There aren't any open trades to display currently. The balance equals the equity, hence there is no open trades. Open orders are closed (but these could be pending orders - and would not be fair to show these as anyone could then copy the pending trades, without buying the EA). I am also interested to see backtests though.
if he was hiding open trades I would agree with you, but he isn't there are just no open trades currently. I know other unscrupulous vendors hide open trades with large drawdowns etc. But I don't think that's happening here.
