The Portfolio stats in EA Studio aggregates the deals. It means that if we have several deals at one bar opening, the portfolio will consider them as one cumulative deal. It will take the net profit/loss from them, but it will count them as one operation. It really changes the numbers of the deals shown and may reflect on stats that counts the deals. However most of the other stats are reliable.
Portfolio ignores the deals that have profit or loss lower than 0.01. This is done to improve the performance. However the deals that close at zero (including the spread and the swaps) really doesn't matter for the portfolio.
It is a portfiolio after all. It may be hedging (like now) or netting (coming soon). The stats is more or less calculating on a netting behaviour.
