如何使用pine代码在使用for循环的交易视图中绘制圆圈

circleRadius = 10

//@version=4
study("Circle Drawing Example", overlay = true)

circleRadius = 10

// 遍历每个交易数据点
for i = 0 to bar_index
    // 计算圆圈的X坐标和Y坐标
    x = time[i]
    y = close[i]

    // 在每个数据点的位置上绘制一个圆圈
    plotshape(series = i, title = "Circle", style = shape.circle, location = location.absolute, color = color.blue, size = circleRadius, transp = 0)
    
    // 可以使用plot函数在圆圈上标注一些文本信息
    // plot(series = i, title = "Text", text = tostring(i), color = color.white, style = text.style_labelup)
