Best prices including Virtual Bets - depth is controlled by ladderLevels 1 to 10 - Please note: Virtual prices are calculated for all ladder levels. Multiple field filters may be combined; a subscription message that contains data fields should look like the following: This is the ChangeMessage stream of data we send back to you once you subscribe to the market stream.

Most of the change based data RunnerChange is delta based - this means a few rules: This subscription type is used to receive order changes; the subscription message has one type of filter.

This optional filter already filters by your account; but additional data shaping is supported. Returns strategy positions OrderRunnerChange. This is the ChangeMessage stream of data we send back to you once you subscribe to the order stream.

An order cache is somewhat simpler as orders are sent in full on change and only matches need delta merging. Market subscriptions - are always in underlying exchange currency - GBP. Orders subscriptions - are provided in the currency of the account that the orders are placed in. Will receive a transient of the order to EC - Execution Complete as the order transits into that state allowing you to remove the order from your cache.

The example shows matched backs on two separate markets one of which has a size remaining of 0. This is an explicit heartbeat request in addition to server heartbeat interval which is automatic. This functionality should not normally be necessary unless you need to keep a firewall open. No - under normal circumstances the subscription level ChangeType. Use the HeartbeatMessage only if you need to keep a firewall open - as it will incur some performance penalty as a response will block your connection.

For these matched bets, you will receive on the Order Stream both a uo for the affected bet and the relevant updates to mb or ml reducing the matched volume at the original matched price and adding volume at the new reduced price.

See the avp in the uo record showing the new price of 9. The MarketDefinition of Line markets provide some additional fields that will be null for all other types,. For updates for Orders on Line markets received on the Order Stream be aware of how the following properties behave,. This is feature will be used in addition to the heartbeat mechanism which only gives an indication that the service is up but doesn't provide an indication of the latency of the data provided.

The status is sent per each subscription on heartbeats and change messages. This field will now be present in some cases on the Order object of the Order Stream to denote the reason that some or all of the order is lapsed.

It will be null if no portion of the order is lapsed or if the order lapsed for some reason other than those listed below. Logged in My account Sign out. A t tachments 8 Page History.

Common Authentication Errors Some common authentication errors that you should handle - these are defined on ErrorCodes enum these will all close your connection: The Order Changes and Market Changes are being produced by 2 independent systems so we can give no guarantee as to the order in which they will be sent.

Heartbeat ChangeMessages heartbeatMs is a guarantee of how often even with no changes you will receive a ChangeMessage; i. Coarse vs Fine Grain Subscriptions It is preferable to use coarse grain subscriptions subscribe to a super-set rather than fine grain specific market ids. If you find yourself frequently changing subscriptions you probably want to find a wider super-set to subscribe to.

Subscriptions with no matching markets We don't verify your subscription criteria as you could potentially subscribe to either a wild card which would include future markets or a future marketid which we do not have yet but would send on arrival. Correctly configuring field filters Correctly configuring field filters can help by: Reducing the size and time of initial images Reducing the rate of change as only changes matching your field filter are sent.

Currencies Market subscriptions - are always in underlying exchange currency - GBP. Unmatched Orders New subscriptions: Will receive an initial image with only E - Executable orders unmatched. Do I need to use HeartbeatMessage? Cost is identical as the two subscriptions above would evaluate in sequence and thus with the same average latency. Initial image is more costly to send than extra updates.

Limiting data with appropriate filters reduces initial image time Segmented data will always out perform non-segmented data: Powered by Atlassian Confluence 6.

General errors not sent with id linking to specific request as no request context. Failure code returned when an invalid input is provided could not deserialize the message.
