There are some categories in a strategy optimization report, such as
1. Net Profit
1. Gross Profit
1. Gross Loss
1. Total Trades
1. % Profitable
1. Winning Trades
1. Losing Trades
1. Avg Trade
1. Avg Winning Trade
1. Avg Losing Trade
1. Win/Loss Ratio
1. Max Consecutive Winners
1. Max Consecutive Losers
1. Avg Bars in Winner
1. Avg Bars in Loser
1. Max Intraday Drawdown
1. Profit Factor
1. Return on Account

In them, (16) Max Intraday Drawdown has the same value with the Max Strategy Drawdown in a Strategy Performance Report.
In most cases the difference is not serious between Max Strategy Drawdown and Max Close To Close Drawdown in the Strategy Performance Report; however, it shows a large amount of gap when a chart suffers abrupt and drastic change in its value.
So it is enormously helpful for me if a new category 'Max Close To Close Drawdown' is added in Strategy Optimization Report.
