var line extend right but cut off on candle

I created a intraday fibonnaci but just stuck on the var line as I'm new to using var line and have been using plot instead.

I'm trying to get the line to cut off at the candle and only extend when a new candle is from, I am using extend to right at the moment which gives me the below result

[Extend Right][1]: https://i.stack.imgur.com/VggLQ.png

Without extend right, it looks like this

[no extend right][2]: https://i.stack.imgur.com/wt3jf.png

Is there a way for the line to create itself and stop at the last candle and update once a new candle is form?

This is possible using chart.right_visible_bar_time. I updated the following line of your code and it seems to be working as you desire now.

f_moveLine(_line, _x, _y) =>
    line.set_xy1(_line, _x,   _y)
    line.set_xy2(_line, chart.right_visible_bar_time, _y)
