The 1DTE Overnight Hold: When Carrying Risk Overnight Makes Sense
Most scalps are flat by the close. Carrying a 1DTE overnight is a different bet — you trade the theta cliff for gap risk, and that trade only pays with a real reason.
A 1DTE option — expiring tomorrow — can be held overnight, unlike a 0DTE that must be dealt with by the close. That overnight hold swaps one risk for another, and it's only worth it with a specific thesis.
What you're trading
By holding overnight you avoid the worst of today's theta cliff (a 1DTE has more time value than a 0DTE), and you position for a move that plays out at the next open. But you take on overnight gap risk — the market can gap against you while you can't react — plus calendar decay (worse over a weekend), and the option still faces its own theta cliff tomorrow. You're betting the overnight move outweighs those costs.
When it makes sense
The overnight hold is justified mainly by a strong directional thesis into a known catalyst — e.g., positioning ahead of a morning economic print or a continuation you expect to gap in your favor — where the potential move is large relative to the gap risk. It's a deliberate, sized bet, not a “I'll just give it more time” default.
Carrying a 1DTE overnight is a position trade wearing a scalper's clothes. Do it for a thesis and a catalyst, never to avoid taking a loss.
When it doesn't
Never hold overnight to avoid booking a loser — that's the gap risk working against a position you already doubt. Never hold into a weekend without accounting for the extra decay. And size it as the higher-risk trade it is. If you do carry it, have a morning exit plan ready for the open. With NoVo, staying flat by the close or carrying a 1DTE overnight is your call either way — an intentional overnight hold is a choice you make with eyes open, not a fallback.
