Need a little TOS codeing help

I want to connect two points (trendline) on a lower study. Can't seem to figure it out. I keep getting two flat lines rather than an intergrated signal. Any help is appreciated.

input Channel_Length = 10;
input Average_Length = 21;

input over_bought_2 = 53;
input over_sold_1 = -60;
input over_sold_2 = -53;
input show_bubbles = yes;
input show_sec_bbls = no;
input show_alerts = yes;
def ap = hlc3;
def esa = ExpAverage(ap, Channel_Length);
def d = ExpAverage(AbsValue(ap - esa), Channel_Length);
def ci = (ap - esa) / (0.015 * d);
def tci = ExpAverage(ci, Average_Length);
def wt1 = tci;
def wt2 = SimpleMovingAvg(wt1, 4);

def green = if wt1 > wt1[1] AND wt1[1] <= wt1[2] then 1 ELSE 0;
def red = if wt1 < wt1[1] AND wt1[1] >= wt1[2] then 1 ELSE 0;

plot wt1_1 = wt1;
wt1_1.SetStyle(Curve.POINTS);
wt1_1.AssignValueColor(if green then (CreateColor(55, 251, 55)) else if red then (CreateColor(255, 0, 0)) else (color.gray));
wt1_1.SetLineWeight(5);
