in a rough way,
AverageProfit = AverageProrfitPerTrade * ProbailityWinning - AverageLossPerTrade * ProbabilityLosing,
精準, if by it we mean to improve winning percentage, is a self evident argument. (The other story is to increase averge profit and reduce average loss, which is the classic "cut loss fast and let profit run". )
I can appreciate the statement that sometimes you should not pursue 精準 beyond everything else, for example, when you do a large size etc. But to qualitatively say you don't need 精準 without mentioning the context, it's really as helpful as it's meaningless. |
