Spread behaviour
Spreads widen outside US session
S&P500 trades Monday 22:00 UTC to Friday 21:00 UTC. There is a daily break from 21:00 UTC to 22:00 UTC. Trading is not available on weekends.
At Afterprime, S&P500 is available as a CFD, meaning you can go long or short within these hours without owning the underlying asset. All times shown follow the underlying exchange and adjust automatically for daylight saving changes in the US and Europe.
S&P500 typically sees its highest liquidity and tightest spreads during US cash session open + NY overlap (12:00 UTC–16:00 UTC). Volume spikes at the US open (9:30 AM ET) and in the final hour of trade.
Lower-volume periods, particularly pre-market hours, may see wider spreads and thinner order books. For traders on momentum and intraday strategies, timing entries around the US cash session open + NY overlap open tends to offer the most favourable conditions.
S&P500 has a short daily maintenance break but is otherwise available throughout the entire trading week. Orders placed while the market is closed are queued and executed at the next available open price.
If you have a pending position when the market closes, it will be held overnight and a swap rate will apply. For S&P500, the current swap rates are -1.853 points long and 0.189 points short, with a triple swap applied on Friday.
