在价格坐标处绘制线的问题

Question

我正在写一个简单的指标显示垂直和水平线。垂直线应以纽约开盘价绘制我从时间戳比较中得到，但是 y 坐标线是不正确的。非常感谢任何帮助，因为我现在正在苦苦挣扎。

//@version=4
study("Sessions",overlay=true, scale=scale.none)
t1 = timestamp("GMT", year, month, dayofmonth, 0, 00, 00)
t2 = timestamp("GMT-5", year, month, dayofmonth, 0, 00, 00)

backLook = 86400000 * 1.5

displayCondition = timeframe.isdwm == false and (time > timenow - backLook)

vline(BarIndex, Color, LineStyle, LineWidth) => // Verticle Line, 54 lines maximum allowable per indicator
    return = line.new(BarIndex, -1000, BarIndex, 1000, xloc.bar_index, extend.both, Color, LineStyle, LineWidth)

drawPrice(price) =>
    x = bar_index
    y = price
    txt = tostring(price)
    label.new(x, price, txt)

    // y position is always wrong, the label text displays the correct price though
    line.new(x1=t2, y1=y, color=#ec4069, x2=time + 86400000, y2=y,xloc=xloc.bar_time)

// ny open
if(time == t2 and displayCondition)
    vline(bar_index, #ec4069, line.style_solid, 1)

if(time == t2 and displayCondition)
    drawPrice(open)

// gmt open
if(time == t1 and displayCondition)
    vline(bar_index, #000000, line.style_solid, 1)

问题的原因是'No Scale'模式。为了禁用该模式并解决问题，请从 study 调用中删除 scale 参数：

study("Sessions",overlay=true)
