The main purpose is to show how we include the Kelly ratio into our scripts for dynamic position sizing based on the performance of the strategy on a per trade basis.
We've also included the usual take-profit and stop-loss parameters in the event you want to play a little :)
We hope this helps you advance your personal system.
