Markets open hours after holidays while backtesting

It's not a huge problem to me, but eats some efforts to aviod.

When backtesting I see big difference in results if starting date is holiday or the first day after holiday.

For example, 01/11/2020 is sunday, markets are closed and when backtesting begins from 01/11/2020, markets seem to be open at 02/11/2020 01:05:00.

If backtesting begins from 02/11/2020, it seems that markets are open at 02/11/2020 03:00:00.

Thus in the two cases backtesting starts from different prices and obviously gives different results.

Can you explain how can I solve this? I'd prefer if it wouln't make difference what date I choose for the beginning of test. The first price should appear at the same time and of the same value.

PS: TimeZone = TimeZones.RussianStandardTime

Thanks in advance. cTrader is the best!
