I found this strategy description on the web and use my limited knowledge translate to PRT robot, please kindly try, comment and feel free modify to fit for your need.

It is mainly composed of trading criteria based upon a set of 3 moving averages, breakout of recent highest high or lowest low and on a candlesticks pattern.

Settings are optimized (please read the code to find what are the optimized variables). A Walk Forward analysis is attached.

The code also embed:

• a money management position sizing
• a trailing stop based on Max Favorable Excursion (MFE trailing stop)
