// This is combo strategies for get a cumulative signal. 
//
// First strategy
// This System was created from the Book "How I Tripled My Money In The 
// Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
// The strategy buys at market, if close price is higher than the previous close 
// during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50. 
// The strategy sells at market, if close price is lower than the previous close price 
// during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
//
// Second strategy
// Determining market trends has become a science even though a high number or people 
// still believe it’s a gambling game. Mathematicians, technicians, brokers and investors 
// have worked together in developing quite several indicators to help them better understand 
// and forecast market movements.
//
// Developed by Modulus Financial Engineering Inc., the prime number oscillator indicates the 
// nearest prime number, be it at the top or the bottom of the series, and outlines the 
// difference between that prime number and the respective series.
//
// WARNING:
// - For purpose educate only
