how to count zigzag moves

  Hi

  I would like to count the quantity of zigzag moves of an index/security of a chart

  ex: zigzag moves of 5% of the SPX index

  I have tried a few things but what I get is kind strange,  is it possible? The last attempt was this one but it gives an error message (the following variable is undefined: count )

  thank you

  a= ZigZagPoint[10](close)
  b=count[a]
  c=cumsum (b)
  return c

  Firstly, COUNT is not defined anywhere thus can’t be used.

  Secondly, ZIGZAG returns a value each bar, it doesn’t count swing points, so counting it will return a huge number.

  Thirdly, you can count swing points with this code, but it’s useless as it’s a repainting, so it may change any swing point several bars after they have already been counted as you will easily spot on a 1-second TF (see my attached pic):

  ONCE Count = 0 myZZ = ZigZagPoint[10](close) SwingHI = (myZZ < myZZ[1]) AND (myZZ[1] > myZZ[2]) SwingLO = (myZZ > myZZ[1]) AND (myZZ[1] < myZZ[2]) IF SwingHI OR SwingLO THEN c = c + 1 ENDIF return c AS "Count"

  1 2 3 4 5 6 7 8

  ONCE Count = 0 myZZ    = ZigZagPoint[10](close) SwingHI = (myZZ < myZZ[1]) AND (myZZ[1] > myZZ[2]) SwingLO = (myZZ > myZZ[1]) AND (myZZ[1] < myZZ[2]) IF SwingHI OR SwingLO THEN    c = c + 1 ENDIF return c AS "Count"

  (Sorry same time as Roberto)

  Hi,

  You can try this one…

  I think the calculation of the ZigZag is incorrect, for example if I set a 5% change (from bottom to top or vice versa) then the number of change (points) is incorrect…??

  ZigZag Count

  PercentChange=5 ZZ=ZigZag[PercentChange](Close) If ZZ[1]<ZZ[2] and ZZ>ZZ[1] then BottomCount=BottomCount+1 ElsIf ZZ[1]>ZZ[2] and ZZ<ZZ[1] then TopCount=TopCount+1 EndIf TotalCount=BottomCount+TopCount Return BottomCount as "BottomCount", TopCount as "TopCount", TotalCount as "TotalCount"

  1 2 3 4 5 6 7 8 9 10 11 12 13

  PercentChange=5   ZZ=ZigZag[PercentChange](Close)   If ZZ[1]<ZZ[2] and ZZ>ZZ[1] then BottomCount=BottomCount+1 ElsIf ZZ[1]>ZZ[2] and ZZ<ZZ[1] then TopCount=TopCount+1 EndIf   TotalCount=BottomCount+TopCount   Return BottomCount as "BottomCount", TopCount as "TopCount", TotalCount as "TotalCount"

  Thank you  it works,  just return totalcount

   

   

  PercentChange=5 ZZ=ZigZag[PercentChange](Close) If ZZ[1]<ZZ[2] and ZZ>ZZ[1] then BottomCount=BottomCount+1 ElsIf ZZ[1]>ZZ[2] and ZZ<ZZ[1] then TopCount=TopCount+1 EndIf TotalCount=BottomCount+TopCount Return BottomCount as "BottomCount", TopCount as "TopCount", TotalCount as "TotalCount"

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

  PercentChange=5     ZZ=ZigZag[PercentChange](Close)     If ZZ[1]<ZZ[2] and ZZ>ZZ[1] then BottomCount=BottomCount+1 ElsIf ZZ[1]>ZZ[2] and ZZ<ZZ[1] then TopCount=TopCount+1 EndIf     TotalCount=BottomCount+TopCount     Return BottomCount as "BottomCount", TopCount as "TopCount", TotalCount as "TotalCount"
