// Based on Normalized Smoothed MACD by Dreadblitz
Old one was just an oscillator, I changed a few things
1) It now paints the line green/orange
2) The trigger (green/red) is now based on a signal
3) The signal is basically isUp, but with some additional controls, e.g.
4) (new) There is an embedded stoploss. This is a growth/decay function that decays...
