William's Variable Accum/Dist - Put Open Interest

Variable List Abbreviation: VarAcc/Dist-PutOpnInt

 

Variable Mode(s): Futures2

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

 

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

 

Description:

Sum of weighted put open interests where each time period the put open interest 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

 

put open interest * (close - open)

                         ( high - low )

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