Need Help With Line Extension

I'm trying to get the line to touch the high and low of the candle with the line extending. Like the yellow line does at the mid-point of the candle. I know it's something simple, but I can't figure the code out.


Code: 
def last = if isnan(close[-2]) and !isnan(close) then barnumber() else last[1];
def hilo = if hl2 then barnumber() else hilo[2];

def cond = if barNumber() == hilo then barNumber()-2 else double.nan;
def pbar = if barNumber() >= HighestAll(cond) and !last then 2 else double.nan;

input show50 = yes;
plot HalfBack = if show50 and !isnan(pbar) then hl2 else double.nan;
HalfBack.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
HalfBack.SetDefaultColor(color.Yellow);
HalfBack.SetLineWeight(3);
def hbext    = if isnan(halfback) then hbext[1] else halfback;
plot hbextline = hbext;
hbextline.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
hbextline.SetDefaultColor(color.Yellow);
hbextline.SetLineWeight(3);

input show75 = yes;
plot Back75 = if show75 and !isnan(pbar) then low+(high-low)*.75 else double.nan;
Back75.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
Back75.SetDefaultColor(color.white);
Back75.SetLineWeight(1);

input show25 = yes;
plot Back25 = if show25 and !isnan(pbar) then low+(high-low)*.25 else double.nan;
Back25.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
Back25.SetDefaultColor(color.white);
Back25.SetLineWeight(1);

input bubblemover = 1;
def n1 = bubblemover + 1;
input showbubble_candle    = no;
input showbubble_expansion = no;
addchartBubble(showbubble_candle and barnumber()==highestall(last-1),high,"H: " +high,color.white,yes);
addchartBubble(showbubble_candle and barnumber()==highestall(last-1),low,"L: " +low,color.white,no);
addchartBubble(showbubble_expansion and isnan(close[bubblemover]) and !isnan(close[n1]),high[n1+1],"H: " +high[n1+1],color.white,yes);
addchartBubble(showbubble_expansion and isnan(close[bubblemover]) and !isnan(close[n1]),low[n1+1],"L: " +low[n1+1],color.white,no);
def h2 = if isnan(close) then h2[1] else high[2];
plot h2p = if barnumber()>=highestall(last) then h2 else double.nan;
h2p.setpaintingStrategy(PaintingStrategy.HORIZONTAL);
h2p.setdefaultColor(color.black);
input showcolor_light_gray = yes;
h2p.assignvalueColor(if showcolor_light_gray then color.black else color.black);
def l2 = if isnan(close) then l2[1] else low[2];
plot l2p = if barnumber()>=highestall(last) then l2 else double.nan;
l2p.setpaintingStrategy(PaintingStrategy.HORIZONTAL);
l2p.setdefaultColor(color.black);
l2p.assignvalueColor(if showcolor_light_gray then color.black else color.black);

The defs h and l and plots hh and ll should do that
