Bar Index – Proscreener

hamid1736 · 2017-10-28T15:08:23+00:00

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:
```
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
```
```
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]
```

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:
```
//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.
```
//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!
