Seed CX provides market data for two distinct environments: Production and Certification.
The Production environment exists for live trading and order execution. It is recommended that applications conduct trial runs in the certification environment before executing live trades and consuming live market data.
The Seed CX Production environment is hosted in the Equinix NY4 data center located in Secaucus, NJ.
Seed CX’s production trading hours are 6:00 PM to 4:00 PM Central Time Sunday-Friday. The market becomes available at 5:55 PM Central Time Sunday-Friday. All outstanding orders will be canceled at the end of the trading day. New orders submitted after the end of the trading day will get rejected.
Seed CX has a Certification Environment which offers full exchange functionality using test funds. All funds are for testing purposes only.
The certification environment is available for applications to prove out and certify their readiness to work with Seed CX systems. This includes mock trading via FIX protocol as well as consumption of binary market data.
New instruments and features are first previewed in the certification environment before being released to the production environment.
