// 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
// A technical indicator developed by Tushar Chande to numerically identify 
// trends in candlestick charting. It is calculated by taking an 'n' period 
// moving average of the difference between the open and closing prices. A 
// Qstick value greater than zero means that the majority of the last 'n' days 
// have been up, indicating that buying pressure has been increasing. 
// Transaction signals come from when the Qstick indicator crosses through the 
// zero line. Crossing above zero is used as the entry signal because it is indicating 
// that buying pressure is increasing, while sell signals come from the indicator 
// crossing down through zero. In addition, an 'n' period moving average of the Qstick 
// values can be drawn to act as a signal line. Transaction signals are then generated 
// when the Qstick value crosses through the trigger line.
//
// WARNING:
// - For purpose educate only
// - This script to change bars colors.
