How to import Quandl data into TradingViewQuandl is a data library with all sorts of useful macroeconomic data. Unfortunately a lot of it you have to pay for, but there are also many data series you can access for free, including the "Blockchain" library with lots of useful data such as Bitcoin transaction fees.
To access Quandl data, go to quandl.com. In the left-hand column, check the "Free" box to ensure your search results include only free data sets. Then type what you're looking for in the text box (e.g. "US wages" or "Bitcoin transaction cost"). Click the name of a data set in the search results. You should now see a chart. On the right hand side of the chart, click the "TradingView" button to import to TradingView.
