Pine 编辑器不执行策略。即使应该关闭订单

Question

我正在使用 Pine 编辑器在 TradingView 上测试随机策略。我让代码在 K 线穿过 D 线并且 K < 20. It should exit the long trade when the K line crosses under the D line. It should enter a short trade when the K line crosses under the D line and K > 80 时执行多头入场。当 K 线穿过 D 线时，它应该退出空头交易。

问题：有时应该退出交易，但事实并非如此。例如，当K线穿过D线并且K > 80时，它将进入空头交易，但几个柱之后K线将再次穿过D线，但空头交易不会平仓。我在这里看到了另一篇文章，他们建议使用：close_entries_rule="ANY"。然而，这导致了很多订单立即打开和关闭的问题。

这是完整的代码，感谢您在解决问题时提供任何帮助！

Answer 1

忽略注释行 - 您编码为仅在会话结束时关闭交易 -

if not (session_open)
    strategy.close("Long")
    strategy.close("Short")

1. 为了结果的一致性，应在全局范围内调用函数（

   crossover

   ，

   crossunder

   ）
2. 将

   isLongEntry

   和

   isShortEntry

   转换为变量而不是函数，并添加

   strategy.close

   以及

   isLongExit

   和

   isShortExit

   参数。
3. 添加了背景颜色以识别活动会话。
