MVP, C2 computes both figures, and neither are very reliably accurate, and that has been the source of our major frustration with them. On the current TMG page visible to subscribers, the drawdowns are fine for the first few trades, but the last three all show "n/a" because they have bad data that makes the drawdowns per trade appear worse than they were. Then, presumably, the system drawdown is the worst of the individual trade drawdowns. They say they recompute those after the trade has closed, but as you see, that hasn't happened for the last three trades yet.
