William's Variable Accum/Dist - Call Volume

Variable List Abbreviation: VarAcc/Dist-CallVol

 

Variable Mode(s): Futures2

[ Note: appears in indicator list only after open, high, low, and call volume selected ]

 

Parameter(s): VarAcc/Dist-CallVol time periods

 

Description:

Sum of weighted call volumes where each time period the call volume is weighted by the distance between the opening and closing price relative to the total time period range.  The weighting effectively gives a large weight to time periods in which the open and close are dramatically different ( a possible upward or downward trend ).  A close above the open results in a positive weight, while a close below the open results in a negative weight.

Calculation:

Sum over n (time periods) time periods of

 

call volume * (close - open)

                 ( high - low )

Notes:  - if (high-low = 0) for any time period then zero is used in above summation
