For my scalping or Intraday trade, I created this pine script combining various indicator (namely the famous Alphatrend by KivancOzbilgic, Previous Day Close and 52WeeksHigh/Low) into one indicator.
If price goes above the PDC and Alphatrend is a buy then I will make quick long trade. If price goes below the PDC and Alphatrend is a sell then I will make quick short trade. I added a percentage based on PDC to give me where I need to put my stoploss. Not really important as I always have proper risk reward ratio but it comes handy most of the time.

It is not 100% foolproof but with proper RRR, pretty much you will be profitable.
