Hey Guys,

I need some help for a screening idea.

The screener has to show me all stocks (or other things) where the high fractal is 5 candles in the past.

I used this indicator code

// Visualisation des fractales avec flèches
Arrow = 0
 
// Nombres de bougies constituant la fractale (impair)
Ncandles = 5
 
// Nombres de bougies de chaque côté de la bougie extrême
Nside = (Ncandles - 1) / 2
 
// Définition de la fractale supérieure
IF high[Nside] >= highest[Ncandles](high) THEN
Fup = high[Nside]
Arrow = -1
ENDIF
 
// Définition de la fractale inférieure
IF low[Nside] <= lowest[Ncandles](low) THEN
Fdown = low[Nside]
Arrow = 1
ENDIF
 
// Tracé des flèches
IF Arrow = 1 THEN
DRAWARROWDOWN(barindex[2],low[2]-Averagetruerange[5]/3)coloured(255,0,0)
ELSIF Arrow = -1 THEN
DRAWARROWUP(barindex[2],high[2]+Averagetruerange[5]/3)coloured(0,150,0)

ENDIF
 
Return Fup as "Fractale UP", Fdown as "Fractale DOWN"

Dropped the drawing code, so it looked at the end like this:

// Visualisation des fractales avec flèches
Arrow = 0
 
// Nombres de bougies constituant la fractale (impair)
Ncandles = 5
 
// Nombres de bougies de chaque côté de la bougie extrême
Nside = (Ncandles - 1) / 2
 
// Définition de la fractale supérieure
IF high[Nside] >= highest[Ncandles](high) THEN
Arrow = -1
ENDIF
 
// Définition de la fractale inférieure
IF low[Nside] <= lowest[Ncandles](low) THEN
Arrow = 1
ENDIF

// Beispielcode Screener
SCREENER[Arrow[5] = 1]

So problem is: it does not work. Is anybody out there who can tell me what I am doing wrong? 🙂

This is the code that should work in this case:

// Nombres de bougies constituant la fractale (impair)
Ncandles = 5
 
// Nombres de bougies de chaque côté de la bougie extrême
Nside = (Ncandles - 1) / 2
 
// Définition de la fractale supérieure
fractal = high[Nside] >= highest[Ncandles](high) 
 


// Beispielcode Screener
SCREENER[fractal[5]]

Bear in mind that Fractals appear on candlesticks in the past, so even scanning a fractal occurrence 5 bars ago doesn’t mean that the fractal will be displayed 5 bars ago from the current bar.
