Vervoort Volatility Bands [LazyBear]

This is Mr. Vervoort's take on volatility bands. Sticking to his style, he uses highly smoothed data everywhere, also improves on the way the bands are calculated. Is this better than others? I will let you guys decide :)

MidLine = plot (sma(medianAvg, al), color=gray, title="MidLine")
UpperBand = plot (ema(medianAvg, al) + devHigh, color=red, linewidth=2, title="UpperBand")
LowerBand = plot (ema(medianAvg, al) - devLow, color=green, linewidth=2, title="LowerBand")
