then i start to investigate how TODAYS big successful DAY traders go about their business. (harris brumfield, paul rotter etc) NONE of these guys seem to advocate such small %. they seem to take the approach that if they are right, they want to be right in a big way. large traders i know personally also have a similar approach. suggest to them only risking 2% and see how hard they larff!!
It would be very interesting to see any hard data and their sources for the above study.

im sure we are all aware of the 'classical' trading texts. they all seem to have this concept of risk management & position sizing theories of only risking 2% of the account.
According to the data in Soros' Alchemy of Finance, it seems to me, as my calculations based on estimated daily volatility might be wrong, roughly he did apply the 2% rule on each market of his investment/ speculation portfolio, probably for diversification purpose.
