// Wilder was a very influential man when it comes to TA. However, I'm one to always try to think outside the box. 
// While Wilder recommended that the RSI be used only with a 14 bar lookback period, I on the other hand think there is a lot to learn from RSI if one simply slows down the lookback period 
// Same applies for MACD.
// Every market has its dynmaics. So don't narrow your mind by thinking my source code input levels are the only levels that work.
// Since the long lookback period weakens the plot volatility, again, one must think outside the box when trying to guage overbought and oversold levels. 

// Good luck and don't bash me if some off-the-wall FA spurned divergence causes you to lose money.
// And NO this doesn't repaint and I won't answer those who ask.
