Tradingview 小部件 - 自定义简单移动平均线和指数移动平均线长度

Question

I'm trying to add "Advanced Real Time chart" widget from tradinview. I'm able to add indicator Exponential moving average and Simple moving average. But it takes default 9 days length. I want to change that.

I tried as below but it does not work. Could somebody please help. Thanks a lot in advance.

widget = new TradingView.widget(
    {
        "width": 1200,
        "height": 700,
        "symbol": "NSE:DRREDDY",
        "interval": "D",
        "timezone": "Asia/Kolkata",
        "theme": "Dark",
        "style": "1",
        "locale": "in",
        "toolbar_bg": "#f1f3f6",
        "enable_publishing": false,
        "hide_side_toolbar": false,
        "allow_symbol_change": true,
        "details": true,
        "studies_overrides": {
            "moving average exponential.length": 20
        },
        "studies": [
            "MAExp@tv-basicstudies"
        ],

        "container_id": "tradingview_f6d89"
    }

Answer 1

Here's the way to do it :

"studies": [
   {
     "id": "MAExp@tv-basicstudies",
     "version": 60,
     "inputs": {
       "length": 20
     }
   },
   ...

上面的代码在当前时间范围 (TF) 上取 EMA 20滴答，所以如果你想要天，你需要将 TF 设置为days并将此值更改为9 （或等效地，将 TF 设置为小时并将 EMA 设置为24*9 ）。
