Hi Nicolas, awesome work for creating the Indictor of RSI and Linear Regression trading signals!
By any chance, do you have the Screener version for this “RSI and Linear Regression trading signals”?
I tried to convert the indicator to screener by replacing the drawing at the end i.e. “SCREENER[Signal](Signal AS “1=↑, 2=↓”)”, where I use the Signal =1 or 2 to replace the two condition of drawing in the codes … but at the end I always get the error “Syntax error: This variable is not used in the {did not show any further info}”.
The Screener would complete your indicator perfectly if you can add the screener here for us.
Thank you for the great work guiding us through, as always!

Hi Manafull,
You can combine the indicators in different ways, I don’t know exactly what you want but here is an example of the RSI (30/70) in combination with the Linear Regression slope…
myRSI=RSI[14](Close)
C1=myRSI Crosses Over 30 //Buy signal
C2=myRSI Crosses Under 70 //SellShort signal
myLRS = LinearRegressionSlope[10](close)
C3=myLRS > 0 //Buy signal
C4=myLRS < 0 //SellShort signal
If C1 and C3 then
Trend=1
ElsIf C2 and C4 then
Trend=-1
EndIf
C5=Close>10
SCREENER [C1 and C3 and C5 or C2 and C4 and C5] (Trend AS "Trend")
Hi JS
Thanks for that and I will try yours and report back here..
In the meantime, the screener that I wanted to get to, is the indicator from Nicolos’s
indicator that I wanted to convert into a screener… below is code I tried to run but always with the error ““Syntax error: This variable is not used in the {did not show any further info}”.”:
// --- settings
len = 21 //RSI Length
period = 200 //Period
deviations = 2.0 //Deviation(s)
// --- end of settings
//extra for screener
Signal = 0
irsi = rsi[len](close)
periodMinusOne = period-1
Ex = 0.0
Ey = 0.0
Ex2 = 0.0
Exy = 0.0
for i=0 to periodMinusOne
closeI = (irsi[i])
Ex = Ex + i
Ey = Ey + closeI
Ex2 = Ex2 + (i * i)
Exy = Exy + (closeI * i)
ExEx = Ex * Ex
next
//slope
if Ex2=ExEx then
slope = 0.0
else
slope= (period * Exy - Ex * Ey) / (period * Ex2 - ExEx)
endif
ilinearRegression = (Ey - slope * Ex) / period
intercept = ilinearRegression + barindex * slope
deviation = 0.0
for i=0 to periodMinusOne
deviation = deviation + square((irsi[i]) - (intercept - slope * (barindex[i])))
next
deviation = deviations * sqrt(deviation / periodMinusOne)
startingPointY = ilinearRegression + slope / periodMinusOne
//lineColor
//if startingPointY > startingPointY[1] then
//color.blue
//r=0
//b=255
//else
//color.red
//r=255
//b=0
//endif
a = startingPointY-deviation
c1 = startingPointY
b = startingPointY+deviation
up=irsi crosses over a
down=irsi crosses under b
if up then
//drawtext("↑ up",barindex,irsi-5,dialog,standard,20) coloured(0,255,0)
Signal = 1
endif
if down then
//drawtext("↓ down",barindex,irsi+5,dialog,standard,20) coloured(255,0,0)
Signal = 2
endif
SCREENER[Signal](Signal AS "1=↑, 2=↓")
If you or Nicolas can review the above code and rectify it, that would be awesome. In the meantime, I will try your (JS) code as above.
Thanks!
Hi JS, I just run your screener and it gives me some from NASDAQ. What I wanted is to see the list of the candidates who are at the signaling point either about to dive or taking off from the RSI perspective.
If you look at Nicolas’s indicator, it shows all those:
https://www.prorealcode.com/prorealtime-indicators/rsi-and-linear-regression-trading-signals/
My above code is trying to convert Nicolas’s indicator into the Screener. It should not be difficult but I keep getting the syntax error.
Here is a working version to check for those RSI breakout of its linear regression channel with a screener.

screener[up or down]
Thank you so much Nicolas!!!!
I just run it and it is brilliant – exactly what I am after!
The only thing I need to accommodate to run the code at my end is to clean up my PC memory and make more room to run this screener, as it is taking some time to return the results, which are all gold to me.
Just can’t thank you enough 👍👍👍
