Have you done anything yet to assess whether the system is robust, do you actually know how the EA works and how it was developed?
It is not possible to say anything about that just by looking at this stats.
Is the premise of the system heuristic and fundamentally repeatable?
All systems are optimized to past data to some extent to try to fit past patterns, the crux is whether it is overfitted.
Does the EA work as well when parameters are varied slightly?
Do you know when the EA will do well and when it will not do well?
I think it is important to test your EA over as much data as possible, even though there might be parameters drifts over long periods of time, because that will tell you when and why your EA did not work over that period. Then ask yourself is there a fundamental reason why.
Dukascopy intraday data goes back as far as 2003, it does not cost you anything to test your EA on it. There are minor bad data though during early periods.
There are whole books written for systems development, they should answer some of the dilemmas or perils a systems trader and developer will face.
