Hi,

I’m trying to call a custom indicator function from a proscreener scan.

What I’m trying to do is to request a custom bar index in the past : for example the indicator result from 30 days ago (as it appears on the charts)…

I found the CustomClose parameter but it doesn’t seem to be working…

Is that even possible ?

So far I came up with this :

// Here I'm trying to get the result for my indicator "myCustomFunction" : 
// Today
// 10 days ago
// 20 days ago
// What the indicator does is not important in this example...
// Let's say it returns either 1 or 0, and here I'm trying to find stocks in which the indicator value was 1 on bars 0, 10, 20

score0 = CALL "myCustomFunction"(CustomClose[0])
score1 = CALL "myCustomFunction"(CustomClose[10])
score2 = CALL "myCustomFunction"(CustomClose[20])

score = score0 + score1 + score2

SCREENER[score = 3](score as "score")

I did not test it, but you can try

// Here I'm trying to get the result for my indicator : 
// Today
// 10 days ago
// 20 days ago
// The indicator doesn't matter in this example.
// Let's say it returns either 1 or 0, and here I'm trying to find stocks in which the indicator value was 1 on bars 0, 10, 20
 
MyScore = CALL "myCustomFunction"(CustomClose)
 
score = MyScore  + MyScore[10] + MyScore[20]
 
SCREENER[score](score as "score")
