TradingView脚本第3行报错：找不到'indicator'函数的技术问询

问题根源 #

• Pine Script v5 已废弃study()函数，所有脚本必须使用indicator()作为唯一的入口声明函数
• 你的脚本同时调用了indicator()和已失效的study()，导致编译器无法识别study()，进而触发报错

修复步骤 #

1. 删除第3行的study("Support Resistance Channels", "sr_channels", overlay = true, max_bars_back = 501)语句
2. 将study()中的配置参数合并到第2行的indicator()中，确保脚本声明符合v5规范

修复后的代码片段 #

//@version=5
indicator("Support Resistance Channels", "sr_channels", overlay = true, max_bars_back = 501)
