Franchissement support / résistance

Bonsoir,

je souhaiterais à partir de l’indicateur ci-dessous avoir un screener qui identifie le franchissement des lignes hband (à la hausse) ou lband (à la baisse).

upward = upward[1]+1
elsif filt < filt[1] then

downward = 0
If filt < filt[1] then
downward = downward[1]+1
elsif filt > filt[1] then
downward = 0
else
downward = downward[1]

// Target Bands
hband = filt + smrng
lband = filt – smrng

colorbetween(lband,hband,red,Green,Blue,88)

if islastbarupdate then
if close<hband then
DRAWSEGMENT(barindex, hband, barindex+5, hband)style(line,2) coloured(0,0,200)
endif
if close>lband then
DRAWSEGMENT(barindex, lband, barindex+5, lband)style(line,2) coloured(0,0,200)

Return filt as “Range Filter”, hband as “High Target”, lband as “Low Target”, mbtendance as “tendance”
