Variable List Abbreviation: Accum1Pt+ClOpnInt
Variable Mode(s): Futures2
[ Note: appears in indicator list only after high, low, put open interest, and call open interest selected ]
Parameter(s): Accum1Pt+ClOpnInt time periods
Description:
Sum of weighted put & call open interests where each time period the put & call 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 & call open interest sum) * (close  low)  (high  close)
( high  low )
Notes:  if (highlow = 0) for any time period then zero is used in above summation
