Update clob_types.py

[codecadede]

Note

Refactors clob_types.py with Enum-based types, new Base/Limit/Market order args, Optional-typed query models, TickSize/options types, and removes redundant serialization helpers.

• Types & Enums
  • Replace old enumerate classes with Enum for OrderType and new AssetType.
  • Add TickSize Literal and option structs (CreateOrderOptions, PartialCreateOrderOptions).
• Order Models
  • Introduce BaseOrderArgs; split into OrderArgs (limit) and MarketOrderArgs (market) with order_type defaulting to FOK.
  • Consolidate common fields and clarify docstrings; add expiration to OrderArgs.
• API/Query Models
  • Add/clarify dataclasses (ApiCreds, RequestArgs, BookParams).
  • Update filter params (TradeParams, OpenOrderParams, DropNotificationParams, BalanceAllowanceParams) to use Optional types.
• Order Book Models
  • Simplify OrderSummary and OrderBookSummary; remove custom __dict__/json properties in favor of asdict/dumps.
• Misc
  • Add RoundConfig, enhance ContractConfig docs, and general type/documentation cleanup.

Bug: Removed property still referenced in hash generation

The json property was removed from OrderBookSummary but is still referenced in utilities.py at line 32 in generate_orderbook_summary_hash. The function attempts to access orderbook.json which no longer exists, causing an AttributeError at runtime when generating orderbook hashes.

Bug: Enum not JSON serializable in order submission

Changing from the old (incorrect) enumerate base to proper Enum breaks JSON serialization. The OrderType enum is passed directly to order_to_json in utilities.py and placed in a dictionary that gets JSON serialized by httpx. Python's standard json module cannot serialize Enum objects, causing a TypeError when posting orders. The enum value needs to be extracted using .value before serialization.

Bug: Enum string conversion produces incorrect query parameter

Changing AssetType from enumerate to Enum breaks query parameter generation in helpers.py line 153. The code calls params.asset_type.__str__() which returns "AssetType.COLLATERAL" instead of just "COLLATERAL". This produces malformed API query parameters. The enum value should be accessed using .value instead of .__str__() for proper serialization.
