how to create pine script indicator for only today

Question

my script is to take daily ATR and apply to todays 15 min chart using the ATR =/- from prev close a trading Range

I want it to be applied only to current day and not show the previous day because it just messes up the screen

please advice how to make it so that only next day levels are shown

CODE i am using --

timeFrame = input.timeframe(defval="D")
curratr=ta.atr(14)
atr=request.security(syminfo.tickerid,timeFrame,curratr[1])
prevClose = request.security(syminfo.tickerid,"D",close[1],gaps = 
barmerge.gaps_off, lookahead=barmerge.lookahead_on)
plot(prevClose+atr, color=color.red, linewidth=2)
plot(prevClose+atr*0.5, color=color.red, linewidth=2)
plot(prevClose, color=color.black, linewidth=2)
plot(prevClose-atr*0.5, color=color.green, linewidth=2)
plot(prevClose-atr,color=color.green, linewidth = 2)
