/*
Stochastic is an oscillator that measures the position of a stock OR security compared with its recent trading range indicating overbought OR oversold conditions.
It displays current Day price at a percentage relative to the security’s trading range (High/Low) over the specified period of time.
In a Slow Stochastic, the highs AND lows are averaged over a slowing period. The default is usually 3 for slow AND 1 (no slowing) for fast.
The line can then be smoothed using an exponential moving average, Weighted, OR simple moving average %D.
Confirming Buy/Sell signals can be read at intersections of the %D with the %K as well.

The Stochastic Oscillator always ranges between 0% AND 100%.
A reading of 0% shows that the security’s Close was the Lowest price that the security has traded during the preceding x-time periods.
A reading of 100% shows that the security’s Close was the Highest price that the security has traded during the preceding x-time periods.
When the closing price is near the top of the recent trading range (above 80%), the security is in an overbought condition AND may Signal for a possible correction.
Oversold condition exists at a point below %20. Prices Close near the top of the range during uptrends AND near the bottom of the range during downtrends.
