Pine Script追踪止损警报执行问题求助及代码修正

问题1：警报触发延迟 #

原因 #

原代码依赖strategy.closedtrades判断平仓事件，该API仅在K线闭合后才会记录平仓数据，导致警报滞后于图表上的平仓信号（紫色箭头）。

修复方案 #

直接在K线实时更新时监控止损/追踪止损的触发条件，一旦价格触及止损线或追踪止损线，立即触发警报，无需等待K线闭合。

问题2：平仓注释无法区分类型 #

原因 #

原代码未给止损（Stop Loss）和追踪止损（Trailing Stop）的平仓操作设置差异化注释，导致两类平仓的注释均显示为"Trailing"。

修复方案 #

在strategy.exit函数中，分别通过comment_stop和comment_trail参数为止损、追踪止损设置独立注释，明确区分平仓类型。

问题3：空头计数器异常 #

原因 #

原代码仅在反向开仓（Cross）平仓时更新shortCerrado变量，止损/追踪止损平仓时未同步更新该变量，导致始终使用初始值（或旧值），交易编号固定为1。

修复方案 #

在监控到止损/追踪止损触发时，立即将shortCerrado赋值为当前持仓的shortEnCurso，确保交易编号与对应持仓匹配。
