NT8 Repeat Vertical line (X time), High Low indicator (X Time)

Hi All,
I am looking for NT8 indicators
(1) the first indicator should draw a vertical line in the given input time (example 20 minutes).
(2) The second indicator I am looking for should draw a horizontal line on the high and low prices within a set time frame (eg: 20 minutes as above).

Basically I need a box, the vertical should repeat every X minutes and the horizontal line should be drawn on High and Low of the the above time . I see a indicator to draw vertical line but it is NT7. I need NT8

Thanks for the help.
