PineScript 从 v3 到 v4 - "is already defined" 重新分配问题
PineScript from v3 to v4 - "is already defined" Reassignment problem
我正在尝试将下面的脚本从 Pine Script 版本 3 转换为版本 4。但是，我收到一条错误消息，提示编译失败，第 28:30 行：“obv”已定义。我试图在分配函数 (=>) 之前在 obv(src) 上添加重新分配运算符 (:=)，但它没有用。有人知道如何解决这个问题吗？
谢谢

Pine V4 有自己的内置函数 obv()。因此，您必须将 obv() 重命名为 obv_f()，或者删除此函数并使用内置的

将其转换为 V5 也很有意义。
我正在尝试将下面的脚本从 Pine Script 版本 3 转换为版本 4。但是，我收到一条错误消息，提示编译失败，第 28:30 行：“obv”已定义。我试图在分配函数 (=>) 之前在 obv(src) 上添加重新分配运算符 (:=)，但它没有用。有人知道如何解决这个问题吗？
