the market is definitely closed over the weekends
This is not true there is no single market to close. brokers shut the price feed to retail traders down on the weekend. Oanda’s price feed runs 24/7 except when they are working on the servers. They do this on the week end. Spreads are very big but most of the time you can close a trade if you need to. On Sunday you can see price start to move around 1pm New York time. The weekend gaps that traders talk about are usually made during this pre-open activity. Its very choppy and spreads are still pretty high.
