/*The Disparity Index is a simple and efficient oscillator indicator.It represents the percentage that the closing price deviates 
above or below from a chosen average.Its main purpose is capital preservation(reduced and controlled risk plus profits locked in).
In volatile markets, it’s difficult to forecast the formation of peaks and troughs. The disparity index is an indicator 
that helps you squeeze the best out of a trend whether you are trading equities, futures, or forex.*/
//NOTA:(other author)The idea is to Buy stocks that are in intermediate AND long term uptrends but are pulling back on a Short term basis.
