Tradingview Drawing

Question

I'm using Tradigview Chart Widget to display data. I can't find a way to draw lines(or something else) on chart, and to save the drawings in order to display them when the page reloads.

<!-- TradingView Widget BEGIN -->
<div class="tradingview-widget-container">
    <div id="tradingview_6fd01"></div>
    <div class="tradingview-widget-copyright"><a href="https://www.tradingview.com/symbols/NASDAQ-AAPL/" rel="noopener" target="_blank"><span class="blue-text">AAPL chart</span></a> by TradingView</div>
    <script type="text/javascript" src="https://s3.tradingview.com/tv.js"></script>
    <script type="text/javascript">
        new TradingView.widget({
            "width": 980,
            "height": 610,
            "symbol": "NASDAQ:AAPL",
            "interval": "D",
            "timezone": "Etc/UTC",
            "theme": "Light",
            "style": "1",
            "locale": "en",
            "toolbar_bg": "#f1f3f6",
            "enable_publishing": false,
            "allow_symbol_change": true,
            "container_id": "tradingview_6fd01"
        });
    </script>
</div>
<!-- TradingView Widget END -->

Answer 1

For anyone who wants to draw on Widget but is not dependent on tradingview live data can use the tradingview charting library. It is free but you have to request access to the github repository.

Here is an example how easy it is to draw a shape:

var order = widget.chart().createOrderLine()
    .setText("Buy Line")
    .setLineLength(3) 
    .setLineStyle(0) 
    .setQuantity("221.235 USDT")
order.setPrice(7000);

This will then result in the following drawing (BTC/USDT chart):

There are plenty of example in the github repository so you wont be lost. BUT you have to create an own datafeed or at least set up a websocket connection to your desired data provider/marketplace.

I hope this helps everyone who is facing the same problem.

Tradigview Chart Widget can show only fixed list of predefined TradingView "studies":

that means it is impossible to create custom charts with it.
