Дмитрий С:
Good morning! How can I implement displaying high and low bar data on a chart? And to highlight the same colour.

By using, for example, an indicator.

[Dmitri Custurov]

int file=FileOpen("expert.ex4", FILE_READ|FILE_BIN);

Trying to open EA in binary form. It returns -1 and error 5002. Is it at all possible to open files of this type?

Good afternoon. Can you tell me why the stop and take on the ATR is not working!

Yes! It will look like this!

[Dmitri Custurov]

I know it will look like this, but the code returns an error as I wrote above. That is - it doesn't open. File handle returns -1 and error 5002 - invalid file name. All text files, pictures opens fine, all ex4/5 and dll does not open.

Did you try to change the extension?

Removed the extension - that's how it works. Apparently it's some kind of protection from the developers. Don't know why though.

Fight against decompiling most likely.

Valeriy Yastremskiy:
Fighting a decompile is more likely.
