Variable List Abbreviation: Accum1OpnInt
Variable Mode(s): Stock and Futures1
[ Note: appears in indicator list only after high, low, and open interest selected ]
Parameter(s): Accum1OpnInt time periods
Description:
Sum of weighted open interests where each time period the 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 periods of
open interest * (close  low)  (high  close)
( high  low )
Notes:  if (highlow = 0) for any time period then zero is used in above summation
