我正在尝试对 TradingView 中的官方枢轴点标准指标进行小修改，但在编码方面我有点新手，而且我尝试的所有方法似乎都不起作用。我什至尝试使用 ChatGPT 但没有成功。
在开市前交易时间内，直到市场开盘（东部时间上午 9:30）后才会绘制交易日的枢轴点水平。
由于枢轴点公式使用前一天的数据来计算新的枢轴水平，我正在尝试修改代码，以便在美国东部时间上午 9:30 之前的盘前交易时段绘制当天的数据。
任何帮助将不胜感激。谢谢你
下面的代码是 TradingView 中枢轴点标准指标的官方代码。

我尝试使用“request.security”，但这可能是错误的（使用 ChatGPT）。
localPivots = ta.pivot_point_levels(pivotTypeInput, localPivotTimeframeChange)
securityPivotPointsArray = ta.pivot_point_levels(pivotTypeInput, securityPivotTimeframeChange)
将这两个更改为开发模式
参见 ta.pivot_point_levels 进行参考
