Someone already made one on TV. Just search "RDR" in the indicators and pull up the indicator by tyntrade. The script is protected so I can't see what it is doing, but you can see if it is giving you what you think it should on the charts. I don't trade that pattern so I haven't noticed how good it works in realtime. I noticed there is a second script by someone else that says intra day. It wasn't there when I found this one awhile back.
