Does MT4 Tester account for Swaps/Commissions?

I'm pretty sure the answer is obvious according to test results but just wanted to run it by the gurus here.

Does MT4 back tests account for swaps and commissions taken from the symbol properties window off the server?

I'm assuming it does because I have both no commission and commission based accounts from the same broker.

If I put the SAME SPREAD such as 25 pippettes in both accounts and test the same EA with the same data and symbol, the no commission account generates more profit at 25 pippettes. I can assume it's adding commission to the commission account on top of that.

If I put a lower spread in the commission account closer to the real spread but less than a total of 25 pippettes spread plus commission, the commission account generates higher profit.

So I can assume that the MT4 is taking commissions into account, which is taken off the server from the symbol properties window in MT4.

I don't remember seeing any confirmed documentation from the MT site regarding this.

The question that remains is does MT4 tester also include swaps in calculation of its figures?

I don't think that the swap/commission are used in tester.

But the difference in your results (different brokers) is normal as both platforms use different datas.

It's the same broker. Same data. Same platform. Same server. Just different calculation of commission vs. spread on each account.

But I am still unclear on what I should do with different pairs. My broker is IC Markets, which charge $7/RTL.

So according to the related thread can I simply add 7 pips to my spread in MT4 Tester? Am I understanding this correctly? Is it also dependent upon the pair tested?

MT4 Tester should just have another Tester field for commissions, but since they don't there must be a way to account for the commission.

Definitively not. Adding to the spread won't simulate the commission ... but modifying your entry/exit points ...

Yes, that makes sense. So what is your advice to factor in commissions please?

Maybe work the backtest report in excel ...

I am optiimising. No backtest report.

Please be aware that MT4 tester apply Swaps and Commissions from the your latest connected account and use them while testing/optimizing. But MT4 tester doesn't save Swaps history.

I think this is more or less right, I was very impressed when I made an EA that just opened 1 lot long and do nothing more, when I put that 1 lot on 2013 on NDX until today it gave me looses, you can imagine how we are scammed with this swap thing.
