A trade profit has not much to do with the prevailing exchange rate. Brokers use their published pip costs for converting price differences to profits. They do not use the dollar exchange rate for obvious reasons. The exchange rate is different any day and traders would not appreciate when it affected all their trade results.

The profit of your trade is about 10.44 pips. The difference to 11.5 is the slippage, which is not rounded because it's a statistical value. When you multiply 10.44 pips with 0.0800 EUR pip cost, you'll get 0.8352 EUR. That's your 84 cents - the exact profit of your trade when you had entered it today with a real FXCM EUR account. I think that's the result you're normally interested in when testing a system.

Entry and exit prices in the CSV contain the spread, but they do not contain the other trade costs - rollover, commission, and simulated slippage. The costs affect the profit, but not the entry and exit price, although for slippage this could maybe make sense. But slippage is simulated separately at the moment.

I hope this helps understanding trade profit. For your experiments you can set Slippage to 0 - then you should really get 11.5 pips profit.
