Library reference

The reference hierarchy mirrors the library interface. Choose the layer that matches your intent before choosing a namespace.

Layer	Mental model	Namespaces	Methods
Operations	One faithful typed IG call.	16	51
Workflows	A multi-operation journey composed from operations.	4	8
Types and exceptions	Objects constructed, returned, streamed, or raised by those two layers.	4 categories	-

Every method documents its parameters, sync and async examples, recursive response shape, response example, limitations, and exceptions.

• Parameter and response tables use public Python field names.
• Nested request fields include Pydantic defaults and declared constraints.
• ValidationError is pydantic.ValidationError; all other named failures are exported by ig_trading_lib.
• Mutation workflows retain DealConfirmationError.deal_reference; reconcile it instead of replaying the mutation.
