Pine Script v5中获取指定标签UNIX时间及解决时间显示异常

你遇到的1969-12-31 19:00是因为**label.get_x()返回的是K线的索引值，不是UNIX时间戳**。str.format_time()需要的是毫秒级UNIX时间（对应Pine里的time变量），而小数值的bar索引会被解析为UNIX纪元初期的时间（时区偏移导致显示1969年底）。

不要通过标签获取时间，而是在检测到枢轴高点/低点时直接记录对应的时间戳，和枢轴价格同步存储。

关键修改点 #

• 添加变量存储枢轴对应的时间戳：ph_time0、ph_time1、ph_time2
• 在检测到新的枢轴高点时，同步记录枢轴实际出现K线的时间（time[rightLenH]，因为ta.pivothigh在右侧满足条件时才确认枢轴）
• 用存储的时间戳调用str.format_time()生成正确的日期时间

说明 #

• 当ta.pivothigh返回非NA值时，枢轴高点实际出现在bar_index[rightLenH]的位置，因此对应的时间是time[rightLenH]
• 时间戳变量与价格变量同步更新，确保时间和枢轴价格一一对应
• 格式化时间时增加非零判断，避免初始状态显示无效内容
