Different interfaces, different authority
A market-data API and an order API do different jobs. Receiving a quote does not authorize an order or establish access to a brokerage account. Define the boundary between reference data, research, risk checks and execution. OptionAPI.com provides the reference and examples, not a live order-routing service.
Resolve the instrument before the instruction
An order proposal needs a verified contract identity, documented quantity unit and known lifecycle state. A ticker guessed by a model is not enough. Keep every proposed action traceable to the contract definition and data observations on which it relies, and reject unresolved records rather than improvising.
Treat a timeout as an unresolved event
A missing response does not prove an instruction was never received. An execution implementation needs explicit states, reconciliation and a documented retry policy using the provider’s supported features. Read-only examples on this site do not attempt order submission or imply exactly-once financial execution.
Keep controls independent of the strategy
Permissions, limits and stop procedures should not be editable through a strategy’s generated rationale. FINRA’s algorithmic-control guidance provides a useful reference for testing and monitoring; applicability and compliance require appropriate professional review. Our guide develops an engineering evaluation plan, not a certification.
