Also, what was the developer theory of why the EA can be consistently profitable. You see, you use your own understand of how you think the market moves daily and how you can profit from them repeatedly. This is why I believe to design an effective system, a trader needs to have some understanding of why he/she believe the system will work based on the person understanding of the market. That's The biggest problem I think with trading system design is finding that have good odds of making money in the future. The irregular markets behavior during the session can be reduce by reducing the amounts of trades per session. I just 1-2 trades per day, then let big boys do whatever they wanna do.
