Handling Events

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 has short as possible and follow a queue pattern so your app can handle the volume of activity. Note that quotes (ask and bid updates) comprise ~90% of the volume of the entire feed. Be cautious when deciding to receive ask/bid quote updates.

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.

Overview

The Intrinio Realtime Client will handle authorization as well as establishment and management of all necessary WebSocket connections. All you need to get started is your API key. The first thing that you'll do is create a new Client object. After a Client object has been created, you will immediately register a series of callbacks, using the setOnX methods (e.g. setOnTrade). These callback methods tell the client what types of subscriptions you will be setting up. You must register callbacks in order to receive data. And you will only receive data for the types of callbacks that you have registered (i.e. you will only receive trade updates if you register an OnTrade callback). After registering your desired callbacks, you may subscribe to receive feed updates from the server. You may subscribe to a static list of symbols (a mixed list of option contracts and/or option chains). Or, you may subscribe, dynamically, to option contracts, option chains, or a mixed list thereof. It is also possible to subscribe to the entire universe of option contracts by calling JoinLobby. The volume of data provided by the lobby (Firehose) exceeds 100Mbps and requires higher hardware requirements. Do not subscribe to lobby and individual symbols/chains/contracts at the same time - either join lobby by itself, or a list of symbols/chains/contracts. After subscribing your starting list of symbols, you will call the start method. The client will immediately attempt to authorize your API key (provided in the config.json file). If authoriztion is successful, the necessary connection(s) will be opened. If you are using the non-firehose feed, you may update your subscriptions on the fly, using the join and leave methods. The WebSocket client is designed for near-indefinite operation. It will automatically reconnect if a connection drops/fails and when then servers turn on every morning. If you wish to perform a graceful shutdown of the application, please call the stop method. Realtime vs delayed is automatically handled by your account authorization. If you wish to force delayed mode and have realtime access, you may use the delayed parameter in your configuration.

Equities Methods

Client client = new Client(optionsTradeHandler, optionsQuoteHandler) - Creates an Intrinio Real-Time client. The provided handlers implement OnTrade and OnQuote, which handle what happens when the associated event happens.

• Parameter optionsTradeHandler: The handler for trade events. This function will be invoked when a 'trade' has been received. The trade will be passed as an argument to the callback.
• Parameter optionsQuoteHandler: Optional. The handler for quote events. 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.

• 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.join("lobby") //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.leave("lobby")
client.leave()

---

client.stop() - Closes the WebSocket, stops the self-healing and heartbeat intervals. Call this to properly dispose of the client.

Equities Configuration

config.json

{
	"apiKey": "",
	"provider": "REALTIME", //or DELAYED_SIP or NASDAQ_BASIC or MANUAL
	"symbols": [ "AAPL", "MSFT", "GOOG" ], //This is a list of individual tickers to subscribe to, or "lobby" to subscribe to all at once (firehose).
	"tradesOnly": true, //This indicates whether you only want trade events (true) or you want trade, ask, and bid events (false).
	"numThreads": 4 //The number of threads to use for processing events.
}

Options Methods

Client client = new Client(Config config) - Creates an Intrinio Real-Time client.

• Parameter config: Optional - The configuration to be used by the client. If this value is not provided, config.json will be picked up (from the project root) and used.

---

client.setOnTrade(OnTrade onTrade) throws Exception - Registers a callback that is invoked for every trade update. If no onTrade callback is registered with this method, you will not receive trade updates from the server.

• Parameter onTrade: The handler for trade events.
• Throws Exception: If the start method has already been called. Or if OnTrade has already been set.

client.setOnQuote(OnQuote onQuote) throws Exception - Registers a callback that is invoked for every quote update. If no onQuote callback is registered with this method, you will not receive quote (ask, bid) updates from the server.

• Parameter onQuote: The handler for quote events.
• Throws Exception: If the start method has already been called. Or if OnQuote has already been set.

client.setOnRefresh(OnRefresh onRefresh) throws Exception - Registers a callback that is invoked for refresh update. If no onRefresh callback is registered with this method, you will not receive open interest, high, low, open, close data from the server.

• Parameter onRefresh: The handler for refresh events.
• Throws Exception: If the start method has already been called. Or if OnRefresh has already been set.

client.setOnUnusualActivity(OnUnusualActivity onUnusualActivity) throws Exception - Registers a callback that is invoked for every unusual trade. If no onUnusualActivity callback is registered with this method, you will not receive unusual trade updates from the server.

• Parameter onUnusualActivity: The handler for unusual trade events.
• Throws Exception: If the start method has already been called. Or if OnUnusualActivity has already been set.

---

client.start() - Starts the Intrinio Realtime WebSocket Client. This method will immediately attempt to authorize the API key (provided in config). After successful authorization, all of the data processing threads will be started, and the websocket connections will be opened. If a subscription has already been created with one of the join methods, data will begin to flow.

---

client.join() - Joins channel(s) configured in config.json. client.join(String channel) - Joins the provided channel. E.g. "AAPL" or "GOOG__210917C01040000" client.join(String[] channels) - Joins the provided channels. E.g. [ "AAPL", "MSFT__210917C00180000", "GOOG__210917C01040000" ] client.joinLobby() - Joins the 'lobby' (aka. firehose) channel. The provider must be set to OPRA_FIREHOSE for this to work. This requires special account permissions.

---

client.leave() - Leaves all joined channels/subscriptions, including lobby. client.leave(String channel) - Leaves the specified channel. E.g. "AAPL" or "GOOG__210917C01040000" client.leave(String[] channels) - Leaves the specified channels. E.g. [ "AAPL", "MSFT__210917C00180000", "GOOG__210917C01040000" ] client.leaveLobby() Leaves the lobby channel

---

client.stop(); - Stops the Intrinio Realtime WebSocket Client. This method will leave all joined channels, stop all threads, and gracefully close the websocket connection(s).
