PZO - Price Zone Oscillator - Pro Real Time Formula

// Stocks & CommoditiesV. 29:6 (28-35): Entering The Prize Zone by Walid Khalil and David Steckler
// for daily and weekly charts

rdue = close*(close-close[1])/(ABS(close-close[1]))

//(close-close[1])/(ABS(close-close[1]): all this expression is alwyas = 1: only sign changes for calculating VP
// (close-close[1])/(ABS(close-close[1])
// closing position
CP=ExponentialAverage[n](rdue)
// total close
TC=ExponentialAverage[n](close)
PZO = 100*CP/TC
return PZO coloured(250,50,50) as "PZO" , ADX[n] as "adx"

// deafult, n = 14
//suggestion: insert ADX only if you use another graph in addition to VZO (and not in the same rectangle)
// see blog http://www.fergo.co/2011/08/vzo-volume-zone-oscillator-pro-real.html
// difficult to use: see articles for system rules strategies and for iterations with VZO (Volume Zone Oscillator)
//indicator zones: 60, 40, 15, 0 -5, -40, -60 (same as VZO)
// add horizontal lines (naturally, if you use another graph in addition to VZO)
