i am confused about commissions and the results in back test.
I have tickstory 1.72 with MT4 build 910 and till now for exporting data to MT4 left "commission" still empty.
I have Roboforex ECN where i have for EURUSD about 0.6 spread and round turn for commissions 4$.
Till now i only have set in tester for spread = 15 to add spread and commissions together as save settings.
So for example i got in back test with a scalper for 2 years a profit result of 290.000 $
Now i have put the commissions by exporting to MT4 into the data and set in tester spread = 9 (for security) and get a profit result of 2 million....!

Again:
1. no commission , but spread 15 = profit 290.000
2. 4$ commission and spread = 9 : profit 2.000.000
But what is wrong ?
What should i do?
And how can i check, if there are commissions calculated in the trade. In BT result i don't see any "commisisons".
Thanks !
