What to Do When a Broker API Rejects an Order
Broker API order rejections are part of real-world trading software. This guide explains rejection categories, logging, user messages, retry rules and escalation so failures are handled safely.
Handling Partial Fills in Trading Software
Partial fills occur when an order is executed for only part of its requested quantity. Trading software must track filled and remaining quantities correctly so positions, exits, accounting and user-visible status remain consistent.
Preventing Duplicate Orders During Network Retries
Network failures can make an automated trading system uncertain about whether an order was actually accepted. Client order IDs, idempotency records and broker reconciliation can help systems retry safely without blindly creating duplicate orders.
