Plot Current Live Price Horizontal Line - not at close of current bar regardless of timeframe

[DJones]

I cannot find a horizontal current price line that actually updates with live data. Everything seems to use a closing price for a bar. I want a live price bar regardless of timeframe on the chart.

Please help!

Thank you so very much! The first one appears to be working. I look forward to watching it react during regular trading hours. This was my first question on the site and I really appreciate the reply and help.
