IDEA is to easily spot the length of a calm periods based on OBV.
Some says that after a longer OBV-calm (but not supercalm) period up or down rallies are somewhat more likely)
METHOD: variance of OBV
ADVISE: cannot be used on its own, just with others (RSI, CCI, Coppock, MACD etc.)
Period shall be adjusted to the market.
PERSONAL: I also use it to evaluate...
