Market data / Pricing data
-Market data is also a synonym for pricing data.
In finance, Market Data refers to; quote and trade related data disseminated from equity, fixed-income, derivatives, currency, or other exchanges. Market data may refer generically to data both directly originating from an exchange and derived from these underlying instruments (e.g. indices). While market data generally refers to realtime or delayed quotations, the domain can broadly exclude static or reference data relating to these instruments (e.g. CUSIP, which exchange; a security trades on, end-of-day pricing, etc.). This data is generally captured and furnished to users via large scale enterprise computing systems, in either a request-response or streaming manner.
A
typical equity market data message or business object furnished from NYSE, TSX,
or NASDAQ might appear something like this;
| Ticker Symbol | IBM |
| Bid | 89.02 |
| Ask | 89.08 |
| Bid size | 300 |
| Ask size | 1000 |
| Last sale | 86.06 |
| Last size | 200 |
| Quote time | 14:32:45 |
| Trade time | 14:32:44 |
| Exchange | NYSE |
| Volume | 7808 |
In actuality, the above example is an aggregation of different sources of data, as quote data (bid, ask, bid size, ask size) and trade data (last sale, last size, volume) are often generated over different data feeds.
