integraion points and format about parity HOT 1 CLOSED

Hi @SolutionJet! Here are some answers:

1. You can enter orders to the trading system using either the POE protocol or the FIX protocol. Both are TCP-based network protocols, and FIX is an industry standard with many free and commercial implementations.

   The terminal client and stock ticker are simple examples on how to interact with the trading system. The order entry and market data protocols themselves are implemented in the networking protocols library.

2. The trading system provides two distinct data feeds: market data and market reporting. The market data protocol contains only anonymous information and is intended for all market participants. In contrast, the market reporting protocol contains identifying information (who entered an order, who bought what, and who sold what) and is intended for post-trade processing systems and market surveillance systems.

   Both data feeds are based on a protocol called NASDAQ MoldUDP64 1.00, and that protocol defines the request format. There are also multiple implementations of this protocol; the implementation used by Parity is called Nassau.

3. As FIX is an industry standard, integrating to an exchange using FIX is usually much easier and faster than using the exchange's native order entry protocol. The downside is that FIX has usually higher latency than native order entry protocols, which are usually based on simple and efficient binary encoding.

You might find Genesis useful as an example of how the different parts fit together. Also, thank you for the reminder, I'll add an architecture diagram. Finally, please consider joining the Parity chat.
