// 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 gauges the magnitude of price and volume movement. 
// The indicator returns both positive and negative values where a 
// positive value means the market has moved up from yesterday's value 
// and a negative value means the market has moved down. A large positive 
// or large negative value indicates a large move in price and/or lighter 
// volume. A small positive or small negative value indicates a small move 
// in price and/or heavier volume.
// A positive or negative numeric value. A positive value means the market 
// has moved up from yesterday's value, whereas, a negative value means the 
// market has moved down. 
//
// WARNING:
// - For purpose educate only
// - This script to change bars colors.
