Pine脚本-在任何先前会话的特定时间范围的最高处绘制水平线，而与当前会话无关

//@version=4
study("Draw Horizontal Line at Highest Point of Specific Time Range", overlay=true)

// 定义需要绘制水平线的时间范围
start_time = timestamp(2022, 1, 1, 0, 0)
end_time = timestamp(2022, 12, 31, 23, 59)

// 查找时间范围内的最高价和对应的时间
highest_high = high
highest_time = na
if time >= start_time and time <= end_time
    highest_high := high > highest_high ? high : highest_high
    highest_time := high > highest_high ? time : highest_time

// 绘制水平线
line.new(x1=highest_time, y1=highest_high, x2=end_time, y2=highest_high, color=color.blue, width=1, extend=extend.right)

// 输出结果
plot(highest_high, title="Highest High", color=color.blue, linewidth=2)
