// This is combo strategies for get a cumulative signal. 
//
// First strategy
// This indicator plots 2/20 exponential moving average. For the Mov 
// Avg X 2/20 Indicator, the EMA bar will be painted when the Alert criteria is met.
//
// Second strategy
//    This indicator plots the oscillator as a histogram where blue denotes 
//    periods suited for buying and red . for selling. If the current value 
//    of AO (Awesome Oscillator) is above previous, the period is considered 
//    suited for buying and the period is marked blue. If the AO value is not 
//    above previous, the period is considered suited for selling and the 
//    indicator marks it as red.
