System and method for communicating with an electronic exchange in an electronic trading environment
View Patent ↗System and methods for a connection proxy server are described. According to an example method described herein, a connection proxy server stores subscription, product tables as well as other downloads that are provided to a client terminal during initialization stage as well as later during a trading session. Upon detecting that a connection between the client terminal and a gateway is lost, the connection proxy maintains a communication session created for the client terminal at the gateway and receives data intended for the client terminal. If the connection is re-established between the client terminal and the gateway during a predetermined period of time, the connection proxy provides the stored data to the client terminal thus avoiding a surge in processing resources at the gateway due to the necessary downloads.
1. A system for an improved communication in an electronic trading environment, the system comprising:
a connection proxy,
wherein the connection proxy is adapted to receive initial download data, wherein the initial download data enables a client terminal to connect to an electronic exchange through an intermediary device, wherein the client terminal communicates with the electronic exchange using a communication session established for the client terminal at the intermediary device,
wherein the connection proxy is adapted to detect that a network communication link between the client terminal and the intermediary device has been terminated,
wherein the connection proxy is adapted to provide a signal to the intermediary device to maintain the communication session at the intermediary device for a predetermined period of time in response to detecting that the network communication link has been terminated,
wherein the connection proxy is adapted to receive market data related to a tradeable object during the predetermined period of time,
wherein the connection proxy is adapted to provide the initial download data and the market data related to the tradeable object to the client terminal if the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time, and
wherein the connection proxy is adapted to terminate the signal being provided if the network communication link between the client terminal and the intermediary device is not restored during the predetermined period of time.
2. The system of claim 1 , wherein the initial download data comprises initialization data.
3. The system of claim 1 , wherein the initial download data comprises subscription data.
4. The system of claim 1 , wherein the initial download data comprises data related to at least one tradeable object being traded at the electronic exchange.
5. The system of claim 1 ,
wherein the connection proxy is adapted to update the initial download data during a trading day.
6. The system of claim 1 ,
wherein the connection proxy is adapted to receive trade order data during the predetermined period of time, and
wherein the connection proxy is adapted to send the trade order data to the client terminal upon detecting that the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time.
7. The system of claim 6 , wherein the trade order data comprises fill order data.
8. The system of claim 6 , wherein the trade order data comprises order confirmation data.
9. The system of claim 1 ,
wherein the connection proxy is adapted to store the initial download data.
10. The system of claim 1 , wherein the tradeable object was subscribed to by the client terminal prior to detecting that the network communication link has been terminated.
11. The system of claim 1 , wherein, to provide a signal to the intermediary device, the connection proxy is adapted to:
generate a heartbeat message on behalf of the client terminal; and
provide the heartbeat message to the intermediary device at predefined time intervals during the predetermined period of time.
12. The system of claim 11 , wherein the connection proxy is adapted to provide a signal to terminate the communication session at the intermediary device.
13. The system of claim 1 , wherein the connection proxy is located at the intermediary device.
14. The system of claim 1 , wherein the connection proxy is in communication with the intermediary device.
15. The system of claim 1 ,
wherein the connection proxy is adapted to detect that the network communication link has been restored during the predetermined period of time.
16. The system of claim 1 ,
wherein the connection proxy is adapted to detect that the network communication link has not been restored during the predetermined period of time.
17. The system of claim 1 , wherein the intermediary device comprises a gateway.
