LarryWillians - Simple Strategy

A simple and classic strategy on market, created by LarryWillians using a EMA9.
The brute model use a Cross from closing price on EMA9. But occurs many false entries.
In other to correct this kind of thing, I add a SMA21 to confirm the trend and decrease numbers of false trades.
The strategy waits to break the last High (for buy) a position.
As a strategy requires a Risk Mannager, I created a simple way to trailing this, as well a Take Proft and Stop Loss in %.
Is not the best strategy but, is one of the most famous on financial markets. I did my adaptive version as simples as it is :)
