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!

here is one way to draw a line that changes to a dash, when it crosses a bar body.
it will also change to a dash if it passes through a gap in bars.
it starts drawing a line at some barnumber. change it so it is near a lowest low.
if it crosses the next bar, then you won't see any solid line, it will change to dash right away.

i didn't do anything with your study. if you want multiple lines to exist on a bar, you will need a plot formula for each line and all the supporting formulas. so if you want 10 lines, you will need 10 copies of this study.

# bar_cross_line_dash

def na = double.nan;
def bn = barnumber();

# define start of a horz line
#input line_start_bn = 104;
input line_start_bn = 116;
input price = low;

def bodytop = max(open,close);
def bodybot = min(open,close);

def line1 = if bn == 1 then na
 # start defining a line
 else if bn == line_start_bn then price
 else if isnan(close) then na
 # chk for bar crossing line, chg to neg #
 else if bodytop > line1[1] and bodybot < line1[1] and line1[1] > 0 then -line1[1]
# test if line goes thru a gap in bars
 else if (bodybot[1] > line1[1] and bodytop < line1[1]) or (bodytop[1] < line1[1] and bodybot > line1[1]) then -line1[1]
 else line1[1];

# plot solid line from a bar
plot z1 = if line1 > 0 then line1 else na;
z1.SetDefaultColor(Color.yellow);
#z1.setlineweight(1);
z1.hidebubble();

# plot a dash line after crossing a bar 
plot z2 = if line1 < 0 then -line1 else na;
z2.SetStyle(Curve.MEDIUM_DASH);
z2.SetDefaultColor(Color.cyan);
z2.hidebubble();

addchartbubble(0, low,
 (bodybot[1] > line1[1] and bodytop < line1[1]) + " BT\n" +
 (bodytop[1] < line1[1] and bodybot > line1[1]) + " TB"
, color.yellow, no);
