This indicator is made for educational and study purposes only. The reason I made this script was to have open price lines which are able to be customized to your preferred timeframe. You can go to the settings and select your timeframe and the indicator will draw out the line with a text label.
Timeframes: - 5m - 15m - 30m - 1h - 2h - 4h - 8h
I also made sure to have the options to draw out the daily, weekly, and monthly open so you don't have to add another script. Planning to add NY-midnight open and 08.30 open in the next update
