Can Anyone create this Trendline Indicator?

Hi,

Can someone create an indicator that draws a trendline from the open of the 0:00 candle the open of the 7:30 candle every day?

I also want the each trendline to stop at 23:55 instead of extending to infinity.

Or can anyone point me to information about creating an indicator that draws trendlines from one specific time to another?
