Reverse
 

Short Name: Reverse

Definition: Returns an array of values representing the opposite of the array passed as parameter

Usage: reverse(array)

Objective:
  • Returns an array of values where the first value becomes the last one and the last value becomes the first one
  • Returns an array of values.

Note:
  • Sometimes, often in the case of cumulative indicators, you’ve to build a “For” loop starting with the oldest values

Examples:
  • reverse(array), if array is 1,2,3, then returns 3,2,1
  • OBV:
  • leVol = reverse(volume)
  • leClose = reverse(close)
  • leClose1 = shiftedRight(leClose,1)
  • test = leClose < leClose1
  • accumulate(obv0,0)
  • for(0,histoRange)
  • if(var(test,0)) then
  • dummyPlus = var(leVol,0) + var(obv0,0)
  • accumulate(obv0,dummyPlus)
  • else
  • dummyMoins = 0 - var(leVol,0) + var(obv0,0)
  • accumulate(obv0,dummyMoins)
  • endif
  • endfor
  • notifyresult(reverse(obv0))
