// This is combo strategies for get 
// a cumulative signal. Result signal will return 1 if two strategies 
// is long, -1 if all strategies is short and 0 if signals of strategies is not equal.
//
// 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.
//
// Secon strategy
// The Average Directional Movement Index Rating (ADXR) measures the strength 
// of the Average Directional Movement Index (ADX). It's calculated by taking 
// the average of the current ADX and the ADX from one time period before 
// (time periods can vary, but the most typical period used is 14 days).
// Like the ADX, the ADXR ranges from values of 0 to 100 and reflects strengthening 
// and weakening trends. However, because it represents an average of ADX, values 
// don't fluctuate as dramatically and some analysts believe the indicator helps 
// better display trends in volatile markets.
