William's Variable Accum/Dist - Volume


William's Variable Accum/Dist - Volume

Variable List Abbreviation: VarAcc/Dist-Vol


Variable Mode(s): Futures1

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


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



Sum of weighted volumes where each time period the 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.



Sum over n (time periods) time periods of


volume * (close - open)

           ( high - low )


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