I would like to see MyFXBook to count on broker's commission, as I think that most serious brokers out there are not those with fixed spreads, but with commission.
I would LOVE to have the ability to switch to 'pips including commission' in the detailed report - if I switch it on, everywhere there are pips, there would also be 'pips including commission', as each commission actually widens the spread by certain amount of pips. You can get the amount of pips that the commission took on a certain trade like this:
Trade's commission in USD (P/L in USD for certain trade / trade's P/L in pips)
