There are some brokers that don't report commissions via the regular MT4 field, but rather as deposit/withdrawal records. A popular example here is MB Trading. Since they have variable commissions, depending if the order was market or limit, they report part of the commission in the entry corresponding to the trade, and another part of the commission as a separate entry, of type "balance", where they put some comment like "Comm. for Close #ticketNumber" or "Credit for Close #ticketNumber".

For an EA that has a very low Pips Expectancy (say 1.0 pips), and in an account where commissions are high relative to that, say 0.8 pips, there is a real problem resulting from above mentioned broker reporting: the myfxbook account will show to be (much) more profitable as it really is, since the commission records will be reported as withdrawals (as if you took home the profits, where instead they were not your profits in the first place).

My suggestion here is to compute the commission reported in the Trade Stats as not only the sum of commissions of all trade records, but also add the sum of balance records where the comment matches known patterns.

A similar suggestion goes for reporting Interest: use the balance records that have "Swap" or "Rollover" in the comment field.

This could be tricky to implement, but will certainly make reporting more accurate. I thought about implementing it and it I think you have enough data to have this feature not only correctly compute the Commission and Interest at the account level, but also for each specific pair (commissions entries have the ticket number they correspond to in the comment field, and for Interest the "Swap" and "Rollover" comments also included the pair to which they correspond to).

Thanks for considering my suggestion!
