Multi-leg A-share limit BUY via place_limit_order_batch when MCP supports it; otherwise fall back to sequential place_limit_order per leg. Each symbol must be canonical or resolved via stock-symbol-resolve; account_id locked per signal-trader multi-account rules.
Single-symbol A-share limit BUY via place_limit_order when user already has price/amount and locked account_id; requires canonical symbol or prior stock-symbol-resolve. Not for full signal-trader pipeline.
Cancel one open order via cancel_order for a locked account_id. Use when user gives order_id or points to a single resting order to cancel.
Cancel multiple open orders via cancel_orders_batch for a locked account_id; fallback to sequential cancel_order if batch tool unavailable.
