   For financial markets, Portfolio Management Formulas by Ralph Vince develops a similar strategy. It too is based on the Kelly Criterion. But it assumes you already have a profitable strategy as opposed to saying "do this system".

   I'm not in any way related to the above authors, nor their books.

   A similar (but more useful) position sizing strategy is the Optimal F formula, described by Ralph Vince in his book Portfolio Management Formulas. But its real value is in showing you your 'cliff of death' curve: how close you can get to bankruptcy given your position sizing.

   In my opinion, position sizing is more way more important (and less understood) than market timing.
