Widget-Constructor

You may specify Charting library widget parameters when calling its constructor. E.g., your call may look like

new TradingView.widget({
    symbol: 'A',
    interval: 'D',
    timezone: "America/New_York",
    container_id: "tv_chart_container",
    locale: "ru",
    datafeed: new Datafeeds.UDFCompatibleDatafeed("https://demo_feed.tradingview.com")
});

Find full supported parameters list below. Please remember that changing those parameters after chart is initialized does not work. If you want to change the state of a chart after it was initialized, use [[Widget methods|Widget-Methods]] instead.

Properties marked :chart: are available in [[Trading Terminal]] only.

symbol, interval [mandatory]

Initial symbol & interval of your chart. Format of interval is described in another [[article|Resolution]].

timeframe

Sets initial timeframe for the chart. Timeframe is period of bars that will be loaded and shown on a screen.
