// 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
// The name ‘Floor-Trader Pivot,’ came from the fact that Pivot points can 
// be calculated quickly, on the fly using price data from the previous day 
// as an input. Although time-frames of less than a day can be used, Pivots are 
// commonly plotted on the Daily Chart; using price data from the previous day’s 
// trading activity. 
//
