MarketData Request

Subscribing to Streaming Data

The T4 FIX API provides (optional) subscriptions to streaming market data for all markets available in order routing. Market data is made available asynchronously and concurrently to order routing flow. The market data subscriptions are active during a FIX Session. They are initiated by Market Data Request messages (Tag 35=V). A Market Data Request is a general request for streaming of market data quotes on specific securities. Under the T4 FIX API, securities are defined by the Exchange, Contracts within an exchange and Markets for a specific contract. Exchanges are identified by an unique Exchange ID in Tag 207 (SecurityExchange). Contracts are characterized by its Contract ID in Tag 55 (Symbol). Markets are identified by an unique Market ID by Tag 48 (SecurityID).

Any time during a FIX Session, market data subscriptions can be requested for a specific market by specifying a Subscription Request Type (Tag 263=1). During the FIX session, the streaming market data (for any specific security) can be also unsubscribed (Tag 263=2).

A successful Market Data Request (for subscription) returns one or more Market Data messages containing one or more Market Data Entries. Currently, The T4 FIX API provides market updates with the MarketData Snapshot message (Tag 35=W) and the MarketData Incremental Refresh message (Tag 35=X). Market Data Snapshots carry multiple blocks of quote data delineated by Market Data Entries. Each Market Data Entry is a bid, an offer, a trade, settlement price of a security, the trading session high price, low price, or trade volume, open interest and low and high price limits. Market Data Entries usually have a price and a quantity (size) at a book level (for securities with market depth). For example, in an order book environment, requesting just the top of book would result in two active Market Data Entries; one for the best bid and one for the best offer. For a full book, the bid and offer sides may each have several Market Data Entries corresponding to multiple book levels. Market Data Incremental Refresh messages provide depth updates in an incremental fashion and are only applied to specific book levels as opposed to all levels of the entire depth book.

Market Data requests that cannot be honored are notified via the MarketData Request Reject message.


Subscription Types

The following Subscription Request Types control attributes, initiation and termination of streaming market data:

Subscribe: A Snapshot + Updates subscription (Tag 263=1) causes the current state of the market to be sent, and any updates as they occur, until the client requests that the Snapshot + Updates be unsubscribed. All asynchronous market data updates are sent as MarketData Snapshots. This request initiates a continuous feed of streaming data.

UnSubscribe: Unsubscribing from currently streaming market data is specified with an "Unsubscribe" Subscription Request Type (Tag 263=2).

SnapShot: A Market Data Snapshot (Tag 263=0) causes the current state of the market to be sent. Currently, this subscription type is equivalent to Snapshot + Updates (Tag 263=1). Note that as the current data flow is driven by Market Data Snapshot messages, the complete view of a market may be rendered by a single Market Data Snapshot update. For a complete description of the market, the T4 FIX API also sends a Market Data Snapshot message associated with non-book entries (e.g. Trade Volume, Session high, Session low, etc.).

Subscribe Incremental: A Snapshot + Updates_Incremental subscription (Tag 263=7) causes the current state of the market to be sent, and any updates as they occur, until the client requests that the Snapshot + Updates_Incremental be unsubscribed. After an initial MarketData Snapshot, asynchronous market data updates are sent as MarketData Incremental Refreshes. This request initiates a continuous feed of streaming data.


Data Throughput and Buffering Levels

The T4 FIX API offers several levels of data throughput. The market data subscriber can control the number of quotes and the throughput rate (received by a client application). The T4 FIX API buffers streaming market data flow and disseminates quotes at the throughput level requested by the API client. Smart Buffering is recommended.

The following T4 buffering levels are available:

SlowTrade: Same as SlowSmart buffering plus every individual trade is received as well. It should be used sparingly due to high bandwidth and potentially large number of messages being received during busy market periods.

SmartTrade: Same as Smart buffering plus every individual trade is received as well. It should be used sparingly due to high bandwidth and potentially large number of messages being received during busy market.

