松脚本绘图线连接两条线

Question

我有一个代码可以根据白天形成高点或低点的时间从高点到低点或从低点到高点画线。我想有一条连接线到每一天的线。怎么办。

study(title="Neely Charts", overlay=true)
//Define variables
string      res = input("D")
var float   h_price = na
var float   l_price = na
var int     h_date = na
var int     l_date = na
var float   h1_price = na
var float   l1_price = na
var int     h1_date = na
var int     l1_date = na



var line z = na
bool isnewtbar = change(time(res)) > 0

//getting lines
if isnewtbar and bar_index > 1 
    h_price := high
    l_price := low
    h_date := time
    l_date := time
   
    z := line.new(x1=h_date, y1=h_price, x2=l_date, y2=l_price, xloc=xloc.bar_time, extend=extend.none, color=color.black, style=line.style_solid, width=2)
    


if high > h_price
    h_price := high
    h_date := time 


if low < l_price
    l_price := low
    l_date := time
  

if h_date <= l_date
    // high to low
    line.set_xy1(id=z, x=h_date, y=h_price)
    line.set_xy2(id=z, x=l_date, y=l_price)
    line.set_color(id=z, color=color.red)
    
else
    // low to high
    line.set_xy1(id=z, x=l_date, y=l_price)
    line.set_xy2(id=z, x=h_date, y=h_price)
    line.set_color(id=z, color=color.lime)

我尝试设置前几天的价格但无法继续。有人能帮忙吗
