How can i draw the horizontal lines on pine script for particular candle?

//@version=4
//@WMSIDI

study(title = "Engulfing Lines", overlay = true)

// bullish engulfing (alpha)
alpha = open[3] > close[3] ? open[2] > close[2] ? open[1] > close[1] ? close > open ? close >=open[1] ? close[1] >= open ? close - open > open[1] - close[1] ? color.yellow :na :na : na : na : na :na :na

barcolor(alpha)

plot(close, "Line", color.lime, 2, plot.style_line, true, show_last=1)
plot(open, "Line", color.blue, 2, plot.style_line, true, show_last=1)

enter image description here

I have added the image that is generated after running this script for bullish engulfing candle. I wanna draw horizontal lines on open and close of each detected bullish engulfing candle. How can we do that?

You can use the line feature for that. There are some limitations.

//@version=4
//@WMSIDI

study(title = "Engulfing Lines", overlay = true)

// bullish engulfing (alpha)
eng = open[3] > close[3] and open[2] > close[2] and open[1] > close[1] and close > open and close >=open[1] and close[1] >= open and close - open > open[1] - close[1]
alpha = eng ? color.yellow :na

barcolor(alpha)

var line l_close = na
var line l_open = na
l_close_level = close
l_open_level = open

if eng
    line.set_x2(l_close, bar_index)
    line.set_extend(l_close, extend.none)
    line.set_x2(l_open, bar_index)
    line.set_extend(l_open, extend.none)
    l_close := line.new(bar_index, l_close_level, bar_index, l_close_level, extend=extend.right, width=2)
    l_open := line.new(bar_index, l_open_level, bar_index, l_open_level, extend=extend.right, width=2)
