Hi,
i get this error when trying to run this as a MTF screener. It works without MTF
This ProScreener market scan cannot be executed because there is an infinite loop within the program code.
An infinite loop is a sequence of instructions which repeats itself endlessly when the code is executed. This may happen if:
– the loop doesn’t have a termination condition
– the termination condition can never be met
– the termination causes the loop to start over
To run the scan, modify the code of your ProScreener.

Hmm, that’s a lot of loops for ProScreener! 😳
So your problem is not related to the original code, but with your custom version of it!
You say it works without MTF, but on a single timeframe, right?
This indicator is the same as this simple code:
i = rsi[21]
lr = LinearRegression[200](i)
up=lr+std[200](i)*2
dn=lr-std[200](i)*2
return i,lr,up,dn
So that you can get rid of loops and make a MTF screener with ease!
bonjour
Je n’arrive pas à créer le Screener qui me permettrais de faire ressortir les signaux de retour dans les LinearRegression[200]
Ce premier indicateur (https://www.prorealcode.com/prorealtime-indicators/rsi-and-linear-regression-trading-signals/) qui donne la même chose que le votre ci-dessus indique des signaux.
Ces signaux sont bien souvent de bonne qualité en daily sur les titres en tendance, et j’aurais aimer un screener qui les filtres.
Mais malgré mes nombreux tests, rien de concluant!
Merci d’avance
hello I can not create the Screener that would allow me to bring out the return signals in the LinearRegression [ 200 ] This first indicator (https://www.prorealcode.com/prorealtime-indicators/rsi-and-linear- regression-trading-signals /) which gives the same as yours above indicates signals. These signals are often of good quality daily on trending titles, and I would like a screener who filters them. But despite my numerous tests, nothing conclusive! thank you in advance

Only post in the language of the forumthat you are posting in. For example English only in the English speaking forums and French only in the French speaking forums.
excuse me for this mistake
Unless I am mistaken, the screener you are trying to do (crossing upper and lower bounds of the linear regression channel applied to the RSI), must be this:
i = rsi[21]
lr = LinearRegression[200](i)
up=lr+std[200](i)*2
dn=lr-std[200](i)*2
test = i crosses over up or i crosses under dn
screener[test]
Hello I tried to modify your screener to bring out the stocks whose rsi went below Linear Regression and which started to rise again with a change of Heikin ashi candle from red to green.
Or perhaps more simply, the price of which has fallen below Linear Regression and which reclassifies it with a change of the HH candle from red to green.
here is the screener I wrote, but it doesn’t return anything to me?
sorry for my english, google translate…
Thank you in advance for your help.
cordially
i = rsi[21]
lr = LinearRegression[200](i)
dn=lr-std[200](i)*2
test = i crosses under dn
c2 = average[100](close) > average[200](close)
xClose = (Open+High+Low+Close)/4
if(barindex>2) then
xOpen = (xOpen[1] + xClose[1])/2
endif
c3 = xClose>xOpen AND xClose[1]<xOpen[1]
screener[test and c2 and c3]
