Build with Ordien.
Use a common exchange contract for market tools, analytics and trading applications. The API is part of Ordien, with documented capabilities and clear access requirements.
One contract. Visible capabilities.
Inspect the operation, the exchange implementation and its current availability before you integrate. Shared response conventions keep common tasks familiar; documented extensions preserve meaningful venue differences.
Check support
See exchange evidence, implementation coverage and access requirements separately. A listed operation is not a promise of live execution.

How the API fits into Ordien
Markets presents exchange context in the product. Strategies provides a separate paper simulation. Operations works with organization-scoped records and provisional reporting. Sharing the Ordien identity does not move assets or extend permissions between these areas.
