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
Description:
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.
Calculation:
Sum over n time periods of
call volume * (close - (high + low)/2)
