Brett,

That is very good.  As a slilghtly different method  I take 60% of my chips and divide it by the
number of commodities or equities I want to trade.  Then, if it is for stocks I would divide by the
share price to get the number of shares to trade (I only trade commodities), and round it down to the
nearest round lot.  If it is for a commodity trade I divide by the margin to get the number of
contracts to trade.  I always trade the same size when I have a loser, because I want to win it back
at the same rate at which I lost it.  The original 40% remains liquid (say in Treasury's or a fund)
incase I get killed somewhere, so I still have some chips to play the game. Once a month I take a
total and see what the new 60% figure is and make an adjustment somewhere or add something new if I
want to.  Just a thought.  AMA
