I note some of signal provider (e.g. https://www.mql5.com/en/signals/137963), the signal start at Apr 2015, but the equity chart record is recorded from 10 Oct 2015 afterward. The past record is missing.
Does it mean that I can delete the past record in my MT4 account ? How?
Mql5 just show after the signal go to public. The past can not be shown. That is why dd is low. Many signal trade long but just go to public recently due to this.
