ExampleWhen you run backtest on cross pairs, the tester uses the main symbol and an additional one allowing to convert the profit currency of the main symbol to the account currency. Access to the additional symbol, generation of its ticks, and synchronization with the main symbol take too much precious computing resources and time during a single test run and especially during optimization. However, this accuracy is almost always unnecessary. Therefore, I wanted to bypass this obtrusiveness/flaw of the MetaTrader 5 tester. It can be easily done in MetaTrader 4, because it provides the possibility to change the account currency directly in the tester. MetaTrader 5 does not provide this option.
