FYI, I've done a little more investigating on this and pretty much determined that FSB is correct in its calculations and labeling. I also verified this with my broker because I wanted to make sure I was doing this correctly (and math is not my strong suit).
Basically, the way I confirmed it was correct is:
Strategy Properties-> Trade constant # of lots -> 1.0
Market-> Charges-> Spread 2.0
Then in my journal, I noted the correct USD value from trades in the spread column.
IMPORTANT: if you are on a mini account with lot size 10,000, you must change this under Market-> Edit Instruments because the default setting may be a full lot of 100,000.
For mini accounts (10,000 lot size) a movement of 1 pip translates to USD $0.10. So if your spread setting is 2.0, then that should show in the journal as $0.20
(NOTE: it would be helpful if the FSB developers could change the default spread for the built-in instruments to be more typical. For example EURUSD default spread is 20.0 which doesn't seem right. A typical spread should be about 2.0 I think.)
