Bonjour et merci pour cet indicateur.
Toutefois, il me semble qu’il est unidirectionnel.
Par exemple ce matin 8 mars, sur un graphe CFD Dax en 5 min (10 unités), il devrait avoir changé d’orientation en passant d’une orientation haussière à une orientation baissière.
Il est finalement resté en orientation haussière toute la matinée.
Nicolas, pouvez vous me confirmer qu’il y a effectivement un souci please ?
Merci
Hi Choliver, you are right, there is a problem with the drawing instruction when the slope is = 0 THEN
y1 = LinRegres – ((LinRegPeriod-1)*LinRegresSlope)
ELSE
y1 = LinRegres – ((LinRegPeriod-1)*LinRegresSlope)
ENDIF
with :
y1 = LinRegres – ((LinRegPeriod-1)*LinRegresSlope)
I’ll ask Nicolas to update the code.
File and code are updated.
Hi allo
I am not sure I am doing it correctly, but this adds to proreal as an indicator. How to ad it as a study, so it would draw lines on the chart?
Hi,
when I copy the code, i get an error message that
LinRegPeriod is not defined.
Does anyone know how to solve that?
