Hi,
I just started with Zorro and try to figure out how the profit calculation works. I started TradeTest.c with a FXCM demo account and entered and closed 25 EUR/USD.

In the FXCM trading software I see:
I entered at 1.24079 and closed at 1.24039, therefore -4.0 PIP loss. PIPCost 0.081070 => -4.0 PIPs * 0.08107 * 25 = -8.107. In fact, the loss calculated by FXCM is only -8.06. Any ideas where this difference comes from?

In Zorro's result files:
Enter 25L EUR/USD Stop 0.1241 Trail 0.1241 at 19:40:08
[EUR/USD::L9336] Long 25@1.24079 Risk 2504 t at 19:40:08
Stop: 1.1167 Trail: 1.3649 TakeProfit: 0.0000
...
Close Long EUR/USD
Exit [EUR/USD::L9336]
[EUR/USD::L9336] Sell 25@1.24051: -9.56 at 20:01:11
Entr 1.24079 Exit 1.24051 Spr 0.00012 Slp -0.00 Rol 0.00 Com 1.50 Pool 25
Why does Zorro state that the exit is 1.24051? Has the spread been added? And Zorro added -1.5 for commission, although FXCM does obviously not charge commission (which is probaly only true with the demo account). Is that correct?

The differemce are small, but before spending real money I would like to understand the basics.

Thanks
