Use Lower/Higher Low/ High as Trend signal

  Luciole

  Hello,

  I wish to have a Trend indicator based on “higher high (HH) / higher low (HL)    and lower low (LL) / lower high (LH)” system.

  The rules would be the following :

  • Trend UP (+1) :  HH and HL alternating
  • Trend Down (-1) : LH and LL alternating
  • Neutral State (0) : when both are mixing up.

  I guess that “Fractal ZigZag” would be a great help as I’m also considering to implement this in a ProBuilder strat besides my manual trading.

  As per Nicolas comment this zigzag suits well for automatic purposes .

  https://www.prorealcode.com/prorealtime-indicators/fractals-zigzag/

  Yet I can’t figure out how to make that rule check

  I would greatly appreciate your help on this matter as it overpasses my PRT knowledges .  Thanks for any hint ot help on this.

   

  Illustration picture attached. The goal is only to have a barchart indicator (1/0/-1), boxes are just a visual help not mandatory.

  Hello,

  • Sorry for not posting any code snipet but at this point I’m really struggling and all are failing to achieve what I want…
  • Please find the below  picture on Dax Cash Daily View so it can be easier to understand.

  Don’t pay attention to color trendlines at the very top.

  You can notice the code drawing HHHL / LHLL behind

  (Wich isnt suited for ProOrder as per my understanding but it helps to make things clearer on chart)

   

  Kind regards

  The code for this latter indicator is zigzag based and therefore not available to execute an automatic trading strategy under ProOrder. What you are looking for is neither more nor less than a fractal breakout (high / low points), with the condition of bullish or bearish waves, as you describe in your first post.

  • No worries, as said the zigzag code was here only for visual purpose. My attempts are based on Fractal “zigzag

   

  My snippet for TrendUp at line 44. Doesnt seem to be close form what I want from the screenshot above.

  Would you mind hinting more on this ?

  Snippet for trend up try

  In the below version of the code, I add an arrow when a new trend is detected (the new fractal top is higher than the last one). It only marks with an arrow the start of the new trend.

  defparam calculateonlastbars=10000 cp = 3 once lastpoint = 0 if high[cp] >= highest[2*cp+1](high) then PEAK = 1 else PEAK = 0 endif if low[cp] <= lowest[2*cp+1](low) then TROUGH = -1 else TROUGH = 0 endif if PEAK = 1 then TOPy = high[cp] TOPx = barindex[cp] endif if TROUGH = -1 then BOTy = low[cp] BOTx = barindex[cp] endif if PEAK>0 and (lastpoint=-1 or lastpoint=0) then DRAWSEGMENT(lastX,lastY,TOPx,TOPy) COLOURED(200,0,0,255) DRAWTEXT("■",TOPx,TOPy,Dialog,Bold,20) coloured(200,0,0,255) lastpoint = 1 lastX = TOPx lastY = TOPy endif if TROUGH<0 and (lastpoint=1 or lastpoint=0) then DRAWSEGMENT(lastX,lastY,BOTx,BOTy) COLOURED(0,200,0,255) DRAWTEXT("■",BOTx,BOTy,Dialog,Bold,20) coloured(0,200,0,255) lastpoint = -1 lastX = BOTx lastY = BOTy endif //TREND ATTEMPT atr=AverageTrueRange[14](close) if TOPy > TOPy[1] and topy<>lasttop then drawarrowup(barindex,low-atr/2) coloured(0,200,0) lasttop=topy trendup = 1 else trendup = 0 endif RETURN TOPy as "TOPy", BOTY as "BOTy", trendup as "trendup"

  Thanks Nicolas

  see attached “late_signal” compared to my “lightening pattern”.

  I tried to include the condition when Daily candle close higher than previous TOPy (wich make the Close the new potential higher high) :

   

  With Close condition

  cp = 10 //TREND UP ATTEMPT atr=AverageTrueRange[14](close) if (TOPy > TOPy[1] and topy<>lasttop) OR (Close > TOPy[1] )then drawarrowup(barindex,low-atr/2) coloured(0,200,0) lasttop=topy trendup = 1 else trendup = 0 endif

  1 2 3 4 5 6 7 8 9 10 11

  cp = 10   //TREND UP ATTEMPT atr=AverageTrueRange[14](close) if (TOPy > TOPy[1] and topy<>lasttop) OR (Close > TOPy[1] )then drawarrowup(barindex,low-atr/2) coloured(0,200,0) lasttop=topy trendup = 1 else trendup = 0 endif

  Results on the second screenshot. Which looks closer to my expectation. Yet there is some unknown “glory holes” cutting the trend besides the fact that there is HH and HL from the Fractal PoV.

  thanks

  Your version is good, the holes are there because a new topy is detected and your close is not above the previous one anymore.

  BTW you are not testing higher lows in your condition.

  Sorry but I’m seriously confused in these fractals code to achieve what seems to be simple…

  My TrendUP conditions should be the following :

  • (Close > Latest Peak) AND ( Latest Trough > Previous Trough)
  • OR
  • (Close > Latest Trough) AND ( Latest Trough > Previous Trough)

   

  Can you correct me if I’m wrong in the translation into code :

   

  • (Close > TOPy ) AND ( BOTx > BOTx[1])
  • OR
  • (Close > BOTx ) AND (BOTx > BOTx[1])

   

  Thanks

  x = barindex and y = price , so ( Latest Trough > Previous Trough) , should be coded like this:

  ( BOTy > BOTy[1])

  But, keep in mind that this condition will only work once, on the first bar when the new fractal low will be detected and not afterward..