SlowSmart: Slowed down version of Smart buffering for lower bandwidth usage. This produces depth updates about once per second per market if changes have occurred.

Smart: Smart buffering (Recommended), depth is sent out on different buffering intervals dependent on what has changed in the depth. Changes to the best bid, offer or last trade are sent out frequently, changes that are off the market are sent out less frequently.

FastSmart: Faster version of Smart buffering. It sends out changes to best bid or offer prices more frequently. Much higher bandwidth usage.

All: All depth updates, no buffering. It should be used sparingly due to high bandwidth and potentially large number of messages being received during busy market periods.

FastTrade: Same as FastSmart buffering plus every individual trade is received as well. It should be used sparingly due to high bandwidth and potentially large number of messages being received during busy market periods.

TradeOnly: Every individual trade is received, but nothing else - no depth, settlement, highlow, price limits etc.


Book Depth

The T4 FIX API Book Depth controls the number of book levels received for each update. Dependent on the specific security, up to a maximum of 10 book levels are available. The number of levels in the market data book is requested with MarketDepth (Tag 264). Higher number of levels will result in increased bandwidth requirements. If the best bid/offer is just needed for a quote board, a subscription to Level 1 is recommended. If a market is to show all depth lines, subscription to a Market Depth of 10 is required. Even if such security does not support 10 levels of market data, the T4 FIX API will provide the maximum number of levels that security currently supports.


Matching Market Data Messages against Market Data Requests

Market Data messages can be matched (by the FIX API client) through either the (unique) SecurityID (Tag 48) or by the Request ID (MDReqID - Tag 262) of the Market Data Request that initiated the streaming. SecurityID (Tag 48) is the default identification mechanism. To request identification by MDReqID, the market's SecurityDesc (Tag 107) must be set to 262. If the client requests to identify by MDReqID, the SecurityID will not be included in the market data messages.


Chart Data Requests

The T4 FIX API provides access to Chart (Time-and-Sales) Data primarily for the construction of historical graphs and charts. The data can be time-aggregated by day, hour, minute and second as well as by Tick, Time Price Opportunity (TPO) and Tick Change. The T4 FIX API optimizes its data transmissions by optionally compressing and encoding FIX API chart data responses.

FIX sessions involving chart data are established separately with FIX API chart data servers - as shown in System Access. Chart Data requests are only available if the FIX Session is initiated with a FIX Logon message containing the Enable Chart Data Requests attribute (Tag 372=V). Regardless of heartbeating, such FIX sessions are under a time-out interval of 60 seconds. That is, the FIX session automatically logs out if no Chart Data request is received within any 60 second time span.

Requests for Chart Data are performed with the Market Data Request message as governed by the SubscriptionRequestType field (Tag 263). Responses to Chart Data requests are provided with the MarketData Snapshot message (Tag 35=W). Currently, the following SubscriptionRequestTypes (Tag 263) are available for Chart Data:

TIME_AND_SALES_DATA_BATCH (Tag 263=4): Covers requests over multiple days and a user-defined Session time span. This is the recommended SubscriptionRequestType.

TIME_AND_SALES_CONTRACT (Tag 263=5): Covers requests over one single trade date for all markets of a contract. Total Volume Traded information is only provided.

Multiple day spans are defined with the fields TradeDateStart (Tag 3200) and TradeDateEnd (Tag 3201). A Session time-span can be specified with the fields SessionStartTime (Tag 3202) and SessionEndTime (Tag 3203). The (time) granularity of the returned responses can be controlled with the ChartType field (Tag 3204).

A Chart Data request can also control the compression/encoding of its corresponding response. The DataFormat (Tag 3205) of COMPRESSED_TAGS will return all Chart Data tags as compressed and Base-64 encoded Tag-Value pairs in the EncodedText field (Tag 355) of the MarketData Snapshot message. Uncompressed responses explicitly provide the Chart Data Tag-Value pairs as part of the MDEntries repeating group of the MarketData Snapshot message.
