Unlike most people I've actually attached the EA. I don't know how anyone expects to improve their trading strategy simply based on the balance/equity chart when we know nothing about the logic of the trading strategy. Seems to work with EURJPY as well, not as good but still remains profitable. Main things I would like to improve is finding more trades and a better exit strategy mainly
