Swing High / Swing Low

  Hi everyone,

  I am looking for a swinghigh/swinglow function same as the one described here:

  The SwingHigh function returns the high pivot price where a Swing High occurred.

  Syntax

  SwingHigh(Instance, Price, Strength, Length)

  Remarks

  A Swing High occurs when the Price of a bar is at least as high as the same Price on the preceding bar(s), and higher than the same Price on the bar(s) that follow it.

  The input Strength is the number of bars on each side of the SwingHigh. A strength of one indicates that the value returned by the input Price must be greater than or equal to the same value returned for the bar on its left and greater than the bar on its right.

  The input Length refers to the number of bars being examined for the SwingHigh.

  The input Instance refers to which SwingHigh you want to use. For example, if in a twenty-one bar period three swing highs were found, it becomes necessary to specify which SwingHigh is desired. If the most recent SwingHigh is desired, a one (1) would be substituted for the input Instance.

     If no SwingHigh is found in the period (Length) specified, the function will return a minus one (-1). The value of the input Length must exceed Strength by at least one. In addition, the Maximum number of bars referenced by a study (known as MaxBarsBack) must be greater than the sum of the values of Strength and Length.

  Example

  Assigns to Value1 the most recently occurring High in over the last 10 bars that has a strength of 4 on both the left and right sides of the swing bar..

  Value1 = SwingHigh(1,Close,4,10);

  You may search the keyword  ‘swinghigh’ in the link http://help.tradestation.com/09_01/tsdevhelp/subsystems/elword/elword_Left.htm#CSHID=function%2Fslowk_function_.htm|StartTopic=function%2Fslowk_function_.htm|SkinName=ts_slate_skin

  I have started some draft yet found it hard to complete with my limited knowledge, would anyone please complete it? Cheers

  Swinghigh

  For b=0 to length do //Strength For a =0 to strength do countR= Summation [strength](Price[a]<=price[a+1]) countL=summation [strength](Price[a]>=price[a+1])[strength] next If countR =strength and countL=strength then xxxxxxx endif next

  1 2 3 4 5 6 7 8 9 10

  For b=0 to length do //Strength For a =0 to strength do countR= Summation [strength](Price[a]<=price[a+1]) countL=summation [strength](Price[a]>=price[a+1])[strength] next If countR =strength and countL=strength then xxxxxxx endif next

  This the code I wrote for swing HI patterns, if I could understand what you meant.

  If it’s correct, then I (or you if you can code it) can add the opposite swing LO, if desired:

  Swing HI pattern

  DEFPARAM CalculateOnLastBars = 1000 //Length = 100 //Strength = 2 //Input = 1 LeftHI = high[Strength] >= highest[Strength + 1](high[Strength]) //check LEFT side RightHI = high[Strength] > highest[Strength](high) //check RIGHT side SwingHI = summation[Length](LeftHI AND RightHI) //tally swing patterns in the last LENGTH bars // scan all LENGTH bars to retrieve INPUT swing pattern, if any IF SwingHI > 0 THEN InputNum = min(SwingHI,max(0,Input)) Count = 0 j = i FOR i = 0 TO Length - 1 IF LeftHI[i] AND RightHI[i] THEN Count = Count + 1 IF Count = InputNum THEN BREAK ELSE j = -1 ENDIF ENDIF NEXT ELSE j = -1 ENDIF RETURN j

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

  DEFPARAM CalculateOnLastBars = 1000 //Length   = 100 //Strength = 2 //Input    = 1 LeftHI   = high[Strength] >= highest[Strength + 1](high[Strength]) //check LEFT  side RightHI  = high[Strength] > highest[Strength](high)                //check RIGHT side SwingHI  = summation[Length](LeftHI AND RightHI)                   //tally swing patterns in the last LENGTH bars // scan all LENGTH bars to retrieve INPUT swing pattern, if any IF SwingHI > 0 THEN    InputNum = min(SwingHI,max(0,Input))    Count = 0    j     = i    FOR i = 0 TO Length - 1       IF LeftHI[i] AND RightHI[i] THEN          Count = Count + 1          IF Count = InputNum THEN             BREAK          ELSE             j = -1          ENDIF       ENDIF    NEXT ELSE    j = -1 ENDIF RETURN j

  It’s a function (indicator), and you’ll be able to CALL it from your strategy.
