Intrinio provides real-time stock and option prices via a two-way WebSocket connection.
$ dotnet add package IntrinioRealTimeClientSDK for working with Intrinio's realtime Multi-Exchange prices feed. Intrinio’s Multi-Exchange feed bridges the gap by merging real-time equity pricing from the IEX and MEMX exchanges. Get a comprehensive view with increased market volume and enjoy no exchange fees, no per-user requirements, no permissions or authorizations, and little to no paperwork.
Intrinio provides real-time stock prices via a two-way WebSocket connection. To get started, subscribe to a real-time data feed and follow the instructions below.
Documentation for our legacy realtime client
Go to Release, download the DLLs, reference it in your project. The DLLs contains dependencies necessary to the SDK.
For a sample .NET project see: intrinio-realtime-options-dotnet-sdk
static void Main(string[] _)
{
Client.Log("Starting sample app");
client = new Client(OnTrade, OnQuote);
timer = new Timer(TimerCallback, client, 10000, 10000);
client.Join(); //Load symbols from config.json
//client.Join(new string[] { "AAPL", "GOOG", "MSFT" }, false); //Specify symbols at runtime
Console.CancelKeyPress += new ConsoleCancelEventHandler(Cancel);
}
There are thousands of securities, each with their own feed of activity. We highly encourage you to make your trade and quote handlers has short as possible and follow a queue pattern so your app can handle the volume of activity.

Client client = new Client(OnTrade, OnQuote); - Creates a new instance of the Intrinio Real-Time client. The provided actions implement OnTrade and OnQuote, which handle what happens when the associated event happens.
onTrade: The Action accepting trades. This function will be invoked when a 'trade' has been received. The trade will be passed as an argument to the callback.onQuote: Optional. The Action accepting quotes. This function will be invoked when a 'quote' has been received. The quote will be passed as an argument to the callback. If 'onQuote' is not provided, the client will NOT request to receive quote updates from the server.client.Join(symbols, tradesOnly); - Joins the given channels. This can be called at any time. The client will automatically register joined channels and establish the proper subscriptions with the WebSocket connection. If no arguments are provided, this function joins channel(s) configured in config.json.
symbols - Optional. A string representing a single ticker symbol (e.g. "AAPL") or an array of ticker symbols (e.g. ["AAPL", "MSFT", "GOOG"]) to join. You can also use the special symbol, "lobby" to join the firehose channel and recieved updates for all ticker symbols. You must have a valid "firehose" subscription.tradesOnly - Optional (default: false). A boolean value indicating whether the server should return trade data only (as opposed to trade and quote data).client.Join(["AAPL", "MSFT", "GOOG"])
client.Join("GE", true)
client.Join("lobby") //must have a valid 'firehose' subscriptionclient.Leave(symbols) - Leaves the given channels.
symbols - Optional (default = all channels). A string representing a single ticker symbol (e.g. "AAPL") or an array of ticker symbols (e.g. ["AAPL", "MSFT", "GOOG"]) to leave. If not provided, all subscribed channels will be unsubscribed.client.Leave(["AAPL", "MSFT", "GOOG"])
client.Leave("GE")
client.Leave("lobby")
client.Leave()client.Stop() - Closes the WebSocket, stops the self-healing and heartbeat intervals. Call this to properly dispose of the client.
