Creating a Dashboard displaying Cryptocurrency Data using Node-RED
We will use the STS Binance node to get access to a Cryptocurrency API. The node can be downloaded for Node-RED. The following flow will get us the exchange price for Etherium:

We start with setting an Inject Node to an empty string and its topic to ETHUSDT (exchange chart) and connecting it to getPrice Node - a Debug Node will give us the result in form of a string - e.g. 294.50000000.
Let’s continue the example shown above but extend it to get all market info. For that we’ll need the getAllPrices Node:

You’ll get back a JSON object:

Working with the Node-RED Dashboard
Adding Text Outputs
We now create a flow that triggers a getBookTicker Node to get both the Bid and Ask Price for Bitcoin:

The result of the Ticker Node is a JSON Object:
{'symbol':'BTCUSDT','bidPrice':'7076.23000000','bidQty':'0.12495100','askPrice':'7079.97000000','askQty':'0.70947800'}
We can feed this into two Text Nodes to display both the {{msg.payload.bidPrice}} and {{msg.payload.askPrice}} and embedd them into our Node-RED Dashboard.
Adding a Graph
Lets add a graph UI node and take the output from the getBookTicker Node and prepared it so that the graph node can display both the ask price and the bid price on the same graph. We add two Change Nodes and name them isolateBidPrice and isolateAskPrice. Change nodes allow you to take input messages and change the output based on a set of rules. To be able to use the chart properly, we need to deliver a msg.payload with a chartable value, and a msg.topic set to the name of the chartable value.

Now that we have two messages arriving at the chart node, it will use the msg.topic field to distinguish between the two and will apply a series colour to the data series that arrive, in our case dark blue to series 1 (bidPrice)and light blue to series 2 (askPrice).
The last thing we do is change the inject node to repeat every 10 seconds so we don’t have to keep clicking on it. Deploy and take a look at the dashboard which should look like the screenshot on top of this article.
