ASX ITCH

Support for ASX Trade ITCH market data is provided by the AsxItchMarketDataFeedClient. This market data feed can be used by Spire to populate the security database for ASX listed securities, BBO quotes, time and sales, book quotes and order imbalances. In addition to real time market data, ASX Trade ITCH also provides a market data snapshot used for data recovery along with retransmission of dropped packets, both of which are fully supported.

Configuration

By default ASX ITCH is split into multiple feeds each handling a range of securities. Each feed is placed in its own directory and named asxitch_partition[N] with N = 1 representing the first feed. Each feed also has its own configuration file structured as follows:

Operations

The AsxItchMarketDataFeedClient contains the standard suite of scripts used to manage each individual feed.

The start.sh script is used to start either a single feed by specifying the feed's unique identifier partition[N] as a command line argument or used to start all feeds by passing all as a command line argument. Similarly the stop.sh script is used to stop a currently running feed. The list_feeds.sh will output all currently running feeds and the create_softlinks.sh script is used when first setting up the feeds, or when a new feed is added.

On startup a log file is created with the name srv_[YYYY][MM][DD]_[HH]_[MM]_[SS].log and is used to record dropped packets, any error messages or warnings, and if logging is enabled in the configuration file, a dump of every received message.
