Snest:

It's been three months and the ticket still hasn't been closed. Trouble.

Write to them again in the application and ask them to comment. Generally sad, of course, but I also occasionally catch ticks of uncertain direction.

Does AMP already provide reals for MT5? Have they opened online?

The question is not for us, but for datafeed, which was not written by us.

Snest 2017.07.12 19:55 #373

Yes, opened a real from AMP on MT5.

Renat, is it the wrong quotes from CQG?

Do they provide the wrong trade direction? Or they don't provide it at all for MT5 and have to determine the direction algorithmically?

Does it make sense for me to compare quotes with another terminal on CQG?

The result presented by you is not a bug of the CopyTicks function. CopyTicks gives exactly what is in the ticks database.

Why there are such backups in the tick database (exactly backups, not duplicates, because the time is different), we're trying to figure out
