Quote from tiddlywinks:
None of it matters because 1) gross and/or net is not a factor for win/loss ratio. 2) the point has been made "realistic per trade profitability" is a useless statistic, just like win-loss ratio.
Trade On!
You are the only one talking about win-loss ratios.
Gross and net are definitely important for a trader. If my wins gross $500/trade, but my losses gross $600/trade and my winning percentage is 50%, I am losing net $100/trade. How can that not matter?
Niederhoffer wasn't saying "My winning trades averaged $70 over 2 million contracts" and providing no information on his losing trades, he was saying "Adding together all of my wins and all of my losses, I made $140 million over 2 million contracts traded, for an average of $70 per contract traded". Win-loss ratios don't factor into it at all.
Now, do you understand? The question is about the likely maximum productivity for trading capital. That's why I added that I would like to know Niederhoffer's average trade duration for those trades, to figure out how much he made per minute, which would give me a better estimate of that maximum likely productivity, at least as measured against someone whose track record is publicly-known.
