Andrey Dik:
in the CopyTicks tester returns zeros, is this normal?

Are you testing, by any chance, in OHLC M1 mode or opening prices?

No, I've tried both "ticks" and "real ticks", sometimes the structure array is full of zeros, sometimes partially.

Please, someone try this EA in the tester in different test modes:

The point of it is to get a specified number of the freshest ticks on each tick. zeros come out, for crying out loud.

I managed to get it on FORTS, but only a TRADE-flow (using an indicator). Your Expert Advisor does not even want to run on real ticks...

yes, there is a problem. but where? what exactly is the problem, that is the question.

But one time there was an error.

Well, if you want the freshest ticks, you should not take them from zero, but from the current time in milliseconds.

    received = CopyTicks (symbol, ticks, flag, TimeCurrent()*1000, count);

Alexey Viktorov:

The help says:

from

[in] Date from which the ticks are requested. Specified in milliseconds from 01.01.1970. If from=0, the last count of ticks is given .

I save mq5-file in Metaeditor, but its old version is saved (time varies). In this case ex5 at compilation corresponds to what I see in ME. But when I close ME, all data in file will be lost.

Trying to save it under different name - file is created, but there is old source - not the one I see in ME. There is definitely room on the drive.
