Variable List Abbreviation: Accum2-CallVol
Variable Mode(s): Futures2
[ Note: appears in indicator list only after high, low and call volume selected ]
Parameter(s): Accum2-CallVol time periods
Sum of weighted call volumes where each time period the call volume is weighted by the distance between the closing price and the range midpoint. The weighting effectively gives a large weight to time periods in which the close is very close to either the high or low ( a possible upward or downward trend). A close above the midpoint results in a positive weight, while a close below the midpoint results in a negative weight.
Sum over n time periods of
call volume * (close - (high + low)/2)
