Designing A Money Management Strategy Using Volatility-Based Stops And The Kelly Criterion
by Ray Overholser,O.D.
Sorting out the criteria for a coherent money management plan is a complex, detailed job. Using a spreadsheet to keep track of the logic helps ensure nothing has been omitted.
With a little planning, you can develop a logically sound money management system. Historically, too much emphasis has been placed on the development of
profitable entry and exit rules, whereas the determination of the proper number of contracts or
shares to trade has been treated as a distant afterthought.
An individualized money management algorithm (using a spreadsheet program such as Microsoft Excel) will control the equity growth of any positive-expectancy system as a direct function of using correct position sizing. Risking too large a portion of trading capital per position will eventually cause even the most profitable trading system to fail.
