 ## Market Data types
 
-When requesting data from the FIX endpoint, the client should send a [MarketDataRequest](https://www.onixs.biz/fix-dictionary/4.4/msgType_V_86.html) (V) message. Three stream types will be available through this endpoint: trade and orderbook level 1 & 2. The type of data being requested should be indicated in the [MDEntryType](https://www.onixs.biz/fix-dictionary/4.4/tagNum_269.html) (269) field in line with the FIX documentation, with the addition of setting the [MarketDepth](https://www.onixs.biz/fix-dictionary/4.4/tagNum_264.html) (264) field to '1' for level 1 orderbook Data.

+A request for bid or offer data will be interpreted as a request for full orderbook data, we do not currently support providing only one side of the book.

 In order to distinguish between level 1 & 2 orderbook data, we mark each level 1 message by writing "TOB" into the 'text' field.
