//============ Webhook Alert Conditions ==================================//

关键转换说明 #

• 版本与语法更新：将版本声明改为//@version=5，所有技术分析函数（如crossover、ema）前添加ta.前缀，数学函数（如max、sqrt）前添加math.前缀
• 时间框架处理：使用input.timeframe()替代字符串输入，request.security()添加barmerge.lookahead_off避免未来函数风险，同时用syminfo.tickerid替换旧版tickerid
• Point & Figure适配：将字符串方法映射为V5的pf_type枚举，调整pointfigure()参数顺序符合新规范
• 变量持久化：Supertrend的TrendUp/TrendDown使用var关键字初始化，确保跨K线保留状态
• Alert配置：新增alertcondition()定义买卖信号触发规则，消息体采用JSON格式适配Pineconnector

Pineconnector Webhook配置步骤 #

1. 在TradingView中打开该策略，点击右上角「Alert」按钮
2. 触发条件选择「Any alert() function call」
3. 勾选「Webhook URL」，填写Pineconnector提供的MT5对接地址
4. 保存alert配置，确保Pineconnector已在本地运行并完成MT5授权
