Variable List Abbreviation: Accum1PutOpnInt
Variable Mode(s): Futures2
[ Note: appears in indicator list only after high, low and put open interest selected ]
Parameter(s): Accum1PutOpnInt time periods
Description:
Sum of weighted put open interests where each time period the put open interest is weighted by the difference, relative to the total range, between the high & closing price and low & closing price. 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 near the high results in a positive weight, while a close near the low results in a negative weight.
Calculation:
Sum over n time periods of
put open interest * (close  low)  (high  close)
( high  low )
Notes:  if (highlow = 0) for any time period then zero is used in above summation
