V5 Core Traits

Architecture

CoreConnector<C>           - universal methods (Identity + MarketData + Trading + Account + Positions)
     │
     └── BinanceConnector  - core + all Binance-specific directly
     └── KuCoinConnector   - core + all KuCoin-specific directly

Principles

1. Core traits are minimal — only what 100% of exchanges support
2. No UnsupportedOperation in core — all core methods work everywhere
3. Extensions in exchange connectors — directly as struct methods

Core traits

Trait	Methods	Description
ExchangeIdentity	5	Basic identification
MarketData	5	Public data (price, orderbook, klines, ticker, ping)
Trading	5	Trading (place_order, cancel_order, get_order, get_open_orders, get_order_history)
Account	3	Account (balance, account_info, fees)
Positions	3	Futures (positions, funding_rate, modify_position)

Optional operation traits (part of CoreConnector)

• CancelAll - native cancel-all endpoint
• AmendOrder - native amend/modify order
• BatchOrders - native batch placement/cancellation
• AccountTransfers - internal account transfers
• CustodialFunds - deposits and withdrawals
• SubAccounts - sub-account management
• FundingHistory - historical funding payments
• AccountLedger - full account ledger
• Authenticated - credential-aware connectors