  What seems to be a “neither more nor less than a fractal breakout” is still far away from running properly 🙂

  //TREND UP ATTEMPT atr=AverageTrueRange[14](close) //if ( TOPy > TOPy[1] and topy<>lasttop) OR (Close > TOPy[1]) OR (Close > lastY)then if (Close > TOPx AND BOTy > BOTy[1]) drawarrowup(barindex,low-atr*2) coloured(0,200,0) //lasttop=topy trendup = 1 else trendup = 0 endif

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

  //TREND UP ATTEMPT atr=AverageTrueRange[14](close) //if ( TOPy > TOPy[1] and topy<>lasttop) OR (Close > TOPy[1]) OR (Close > lastY)then   if (Close > TOPx  AND  BOTy > BOTy[1]) drawarrowup(barindex,low-atr*2) coloured(0,200,0)   //lasttop=topy   trendup = 1 else trendup = 0 endif

  Test of  first condition alone :  if (Close > TOPy AND BOTy > BOTy[1])

  Screenshot attached.

  -> The arrow ( under Close of May 27) is  2 candles late.

  25 of May 2020 ‘s CLose was 11387    wich is higher than 11342 So the arrow should had start at this date.

   

  And the result is exactly the same for the second condition (arrown drawn starting of 27 May 2020)

  Second conditions (alone)

  //TREND UP ATTEMPT atr=AverageTrueRange[14](close) //if ( TOPy > TOPy[1] and topy<>lasttop) OR (Close > TOPy[1]) OR (Close > lastY)then if(Close > BOTx AND BOTy > BOTy[1]) then drawarrowup(barindex,low-atr*2) coloured(0,200,0) //lasttop=topy trendup = 1 else trendup = 0 endif

  1 2 3 4 5 6 7 8 9 10 11

  //TREND UP ATTEMPT atr=AverageTrueRange[14](close) //if ( TOPy > TOPy[1] and topy<>lasttop) OR (Close > TOPy[1]) OR (Close > lastY)then   if(Close > BOTx AND BOTy > BOTy[1]) then drawarrowup(barindex,low-atr*2) coloured(0,200,0) //lasttop=topy trendup = 1 else trendup = 0 endif

   

   

  “But, keep in mind that this condition will only work once, on the first bar when the new fractal low will be detected and not afterward..”

  As stated in the first message, this is supposed to be a Trend 1/0/-1 indicator so the signal must be alive as long at the conditions are valids. Are we okay to deal like this as per the code above ? Otherwise it’s an issue.

   

  Thanks for your help, wish we can sort this out so it can assist my manual trading and work on the automatic later. I will share my tought on that.

  So here is new attempt. I mark the bullish trend (trendup variable) with a dark green background on the price chart. I don’t know how the trend is ending, so I reset it on the first trough lower than the previous one.

  defparam calculateonlastbars=3000 cp = 3 once lastpoint = 0 if high[cp] >= highest[2*cp+1](high) then PEAK = 1 else PEAK = 0 endif if low[cp] <= lowest[2*cp+1](low) then TROUGH = 1 else TROUGH = 0 endif if PEAK then //prevtop = topy TOPy = high[cp] TOPx = barindex[cp] endif if TROUGH then prevbot = boty BOTy = low[cp] BOTx = barindex[cp] endif if PEAK and (lastpoint=-1 or lastpoint=0) then DRAWSEGMENT(lastX,lastY,TOPx,TOPy) COLOURED(200,0,0,255) DRAWTEXT("■",TOPx,TOPy,Dialog,Bold,20) coloured(200,0,0,255) lastpoint = 1 lastX = TOPx lastY = TOPy endif if TROUGH and (lastpoint=1 or lastpoint=0) then DRAWSEGMENT(lastX,lastY,BOTx,BOTy) COLOURED(0,200,0,255) DRAWTEXT("■",BOTx,BOTy,Dialog,Bold,20) coloured(0,200,0,255) lastpoint = -1 lastX = BOTx lastY = BOTy endif //TREND ATTEMPT //bullish trend is starting if boty>prevbot and close>topy and lasty<>lasty[1] and not trendup then trendup = 1 endif //bullish trend is ending if trough and boty<prevbot and lasty<>lasty[1] and trendup then trendup=0 endif //trend is up, coloring the background! if trendup then backgroundcolor(0,200,0,50) endif RETURN //TOPy as "TOPy", BOTY as "BOTy", trendup as "trendup"

  Seems perfect Nicolas 🙂

  Thanks a lot

   

  Below, fixed snipet for my personnal ending trend condition.

  + bearish trend

  For trading purpose : In case of a trend up for example, please note that if the trend break on the indicator BUT the price come back 2/3 days after above the break line (wich is the previous higher low), it can be considered as a continuation in the trend up. This is pure discretionary, depending on the asset traded.

   

  // 1 bullish trend is starting if boty>prevbot and close>topy and lasty<>lasty[1] and not trendup then trendup = 1 endif // 1.1 bullish trend is ending if Close < boty then trendup=0 endif // 2 bearish trend is starting if topy<prevtop and close<boty and lasty<>lasty[1] and not trenddown then trenddown = 1 endif // 2.1 bearish trend is ending if Close > topy then trenddown=0 endif

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

  // 1 bullish trend is starting if boty>prevbot and close>topy and lasty<>lasty[1] and not trendup then trendup = 1 endif // 1.1 bullish trend is ending if Close < boty then trendup=0 endif   // 2 bearish trend is starting if topy<prevtop and close<boty and lasty<>lasty[1] and not trenddown then trenddown = 1 endif // 2.1 bearish trend is ending if Close > topy then trenddown=0 endif
