FAQs About Our Real Time Market Data API

How do you get your real time stock & options data?

SpiderRock connects to multiple and redundant data feed sources in large financial market datacenters. Some connections are direct to exchange venues for proprietary feeds. For consolidated feeds we connect to secondary suppliers who distribute feeds to institutional buyers.

Why are some real time market data quotes delivered on a 15 minutes delay?

Market data is typically supplied in real-time, delayed, and historical formats from exchanges through licensed distributors. For most market data, delayed data and historical data are not generally fee liable, although you may need to register your use with the exchange. As a result of this licensing structure, it is popular to distribute market prices delayed to users who don’t require it in real-time.

What is the latency on your live market data API?

The use of any API will increase the latency of market data. Normalizing or processing the feed is a trade-off between ease of access and speed. The latency impact on any feed is highly variable depending on locations and feed bandwidth at a given time. The typical latency for a SpiderRock API is around 1 ms or less.

How does SpiderRock normalize the market data?

We transform data into structures suited to common processing tasks. For example, we offer a version of an OPRA feed that includes the best and second-best prices and sizes in the marketplace and a bitmask of all participating exchanges. Transformed in this way, it is possible to process the full OPRA feed using a single thread of a single core on a current-generation machine.

All SpiderRock normalized feed products are disseminated in native ticker formats and include the ticker source information in each packet that allows seamless integration of data from multiple sources, even when native tickers collide. In addition, we offer normalized exchange product definition information to help you manage a diverse product environment.

What is the OPRA price feed?

The Options Price Reporting Authority (OPRA) is responsible for aggregating and disseminating price quotations for listed options contracts in the U.S. OPRA provides data feeds to financial firms, brokers, and traders, displaying the national best bid and offer for an options contract or series.
