Performance of EA with different settings.

Hello,
I had run Ea with some changed in its settings. I think default settings are best. However you may increase your profit with your involvement in the market by checking the economic calender. By checking market conditions one may improve his profit by the trading forex. I made $1000 within 1 month with Aeron EA. My initial deposit was $4000.
I changed following settings
MaxTrades=5
FreeMarginForAutolots=2
Also time to time I checked the economic calender to change my EA settings accordingly. I think I may earn more with some more aggressive settings. Thanks
