IntrinioRealTimeClient 11.0.1

intrinio-realtime-dotnet-sdk

SDK for working with Intrinio's realtime OPRA, IEX, delayed SIP, or NASDAQ Basic prices feeds. Get a comprehensive view with increased market volume and enjoy minimized exchange and per user fees.

Intrinio provides real-time stock and option prices via a two-way WebSocket connection. To get started, subscribe to a real-time equity feed, or subscribe to a real-time options feed and follow the instructions below.

Requirements

• .NET 8+

Docker

Add your API key to the config.json file in SampleApp as well as select the appropriate provider, comment the appropriate line in Program.cs, then

docker compose build
docker compose run example

Installation

Go to Release, download the DLLs, reference it in your project. The DLLs contains dependencies necessary to the SDK.

Sample Project

For a sample .NET project see: intrinio-realtime-dotnet-sdk Be sure to update config.json

Features

Equities

• Receive streaming, real-time pricing (trades, NBBO bid, ask)
• Subscribe to updates from individual securities, individual contracts, or
• Subscribe to updates for all securities (Lobby/Firehose mode)

Options

• Receive streaming, real-time option price updates:
  • every trade
  • conflated bid and ask
  • open interest, open, close, high, low
  • unusual activity(block trades, sweeps, whale trades, unusual sweeps)
• Subscribe to updates from individual options contracts (or option chains)
• Subscribe to updates for the entire universe of option contracts (~1.5M option contracts)

Example Usage

static async Task Main(string[] _)
{
	Client.Log("Starting sample app");
	var client = new EquitiesWebSocketClient(OnTrade, OnQuote);
    //var client = new OptionsWebSocketClient(OnTrade, OnQuote, OnRefresh, OnUnusualActivity);
    await client.Start();
	timer = new Timer(TimerCallback, client, 10000, 10000);
	await client.Join(); //Load symbols from config.json
	//client.Join(new string[] { "AAPL", "GOOG", "MSFT" }, false); //Specify symbols at runtime
    //client.JoinLobby(true); //Join the lobby instead (don't subscribe to anything else) to get everything.
	Console.CancelKeyPress += new ConsoleCancelEventHandler(Cancel);
}

static void Cancel(object sender, ConsoleCancelEventArgs args)
{
    Log("Stopping sample app");
    timer.Dispose();
    client.Stop();
    Environment.Exit(0);
}

Handling Quotes

There are thousands of securities and millions of options contracts, each with their own feed of activity. We highly encourage you to make your trade and quote handlers as short as possible and follow a queue pattern so your app can handle the volume of activity. Please note that quotes comprise 99% of the volume of the feed.

Client Statistics and Performance

The client is able to report back various statistics about its performance, including the quantity of various events and if and how much it is falling behind. The client has two internal buffers - a main buffer and an overflow buffer. The main buffer will spill into the overflow buffer when the main buffer is full, but if the overflow buffer fills, then messages start to drop until it catches up. The statistics allow you to see how full both buffers are, as well as how many have spilled into overflow, and how many were dropped altogether. If your client is dropping messages, you can try to increase buffer size, but the main problem is most likely that you need more processing power (more hardware cores, and more threads configured in your client config). Please see below for recommended hardware requirements.

API Keys

You will receive your Intrinio API Key after creating an account. You will need a subscription to a realtime data feed as well.

Methods

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.

• Parameter 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.
• Parameter 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.Start(); - Initializes and connects the client.

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.

• Parameter 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.
• Parameter 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.JoinLobby() //must have a valid 'firehose' subscription

client.Leave(symbols) - Leaves the given channels.

• Parameter 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.LeaveLobby()
client.Leave()

client.Stop() - Closes the WebSocket, stops the self-healing. Call this to properly dispose of the client.

Configuration

config.json

config.json The application will look for the config file if you don't pass in a config object.

{
  "Config": {
    "ApiKey": "API_KEY_HERE",
    "NumThreads": 8,
    //"Provider": "OPRA",
    "Provider": "REALTIME",
    //"Provider": "DELAYED_SIP",
    //"Provider": "NASDAQ_BASIC",
    //"Provider": "MANUAL",
    //"IPAddress": "1.2.3.4",
    "BufferSize": 4096,
    "OverflowBufferSize": 8192,
    "Symbols": [ "AAPL", "MSFT", "TSLA" ]
    //"Symbols": [ "lobby" ]
  },
  "Serilog": {
    "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning"
      }
    },
    "WriteTo": [
      { "Name": "Console" }
    ]
  }
}

To create a config object to pass in instead of the file, do the following. Don't forget to also set up sirilog configuration as well:

Log.Logger = new LoggerConfiguration().WriteTo.Console(restrictedToMinimumLevel: Serilog.Events.LogEventLevel.Information).CreateLogger();
Config.Config config = new Config.Config();
config.Provider = Provider.REALTIME;
config.ApiKey = "";
config.Symbols = new[] { "AAPL", "MSFT" };
config.NumThreads = 2;
config.BufferSize = 2048;
config.OverflowBufferSize = 4096;
client = new Client(onTrade, onQuote, config);
client.Start();

Example Replay Client Usage

static void Main(string[] _)
{
	Client.Log("Starting sample app");
	//You can also simulate a trading day by replaying a particular day's data. You can do this with the actual time between events, or without.
	DateTime yesterday = DateTime.Today - TimeSpan.FromDays(1);
	replayClient = new ReplayClient(onTrade, onQuote, yesterday, true, true, false, String.Empty); //A client to replay a previous day's data
	timer = new Timer(ReplayTimerCallback, replayClient, 10000, 10000);
	replayClient.Join(); //Load symbols from your config or config.json
	//client.Join(new string[] { "AAPL", "GOOG", "MSFT" }, false); //Specify symbols at runtime
	Console.CancelKeyPress += new ConsoleCancelEventHandler(Cancel);
}

Example Candlestick Client Usage

static void Main(string[] _)
{
	Client.Log("Starting sample app");
	Action<Trade> onTrade = OnTrade;
	Action<Quote> onQuote = OnQuote;
	
	//Subscribe the candlestick client to trade and/or quote events as well.  It's important any method subscribed this way handles exceptions so as to not cause issues for other subscribers!
	_useTradeCandleSticks = true;
	_useQuoteCandleSticks = true;
	_candleStickClient = new CandleStickClient(OnTradeCandleStick, OnQuoteCandleStick, IntervalType.OneMinute, false, null, null, 0, false);
	onTrade += _candleStickClient.OnTrade;
	onQuote += _candleStickClient.OnQuote;
	_candleStickClient.Start();
	
	client = new Client(onTrade, onQuote);
	timer = new Timer(TimerCallback, client, 10000, 10000);
	client.Join(); //Load symbols from your config or config.json
	//client.Join(new string[] { "AAPL", "GOOG", "MSFT" }, false); //Specify symbols at runtime
			
	Console.CancelKeyPress += new ConsoleCancelEventHandler(Cancel);
