1. Check the connection to the server - maybe your demo account is already out of date and you need to create a new one
2. F2 and download all the necessary history by timeframe for the desired symbol.

Well, that's a hell of a wrap. You have to give up the black box to work together. If the account is the same, the history and open trades will be available. If the accounts are different, the signals may help. These trades will simply work for them as well.

Thank you.

How do I get the previous (penultimate) price? Bid, ask. Apart from the obvious way of keeping a tick with the arrival of each new one, is there something?

It needs the previous Bid/Ask, not the closing/opening :)

In mql4 it is only to memorize. In mql5 - CopyTicks()

then download to the code base some ready-made code that writes ticks.
