Bar Index – Proscreener

  Can anyone help me on this matter ? I have a problem of finding a way to rerun a bar index of highest or lowest criteria. For example I want to find out what is bar index of this statement?

  highest [250](rsi[14](close)).

  Is it possible to get the bar index of such statement. Just to make it clear, I want to know what is bar index that maximum or minimum RSI  happened in the last 250 bars?
  Thanks in advance for your help.
  Hamid

  This could be possible by making a loop through the last 250 periods to find the lowest low and highest high of the RSI:

  RSI highest high BARINDEX

  mrsi = rsi[14] hrsi = 0 for i = 0 to 250 do if mrsi[i]>hrsi then hrsi=mrsi[i] hbar=barindex[i] endif next return hbar

  1 2 3 4 5 6 7 8 9 10 11

  mrsi = rsi[14] hrsi = 0   for i = 0 to 250 do if mrsi[i]>hrsi then   hrsi=mrsi[i]   hbar=barindex[i] endif next   return hbar

  RSI lowest low BARINDEX

  mrsi = rsi[14] lrsi = 10000 for i = 0 to 250 do if mrsi[i]<lrsi then lrsi=mrsi[i] lbar=barindex[i] endif next return lbar

  1 2 3 4 5 6 7 8 9 10 11

  mrsi = rsi[14] lrsi = 10000   for i = 0 to 250 do if mrsi[i]<lrsi then   lrsi=mrsi[i]   lbar=barindex[i] endif next   return lbar

  Not tested, please give us feedback if these codes are working correctly.

  Thank you for your reply. But I have tested this method before, But I don’t know why proscreener doesn’t accept any loop more than 100, it will give an error as infinite loop exit in the code. I want to write a code to find trend of rsi in rising or falling channel. For example something like the image attached. Below is the code I have done so far, sometime it will work fine sometime not. did you come with this idea before or do you have this kind of code?

   

  MinimumRsi=100 meet=0 For x=1 to 100 Do //loop through 100 bar to find Min Rsi IF rsi[14](close)[x] < MinimumRsi THEN MinimumRsi=rsi[14](close)[x] barNb=x ENDIF NEXT isBearish=0 For x=1 to 20 Do // if first 20 bar RSI is less than 40 is bearish mode IF rsi[14](close)[x] < 40 THEN isBearish=1 break ENDIF NEXT fail=1 m=(rsi[14](close)[0]-MinimumRsi)/(0-barNb) //find equation of a line with two points y=mx+b m is slope and b is is the y-intercept. b=MinimumRsi-(barNb*m) FOR i=1 to barNb DO y=m*i+b IF y+0.1 > rsi[14](close)[i] AND y-0.1 < rsi[14](close)[i] THEN meet=meet+1 ENDIF IF y -0.1 > rsi[14][i] THEN fail=0 break ENDIF NEXT condition=0 IF meet >=1 THEN condition=1 ENDIF // if current stock rsi is close to the line SCREENER [condition AND fail AND isBullish]

  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 34 35 36 37 38 39 40 41 42 43 44 45

  MinimumRsi=100 meet=0 For x=1 to 100 Do //loop through 100 bar to find Min Rsi IF rsi[14](close)[x] < MinimumRsi THEN MinimumRsi=rsi[14](close)[x] barNb=x ENDIF       NEXT   isBearish=0 For x=1 to 20 Do // if first 20 bar RSI is less than 40 is bearish mode IF rsi[14](close)[x] < 40 THEN isBearish=1 break ENDIF   NEXT fail=1 m=(rsi[14](close)[0]-MinimumRsi)/(0-barNb) //find equation of a line with two points y=mx+b m is slope and b is is the y-intercept.   b=MinimumRsi-(barNb*m)   FOR i=1 to barNb DO y=m*i+b IF y+0.1 > rsi[14](close)[i] AND y-0.1 < rsi[14](close)[i] THEN meet=meet+1   ENDIF   IF y -0.1 > rsi[14][i] THEN fail=0 break ENDIF NEXT condition=0 IF meet >=1 THEN condition=1 ENDIF   // if current stock rsi is close to the line   SCREENER [condition AND fail AND isBullish]

  Test if barNb is superior to 0 prior of using it as the target of new loop at line 26 (not tested, first thing that come in mind now).

  Hello Hamid and Nicolas, i came to this post casually only now.

  To find the barindex of the highest[250] of RSI you can use this code:

  barindex finder highest

  //RSI highest high BARINDEX myrsi = rsi[14] c1=myrsi>highest[250](myrsi)[1] if a then myindex=barindex endif barHH=barindex[0]-myindex return barHH

  1 2 3 4 5 6 7 8

  //RSI highest high BARINDEX myrsi = rsi[14] c1=myrsi>highest[250](myrsi)[1] if a then myindex=barindex endif barHH=barindex[0]-myindex return barHH

  When it gives you 0, it means the highest or lowest value of RSI is in the current bar.

  barindex finder lowest RSI

  //RSI lowest low BARINDEX myrsi = rsi[14] c1=myrsi<lowest[250](myrsi)[1] if c1 then myindex=barindex endif barLL=barindex[0]-myindex return barLL

  1 2 3 4 5 6 7 8

  //RSI lowest low BARINDEX myrsi = rsi[14] c1=myrsi<lowest[250](myrsi)[1] if c1 then myindex=barindex endif barLL=barindex[0]-myindex return barLL

  I hope this can help you!

  Hello maximus78, your code is correct and working perfectly, thank you!

  I miss only one thing: how can I exclude from the calculation a certain number of latest bars? For example if I want to find the Bar Index of highest RSI of last 250 excluding last month (20 bars)?

  Thank you in advance

  Matteo

  ProScreen only supports the last 254 bars.

  Maximus78’s code should not work. It’s odd if it does!
