Algorithm 3. Oscillation Calculation.

1: function OscillationCalc(indexVals[[], windowStart, winSize)

2:  lowestVal = getLowestVal(indexVals)

3:   movedZero = lowestVal–0.01*lowestVal

4:   oscillation = 0

5:   for i between 1 and windowStart–1 do

6:    absDiff = ABS((indexVals[i]-indexVals[i-1])/(indexVals[i-1] -movedZero))

7:    if absDiff ≥ 5.0 then oscillation += 1000

8:    else if absDiff ≥ 1.0 then oscillation += 100

9:    else if absDiff ≥ 0.5 then oscillation += 10

10:    else if absDiff ≥ 0.25 then oscillation += 1

11:    end if

12:   end for

13:   for i between windowStart+winSize and indexVals.size()-1 do

14:    absDiff = ABS((indexVals[i]-indexVals[i-1])/(indexVals[i-1] -movedZero))

15:    if absDiff ≥ 5.0 then oscillation += 1000

19:    end if
