Expect different market conditions
Extended sessions can have fewer participants, wider spreads and different order-handling rules than regular hours. News released after the main session may produce rapid moves while liquidity is limited. The price shown on one venue may differ from another, and an order valid during the main session may not automatically participate afterward. Understand which venue or product is being quoted before interpreting an after-hours price as an available execution.
Verify access for the exact instrument
Check the instrument's session schedule, time zone, holiday changes and permitted order types with the actual provider. Decide how you will handle an unfilled order or a price gap when the next session begins. FYLU has not published an executable extended-hours offering or instrument list. Its informational market pages and older reference schedules are not evidence that a particular asset can currently be traded through FYLU outside normal hours.
