signal data analysis

 
I have an account started on May 2019. The relevant mql5 signal seems to start on March 2020. Is it possible to extend the analysis to the beginning of the account data?

You should have connected your trading account as a signal from the very beginning.

There is no way to detect certain aspects of a trading account as the maximum drawdown, when it is not connected to a monitoring system from the very beginning.
