// 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
//    This indicator plots average of three different length CMO's. This indicator 
//    was developed by Tushar Chande. A scientist, an inventor, and a respected 
//    trading system developer, Mr. Chande developed the CMO to capture what he 
//    calls "pure momentum". For more definitive information on the CMO and other 
//    indicators we recommend the book The New Technical Trader by Tushar Chande 
//    and Stanley Kroll.
//    The CMO is closely related to, yet unique from, other momentum oriented 
//    indicators such as Relative Strength Index, Stochastic, Rate-of-Change, etc. 
//    It is most closely related to Welles Wilder?s RSI, yet it differs in several ways:
//    - It uses data for both up days and down days in the numerator, thereby directly 
//    measuring momentum;
//    - The calculations are applied on unsmoothed data. Therefore, short-term extreme 
//    movements in price are not hidden. Once calculated, smoothing can be applied to 
//    the CMO, if desired;
//    - The scale is bounded between +100 and -100, thereby allowing you to clearly see 
//    changes in net momentum using the 0 level. The bounded scale also allows you to 
//    conveniently compare values across different securities.
//
// WARNING:
// - For purpose educate only
// - This script to change bars colors.
