I was checking results from an FSB Pro generated strategy on an FSB build. The order price in the journal matched up, but the average order price did not. I believe I have all of the settings the same. I cannot figure out what I am missing. I have attached images below.

figures in the example:
                    Position      Ord Price       Ave Price       Spread      Floating P/L
FSB Pro        1                1.54303         1.54283        .20            2.73             
FSB              1                1.54303         1.54283        .20            2.73             
FSB Pro        38              1.58022         1.56063        .20            -35.93                                   
FSB              38              1.58022         1.56412        .20            -34.35                                           

This affects every trade including when the position is reduced (ie the P/L at position 237).
The way I believe it works is: if the spread is .20 (or 20 pips in 5 point system), the average price is reduced by .00020 for the opening position. so for position 1 above the order price is 1.54303-.0002 = 1.54283. Which is correct for both applications. Then when i add to the position: ( (1.54303-.0002)+(1.58022-.0002) ) = 3.12285 / 2 for the average price of ---> 1.561425. Which is what is showing up for FSB Pro, but is not what is showing up for FSB. Does anyone know how FSB is calculating it, vs FSB Pro? The difference greatly affects the outcome of the strategy.

Another question from looking at the journal is that the entire spread is applied on the opening position and not the closing position (instead of dividing the spread by 2 on the opening and closing), is that correct?

Lastly I do not understand the swap entry in the journal calculations, can anyone explain it to me, I have looked but cannot find an answer.

thanks for any help.
