What it is — Rollover
Rollover is the daily process at ~5pm New York time (21:00/22:00 UTC) when open positions are extended to the next value date and swap (overnight interest) is applied — earned on some sides, paid on others, per the two currencies' rate differential.
It's also the daily infrastructure reset: liquidity thins for minutes, spreads widen briefly, and pending-order fills can slip. The weekly quirk: forex settles T+2, so Wednesday's rollover books triple swap to cover the weekend.
Why it matters — Rollover
- Hidden cost/revenue on every overnight trade — check before holding, especially on carry-unfriendly sides.
- Wednesday triple-swap can erase a thin trade's edge in one night.
- The 5pm window itself is treacherous: wider spreads + thin books = avoid placing market orders right on it.
Rollover on the clock
Rollover is the daily 5 p.m. New York settlement mark — about 21:00 or 22:00 UTC depending on daylight saving — when one trading day becomes the next, and swap (the interest differential on any position you keep open) is credited or charged to your account. Two mechanical quirks follow. Wednesday triples: the weekend’s interest settles early, so Wednesday’s rollover books three days at once — the standing example swings from $7 a day to $21 in one line on a carry position. Spreads spike: liquidity thins exactly then (the liquidity page’s daily floor), and a 1-pip EURUSD spread can widen several-fold for a few minutes — you can watch the sessions flip live on the session dashboard.
Trading around rollover without surprises
For most retail traders rollover is a non-event with three sharp edges. Stops and fills placed carelessly near 21:00 UTC can fill on a widened spread — the slippage page’s lesson in miniature, self-inflicted by timing. Positions opened and closed within the same day never pay swap at all — which is why day traders never think about it and swing traders must. And rate-differential changes (central-bank moves — see the calendar) rewrite swap schedules overnight, so last month’s “positive carry” pair can quietly flip negative. The boring defenses: check swap before holding anything overnight, avoid placing new orders in the rollover window, and treat Wednesday’s triple charge as part of the carry’s price, not a bug to discover later.
Frequently asked questions — Rollover
What time is rollover in my timezone?
5pm New York: 22:00 UTC in winter (23:00 in summer UTC-adjusted) — for UAE traders, 1:00–2:00 AM Gulf time. Check your platform's server clock (usually GMT+2/+3) in Market Watch.
What time is rollover in forex?
5 p.m. New York time — 21:00 or 22:00 UTC depending on daylight saving. It is when the trading day settles, swap is applied to open positions, and spreads briefly widen.
Why is swap charged three times on Wednesday?
The weekend's interest is settled at Wednesday's rollover: banks are closed Saturday and Sunday, so those two days book together with Wednesday's — one line, three days of swap.
Can I earn swap as a strategy?
Carry trading is a real, decades-old strategy — long the high-yielder against the low-yielder. It dies suddenly in risk-off crashes, so it's never a “free” income stream.
