=OrderChek(ticket);

Comment("The order with the ticket ", ticket, "does not exist (triggered)");

I can't find how to do this.

OrderCloseTime

Sergey_Rogozin:
The function looks like this

That is, if there are open positions, the function will detect them and return true.

Your task is to put something like this before OrderSend(.......):

Yeah thanks))

Can you tell me why, when I insert a line in the EA

Comment (High[Bars-1]);

and run the Expert Advisor in the Visual tester - it prints the same value despite the fact that bars are changing ?

paibolit ,Bars is the number of history bars, it is set in the settings.

Put a specific bar number, for example, High[ 3 ] and you will get changes.

You have taken the very first bar in the history and it, in turn, remaining always the first one, gives you the same value.

This is my first experiment with bars - thanks for the normal explanation

I have two simple topical questions, who knows, please answer me!

do not understand why

HighesBuffer[i]=MathMax(HighesBuffer[i],High[k]); //if(High[k]>maximum) maximum=High[k];
 LowesBuffer[i]=MathMin(LowesBuffer[i],Low[k]);   // if(Low[k]<minimum) minimum=Low[k];

it's not the same as

if(High[k]>HighesBuffer[i]) HighesBuffer[i]=High[k];
if(Low[k]<LowesBuffer[i]) LowesBuffer[i]=Low[k];

you can create functions with optional parameters. can i make a function that returns the sum of values passed to it, so that their number is unlimited? or at least limited, but large)
