TREND LINE through Peaks and Troughs

  parthapersonal

  Hello,

  I have identified the Peaks and Troughs as per the enclosed code.

  Now , if I want to join the 2 higher high troughs and 2 lower low peaks within a timeframe (e.g. from 15:00 to 23:00) how to do it?

  Example is enclosed where manual trend lines are drawn between the said period.

  Any help would be highly appreciated.

  Regards,

  Peak-Trough-Line

  You need to give high TT’s and the low TT’s different names and store the previous value when a new value is recorded. You also need to store the barindex.

  Something like this perhaps. Not tested.

  //VARIABLES H2=high[2] H1=HIGH[1] H0=HIGH[0] L2=LOW[2] L1=LOW[1] L0=LOW[0] //PEAK iF H1>H2 and L1>L2 and H0<H1 AND L0<L1 AND CLOSE<H1 then lasthtt = htt lasthttbar = httbar htt=H1 httbar = barindex[1] if lasthttbar <> lasthttbar[1] then DRAWLINE(lasthttbar,lasthtt,httbar,htt) COLOURED(0,128,0) endif endif //TROUGH iF H1<H2 and L1<L2 and H0>H1 AND L0>L1 AND CLOSE>L1 then lastltt = ltt lastlttbar = lttbar ltt=L1 lttbar = barindex[1] if lastlttbar <> lastlttbar[1] then DRAWLINE(lastlttbar,lastltt,lttbar,ltt) COLOURED(128,0,0) endif endif return

  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 27 28 29 30 31 32 33

  //VARIABLES H2=high[2] H1=HIGH[1] H0=HIGH[0] L2=LOW[2] L1=LOW[1] L0=LOW[0]   //PEAK iF H1>H2 and L1>L2 and H0<H1 AND L0<L1 AND CLOSE<H1 then lasthtt = htt lasthttbar = httbar htt=H1 httbar = barindex[1]   if lasthttbar <> lasthttbar[1] then DRAWLINE(lasthttbar,lasthtt,httbar,htt) COLOURED(0,128,0) endif endif   //TROUGH iF H1<H2 and L1<L2 and H0>H1 AND L0>L1 AND CLOSE>L1 then lastltt = ltt lastlttbar = lttbar ltt=L1 lttbar = barindex[1]   if lastlttbar <> lastlttbar[1] then DRAWLINE(lastlttbar,lastltt,lttbar,ltt) COLOURED(128,0,0) endif endif   return

  Hello Vonasi,

  Is it possible not to extend the line to its left? if yes then how please? and if I want the line to be drawn for today’s peaks and troughs only then should I check “if date=today”?

  That’s possible but only with PRT v11 and the DRAWRAY instruction.

  v11 only

  defparam calculateonlastbars=300 //VARIABLES H2=high[2] H1=HIGH[1] H0=HIGH[0] L2=LOW[2] L1=LOW[1] L0=LOW[0] //PEAK iF H1>H2 and L1>L2 and H0<H1 AND L0<L1 AND CLOSE<H1 then lasthtt = htt lasthttbar = httbar htt=H1 httbar = barindex[1] if lasthttbar <> lasthttbar[1] then DRAWRAY(lasthttbar,lasthtt,httbar,htt) COLOURED(0,128,0) endif endif //TROUGH iF H1<H2 and L1<L2 and H0>H1 AND L0>L1 AND CLOSE>L1 then lastltt = ltt lastlttbar = lttbar ltt=L1 lttbar = barindex[1] if lastlttbar <> lastlttbar[1] then DRAWRAY(lastlttbar,lastltt,lttbar,ltt) COLOURED(128,0,0) endif endif return

  Try this for just drawing the latest lines:

  As Nicolas says you need DRAWRAY and v11 to get rid of the bit of line to the left.

  defparam drawonlastbaronly = true //VARIABLES H2=high[2] H1=HIGH[1] H0=HIGH[0] L2=LOW[2] L1=LOW[1] L0=LOW[0] //PEAK iF H1>H2 and L1>L2 and H0<H1 AND L0<L1 AND CLOSE<H1 then lasthtt = htt lasthttbar = httbar htt=H1 httbar = barindex[1] endif DRAWLINE(lasthttbar,lasthtt,httbar,htt) COLOURED(0,128,0) //TROUGH iF H1<H2 and L1<L2 and H0>H1 AND L0>L1 AND CLOSE>L1 then lastltt = ltt lastlttbar = lttbar ltt=L1 lttbar = barindex[1] endif DRAWLINE(lastlttbar,lastltt,lttbar,ltt) COLOURED(128,0,0) return

  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 27 28 29 30 31

  defparam drawonlastbaronly = true   //VARIABLES H2=high[2] H1=HIGH[1] H0=HIGH[0] L2=LOW[2] L1=LOW[1] L0=LOW[0]   //PEAK iF H1>H2 and L1>L2 and H0<H1 AND L0<L1 AND CLOSE<H1 then lasthtt = htt lasthttbar = httbar htt=H1 httbar = barindex[1] endif   DRAWLINE(lasthttbar,lasthtt,httbar,htt) COLOURED(0,128,0)   //TROUGH iF H1<H2 and L1<L2 and H0>H1 AND L0>L1 AND CLOSE>L1 then lastltt = ltt lastlttbar = lttbar ltt=L1 lttbar = barindex[1] endif   DRAWLINE(lastlttbar,lastltt,lttbar,ltt) COLOURED(128,0,0)   return

  Many thanks Vonasi and Nicolas. Much appreciated.

  I have modified the code, but could not set alarm as it is not identifying the lines’ value correctly,

  Is it possible to fix it?

  Trend line

  You cannot set an alarm to detect lines drawn in a custom indicator. You will need to calculate the projected forward line value for each bar moving forward by subtracting the lower point value from the higher point value and dividing by the number of bars between them, then add this on to the most recent value for each bar moving forward.

  Once you know this value you can test to see if close is above or below it etc.

  One downside of this calculation is if you use a time frame with missing bars as these can cause steps in the forward calculation.

  An example of this sort of calculation can be found here:

  https://www.prorealcode.com/prorealtime-indicators/last-two-pivots-support-and-resistance-lines/

  In fact it might be easier for you just to adapt that indicator to do what you want.

  Dear Vonasi, in your last example (https://www.prorealcode.com/prorealtime-indicators/last-two-highest-high-and-lowest-low-lines-yearly-quarterly-monthly-weekly-daily-4-hour-and-1-hour/) you have drawn lines without extending to the left and without “DRAWRAY”. So if that is possible in your example, why can’t we do the same to my indicator (with your help) please?

  The lines are segments, not extending on the left or the right.

  Replace DRAWLINE with DRAWSEGMENT.

  You are right Nicolas. When can we have “Style” with DRAWLINE and DRAWSEGMENT to increase line thickness? Is Style available with DRAWRAY?

  Graphical objects can be styled, but only with PRT v11.
