API reference documentation improvements

Order type, side, time in force, and trading session are no longer repeated as enums in the API reference. They now follow the Trading Naming Dictionary, and the documentation has been updated accordingly.

Affected endpoints:

• POST /api/v1.0/accounts/{acc_id}/orders
• GET /api/v1.0/accounts/{acc_id}/acctradinginfo
• GET /api/v1.0/accounts/{acc_id}/funds

Trailing stop orders added

Added · Trading

Place and modify orders now support trailing stop market and limit orders, with new TRAILING_STOP and TRAILING_STOP_LIMIT order types. Adds a PositionOpenType enum controlling whether opening new positions is allowed; the Order response structure returns position_open_type accordingly.

Affected endpoints:

• PUT /api/v1.0/accounts/{acc_id}/orders/{order_id}
• GET /api/v1.0/accounts/{acc_id}/orders

Algo orders added

Added · Trading

Adds TWAP / TWAP_LIMIT / VWAP / VWAP_LIMIT / POV / POV_LIMIT / SLICER / SLICER_LIMIT / PEG / PEG_LIMIT / ICEBERG_LIMIT order types. The request body gains an algo_info parameter (an AlgoInfo structure with common start_time / end_time / pricing_strategy / layering fields and per-algo sub-structures TwapInfo / VwapInfo / PovInfo / SlicerInfo / PegInfo / IcebergInfo); order query responses return algo_info accordingly.

Affected endpoints:

• PUT /api/v1.0/accounts/{acc_id}/orders/{order_id}
