Could someone in this forum please write an indicator that I'd like to put on the hourly charts, to show the following?

- a DarkViolet solid vertical line (width 1) on all grid lines whose time is 19:00 [my broker's time that corresponds to the opening of the Tokyo session]

- a DodgerBlue solid vertical line (width 1) on all grid lines whose time is 3:00 [my broker's time that corresponds to the opening of the London session]

- a Yellow solid vertical line (width 1) on all grid lines whose time is 8:00 [my broker's time that corresponds to the opening of the NY session]

- a Red solid vertical line (width 1) on all grid lines whose time is 17:00 [my broker's time that corresponds to the close of the NYsession]

I appreciate your help!

Thank you!!
