Cannot Back Test on Daily Charts

[[Deleted]]

Hi,

I have an EA designed for daily charts. I have downloaded all history of the EUR/USD. I have also set the number of bars to 9999999999999999. I close MT4 and open it again after downloading all history of EUR/USD.

When I run my strategy tester, it does not run even 1 bar in the visual mode. I left it overnight and it wiped out my hard drive space.

Any ideas why this is happening?
