RWT - Equity Curve calculations - Chronological
Order???Fred,Perhaps it is the accepted
practice to measure drawdowns from the highof a trade and if that is so
then so be it.FWIW... I measure drawdown in terms of my available
equity. (I don'tcount the high price of a current stock trade as
'available equity'.It is only equity in my mind when I close out the
trade. I can affordthis latitude in measuring drawdowns because I use
rigid trailing stops.I can see where someone who had an account value
at the beginning of2000 of a million and who having never sold has an
account value of100,000 might consider it a drawdown. Fortunately, I
cultivated thepractice of cutting losses years ago.Not argueing...
just telling you what is important to me.Phsst--- In
