Drawdown

Has the algorithm been changed? It is calculating higher positive equity to lower positive equity in a single trade as DD… this is not DD and is addressed in the sharpe ratio. DD is negative dollar amount experienced against the equity value prior to the trade as the benchmark. IOW, if I am in a trade which is up $1000, then falls to +$500, then back up to $1000, that "fall" is not DD, but C2 is calculating it as so… Said another way, the highest point of equity intra-trade is not the benchmark on which the DD is calculated - again, the benchmark is the equity value prior to the position.
