Aleksandr Nekrasov:
If the MT 5 terminal in the market review has indicative instruments, such as stock indices, and there are no current bid ask indicators, will they be analyzed in the Expert Advisor to check the strategy?
You can analyze, of course, what is there. There are no prices, apparently due to the fact that these instruments have a limited session compared to the rest. Within the session, prices should be. Well, there are always history bars.

As far as I know, the tester works according to the rules of your trading environment. If the properties of the symbols indicate that trading is prohibited, then the tester will not open transactions on them. But this does not prevent you from analyzing their prices.
And what is the point of testing indicator trading if it is known that it will not work online?
