交易视图图表集成的数据格式

I am trying clone the trading view chart api. I have checked the github sample that they have provided and found the following code:

  var _datafeed = new Datafeeds.UDFCompatibleDatafeed("http://yourhost/tradingview", 10000);
        var _widget = window.tvWidget = new TradingView.widget({
          symbol: 'AAPL',
          fullscreen:true,
          interval: '15',
          container_id: "tv_chart_container",
          datafeed: _datafeed,
          library_path: "/charting_library/",
          locale: getParameterByName('lang') || "en",
          disabled_features: ["use_localstorage_for_settings", "header_symbol_search", "symbol_search_hot_key"],
          debug: false,
          overrides: {
            "paneProperties.background": "#222222",
            "paneProperties.vertGridProperties.color": "#454545",
            "paneProperties.horzGridProperties.color": "#454545",
            "symbolWatermarkProperties.transparency": 90,
            "scalesProperties.textColor": "#AAA"
          }
        });

I understand that the data that is provided is given from url "http://yourhost/tradingview".Can anyone help me to find the format of data that is provided from that url. Thanks in advance

in component.ts use this code

customFormatters: {
    dateFormatter: {
      format: function (date) {
        var days = ["شنبه", "یکشنبه", "دوشنبه", "سه شنبه", "چهارشنبه", "پنجشنبه", "جمعه"],
          year = date.getUTCFullYear(),
          month = date.getUTCMonth() + 1,
          day = date.getUTCDate(),
          result = day + "-" + month + "-" + year;
        return days[date.getUTCDay() - 1] + " " + result;
      }
    }
  }

And Also use plugin.js for persiandate
