我正在尝试将用Pinescript V2编写的指标转换为V3 / 4（我知道我可以先将其转换为V3，然后使用内置的“转换为V4”选项）。我还知道，必须先定义V2以外的变量，然后才能对其进行引用。
实际上，该指标在这些变量的定义内引用了一些变量。我已经成功地成功格式化了其中两个（“ greatstrange”和“ smoothedlocation”），但是我不知道如何重新格式化“ extmapbuffer”和“ extmapbuffer1”。另外，当我尝试在V3中运行脚本时，“ pricelocation”被认为是“未声明的变量”。它不是自指的，所以我不太确定为什么V3不喜欢它。
无论如何，在此先感谢您提供的所有帮助！
