# Delta Feed

* You receive and processes all deltas sent by Odds88. Revision/version numbers should not have any blank spots and every next delta should have revision incrementing by one.
* One delta can have multiple messages, thus multiple revisions - one revision for every message. Messages are processed in incremental order, to ensure correct state for events on your side. If some revisions are missed, events can have incorrect status and won’t be available for betting.
* Event start time is correct.
* Score, time, period, cards and penalties data is correct.
* Events and markets are available and displayed in accordance to **status** and **tradingStatus** properties.
* Odds are updated timely.
* Correct results for markets are received and processed on your side. Related tickets are settled accordingly. In case risk management from Odds88 is not used.
