Trend change indicator. I need help adjusting the plot.

[Haamu]

I have built an indicator when a candle changes trend. The plots work fairly well.
I am looking to have the lines extend all the way to the end of the chart and then have the lines stop or go dashed when a candle closes through (not on wicks) preferably a toggle if possible. Thanks in advance!
