i read so many posts people are going live with Your_Lucky at alpari because alpari demo has good performance.
Be aware that alpari live at asia session EG has 5p spread, so Your_Lucky will lose your money.
Open a live account, wait for GMT 21.03 (then alpari rises spread). Enter backtester and check spread (symbol-button). If spread is 50 (5-digits) then you can run backtester and try to optimize settings.
Do not make backtests before 9/2008, because market changes at beginning of september and you will optimize ea for the wrong market conditions.

Good Luck,
