No, only "loaded successfully" and "removed".

Yes, saw it, tried your code to load, there's a stack overflow by

2019.03.26 19:38:16.053 Stack overflow

tried to move globally described variables in the OnStart() section did not help, maybe somewhere in the code you have a large amount of data, you need to understand what you're doing, and the code is not optimal written, I can not so quick help

Karoche I missed this in the log, my script uses large arrays of double (3 arrays of 864000). Reduced by 10 times, all works, I'm at a low level is not versed, tell me what kind of iron needs to pump in order for such things to work, just add RAM? I certainly will not buy a special for the prog, I'll rewrite it, just wondering.

3 x 8 x 864000 = 20736000 bytes

this is too much, mt4 is 32 bit, i don't want to search for information, but i think 32 bit programs have 2 gb memory limit

My device has nothing to do with it.

ZS: recalculated 20736000 bytes is 20 Mb, not much in principle, probably you have statically described arrays, try to change to dynamic arrays and then resize, maybe it will help - I have not read for a long time how memory in MT is allocated, but the script was crashed because of stack overflow - somewhere the memory is much reserved

How to create an array via new so that it will be written in chem? I only understood how to create a class with an array in the field, but it would be weird to use it, in c++ it looks like this: int *array = new int[n]; It doesn't work here.

double x[];
ArrayResize(x,1000);

Can you tell me how to display the ASK price five characters after the point in Print instead of four?

Print("Ask: ",DoubleToString(Ask,5));

There is a date of e.g. 26.03.2019, how can we calculate 3 days from this, so that 23.03.2019 would appear in the Comment?

ponochka:
Date 26.03.2019 for example, how to convert it into 3 days, so that the Comment would come 23.03.2019?

Date-3*PeriodSeconds(PERIOD_D1);

You're the one who took 24 hours.
