Variance of OBV

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 how long an uptrend/downtrend is "normal" and when it is a "changer".
Also to see if a market is too flat. (No changes in flat periods is also not a good sign for me)
Also to evaluate magnitude of bursts.
Have fun, use stops, avoid FOMO and comments welcome!
