is it possible to program a screener for this indicator

bollingerLengths=50
liqLength=50
rocCalcLength=30
avg = average[bollingerLengths]
upBand = avg+std[bollingerlengths]*1.25
dnBand = avg–std[bollingerlengths]*1.25
atr = AverageTrueRange[14](close)
rocCalc = Close – Close[rocCalcLength–1]// {remember to subtract 1}
if(lastsignal<=0 and rocCalc > 0) and close<upBand then
drawarrowup(barindex,low–atr) coloured(0,255,0)
lastsignal=1
endif
if(lastsignal>=0 and rocCalc < 0) and close>dnBand then
drawarrowdown(barindex,high+atr) coloured(255,0,0)
lastsignal=–1
endif
if lastsignal=0 then
liqDays= liqLength
else
liqDays= liqDays – 1
liqDays= Max(liqDays,10)
endif
return

thanks

Since you wrote in english I moved this topic to the english forum.

To write code, please use the <> “insert PRT code” button, to make code easier to read. Thank you.

This is your screener:

bollingerLengths=50
liqLength=50
rocCalcLength=30
avg = average[bollingerLengths]
upBand = avg+std[bollingerlengths]*1.25
dnBand = avg–std[bollingerlengths]*1.25
//atr = AverageTrueRange[14](close)
rocCalc = Close – Close[rocCalcLength–1]// {remember to subtract 1}
if(lastsignal<=0 and rocCalc > 0) and close<upBand then
//drawarrowup(barindex,low–atr) coloured(0,255,0)
lastsignal=1
endif
if(lastsignal>=0 and rocCalc < 0) and close>dnBand then
//drawarrowdown(barindex,high+atr) coloured(255,0,0)
lastsignal=–1
endif
if lastsignal=0 then
liqDays= liqLength
else
liqDays= liqDays – 1
liqDays= Max(liqDays,10)
endif
screener[lastsignal]

You can change what the screener should search for.
