// ======================== 备注 ========================
|
||||
// 1) 当前周期通过 timeframe.period 自动识别，并用 timeframe.in_seconds(
|
||||
// ) 转换成秒以进行相对大小比较。
|
||||
// 2) 长级别/次级别集合从标准分辨率表中过滤得出，绘图数量受 MAX_* 与输入上限控制。
|
||||
// 3) 虚线效果通过在 plot 中周期性输出 na 实现，性能优于逐柱绘制 line 对象。
|
||||
// 4) 标签在最后一根柱更新，避免过量对象；颜色与曲线一致。
|
||||
// 5) 次级别（低于当前）EMA52 也计算并显示，更新频率更高，默认更淡。
