Prop Firms That Allow Overnight Holding

Many prop firms — especially in the futures space — require traders to flatten before the daily close. That rules out swing strategies, multi-day trends, and any approach that relies on holding through the settlement window.

The firms below permit overnight holding on at least some of their programs. Rules still vary: some allow it only on funded (post-evaluation) accounts, some charge additional margin, and some cap position size across the close.

If your edge depends on holding through the close, this is a hard filter — start here and confirm the specific overnight-margin and product rules directly with each firm.
