TradingView指標(程式碼)分享(1) UT Bot Alerts+STC Indicator+Hull Suite

 首先聲明，落魄其實並不會寫程式，一切都是誤會。

這次分享的是剝頭皮策略的指標合併，介紹YT：https://youtu.be/rOqCgwoTWCE

用到的指標分別是：

1.UT Bot Alerts

2.STC Indicator - A Better MACD [SHK]

3.Hull Suite

相關參數請看原YT

由於TradingView免費版一次只能用三個指標，落魄將三個指標合併成一個指標，並依影片參數修改，最難搞的是STC，原始程式碼似乎故意讓人看不懂，都是AAABBB代碼。

買賣信號各有兩種

一般Buy、Sell，是指收盤價在Hull Suite之上或之下。

Buy!、Sell!，是指開盤價(整根K棒)在Hull Suite之上或之下。

並增加一條200EMA線。

快訊也有分Buy、Sell、Buy!、Sell!
