This indicator is very interesting for detection of stocks volumes large increase. By testing the high and low price of the previous candle, we affect the oscillator by adding or substracting the current price range multiplied by the present volume. While a new bullish trend is actually forming the oscillator make new highs or new lows for a bear market.

By adding the weigth of the volume to the actual range, high volumes help identifying the premise of a new trend of a reversal one. The signal line made of an exponential moving average also add information on the trend continuation or not.

If price fail to make new upper or lower range than the previous one, then the oscillator will stay flat until price is making a significant move.

This indicator deserve more exploration and would be converted to a stock screener for stocks picking. Anyone ?

if(barindex>10) then
sRange = (high-low)

 if(high<high[1] AND low<low[1]) then
     CumVolVel = CumVolVel[1]-sRange*Volume
   elsif(high>high[1] AND low>low[1]) then
     CumVolVel = CumVolVel[1]+sRange*Volume
   else
     CumVolVel = CumVolVel[1]
 endif
endif

avg = exponentialaverage[p](CumVolVel)

RETURN CumVolVel coloured(255,0,0) as "Cumulated volume", avg coloured(0,0,255) as "signal line"
