 // init must be called before anything else.
 wtcharts.init({
    appId: 11,
    lang: 'en',
    server: 'wss://ws.binaryws.com/websockets/v3'
 });
 // supported langauges are [ 'ar', 'en', 'de', 'es', 'fr', 'id', 'it', 'pl', 'pt', 'ru', 'th', 'vi', 'zh_cn', 'zh_tw']
 
 const chart =  wtcharts.chartWindow.addNewChart($parent, {
    "type": "line",
    "timePeriod": "1m",
    "instrumentCode": "RDBULL",
    "instrumentName": "Bull Market Index",
    "showInstrumentName": true, // default is false
    "showOverlays": false, // default is true
    "indicators": [
       {
          "id": "cks",
          "name": "Chande Kroll Stop",
          "options": {
             "period": 10,
             "maxMinPeriod": 20,
             "multiplier": 3,
             "longStopStroke": "#00C176",
             "shortStopStroke": "#FF003C",
             "strokeWidth": 1,
             "dashStyle": "Solid"
          }
       },
    ],
    "overlays": [ ],
 });

 // Will be called every time user makes a change
 chart.events.anyChange = () => {
    console.warn(chart.data());
    // Pass chart.data() to addNewChart() to restore a chart.
 }; 

 chart.actions.reflow(); // Resizes the chart, call it when container is resized.
 chart.actions.refresh(); // Refreshes the entire chart.
 chart.actions.destroy(); // Destroys the chart. returns a promise.
