Different results with strategy tester (depending if you logged in via live or demo account)

[[Deleted]]

Hi,

I noticed that if an EA is tested in strategy tester when logged in on a demo account the result will differ if same EA is runned with same settings when logged in into a live account.

If I strategy test my EA logged in to the demo account it generates twice as much profit as it does when strategy tested during a login on a live account.

I guess that the data collected to run the test differs somehow (?), but what differs?
