Module trading 

Binance Spot WebSocket API client with SBE (Simple Binary Encoding) support.

This module provides a WebSocket API client for Binance Spot trading using the request/response pattern with SBE-encoded responses. It complements the HTTP client by offering lower-latency order submission via WebSocket.

Architecture

The client uses a two-tier architecture per the adapter design guidelines:

• Outer client (BinanceSpotWsTradingClient): Orchestrates connection lifecycle, maintains state for Python access, sends commands via channel.
• Inner handler (BinanceSpotWsTradingHandler): Runs in dedicated Tokio task, owns WebSocket connection, processes commands and responses.

Features

• Order placement, cancellation, and modification via WebSocket
• SBE-encoded responses for consistency with HTTP client
• Ed25519 and HMAC authentication (auto-detected)
• Request/response correlation by ID
• Inline user data stream (session.logon + userDataStream.subscribe)
