I made 2 trades. 1st trade was closed within the day and I brought the 2nd trade over night. 1st trade was fine but not for the 2nd trade. I'm using GFT dealbook by the way. Please enlighten me. I'm very confuse about bring position overnight.

1st Trade

Total Equity: USD 2,609.49

Entry position: 131.69 ( Short position )

Closed position at 1.3157 ( Profit 9 pips )

I traded EUR/USD and profit $18 ( 2 mini lots )

* My new total equity is : USD 2,609.49 + USD 18 = USD 2,627.49


2nd Trade

Total Equity: USD 2,627.49

Entry position: 1.3164 ( Long position ) - 2 mini lots again

*** The price keeps going down after I entered the long position. Before I switch off my PC and go to bed, I've lost about 11 pips. Tomorrow morning when I wake up, this is what happens.

MY ENTRY POSITION FROM 1.3164 BECOMES 1.3158. WHY? Anyway I closed my position at 1.3163 and lose 1 pip. My total equity should be USD 2,627.49 - USD 2 ( The lost of 1 pip ) = USD 2625.49. But why is it USD 2,621.20?
Where the the difference between USD 2,627.49 and USD 2,621.20 go?

Questions

1) Why did the position from 1.3164 can change to 1.3158 if I bring position overnight?

2) Where did the between USD 2,627.49 and USD 2,621.20 go?
