I thought when one trading day ends, the maximum drawdown will be recorded permanently in that month. But after review some trade's statistics data, I found that's not true. Could someone help me make this clear? Thanks.

I ditto that! I would like to know when the stats become permanent. Is it at the end of day? I saw the note for the drawdown about "maximum equity's consecutive depreciation". Is that two days in a row or what? Thanks
