A market’s executable status belongs to the server feed, not the browser clock.
Open positions are automatically closed and pending orders cancelled at 5:00 p.m. New York time on Friday, the standard weekly FX market close. New orders are blocked until the market reopens Sunday at 5:00 p.m. New York time.
Synthetic training quotes run continuously and do not model exchange holiday calendars or promise executable real-market conditions. Weekend flattening follows the published weekly schedule even when training quotes are synthetic.
Production sessions, daylight-saving transitions, weekend closures, and holiday schedules must be configured from the licensed provider and disclosed per instrument.
Weekend positions are flattened using the last available quote at weekly close; stale data or a market gap can change the exit outcome. A stop or forced close cannot guarantee a price.
