DataFeed Delivery Mechanisms

QuoteMedia DataFeed provides a highly flexible data delivery framework to best suit the needs of the client. Market data is securely delivered via multiple discrete channels, with each channel being individually selectable and configurable so that clients can choose individual markets or exchanges, and the specific data points they wish to receive. This is ideal for those wishing to maximize client side efficiency and minimize bandwidth costs. Each channel can be configured as follows, depending on client needs.

1. TCP or UDP Clients can choose TCP (Transmission Control Protocol) connections, or UDP (User Datagram Protocol) messaging. The data can be streamed over dedicated lines or via the Internet.
2. Data Compression Clients can choose to receive compressed or uncompressed data. Compression can reduce bandwidth requirements by a factor of up to 6:1 during peak loads. QuoteMedia's DataFeed uses proprietary compression systems which decompress via standard ZLIB (gzip/deflate) decompression algorithms, thus allowing for easy client side decompression.
3. String Readable Data Format String Readable data facilitates fast client implementation. String readable data reduces client time-to-market by simplifying implementation, testing, and maintenance. QuoteMedia also supports MDDL (Market Data Definition Language), XML, and Binary data formats, always delivering the highest levels of performance.
4. Tick-by-Tick or Moderated Data Clients can elect to receive a complete feed for a given exchange, which includes every tick. Alternatively, clients can receive moderated feeds with aggregated updates. QuoteMedia’s proprietary aggregation algorithms can lower bandwidth expenses, reduce data volumes, and improve system efficiency for clients who do not require a complete tick-by-tick feed.
5. Real-Time or Delayed Data QuoteMedia’s DataFeed provides data in real-time or delayed. If delayed data is desired, pre-delayed data channels can be used to ensure proper compliance with Exchange licensing requirements.
6. Client-Side Software QuoteMedia can also provide optional client side tools and applications for data decompression, client-side data delaying, and multi-point relaying of data.
