// 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 is RSI indicator which is more sesitive to price changes. 
// It is based upon a modern math tool - Laguerre transform filter.
// With help of Laguerre filter one becomes able to create superior 
// indicators using very short data lengths as well. The use of shorter 
// data lengths means you can make the indicators more responsive to 
// changes in the price.
//
// WARNING:
// - For purpose educate only
// - This script to change bars colors.
