What Is a Rollover
Rollover is the moment at midnight on the platform's clock when the trading day ends and every open trade is carried into the next one. This paper shows you what it does to one real trade — the same row a minute before and a minute after — why Wednesday's rollover books three nights, and whose midnight it happens at.
Every platform has a clock, and at midnight on that clock the trading day ends. Rollover is what happens to an open trade at that moment: it is carried, rolled, into the next day. Nothing is closed and nothing is reopened. The trade keeps its open price, its size and its stops. The one thing written into it is the overnight charge — the swap, the interest for holding the pair one more night — and on a Wednesday that charge is written three times. The row for one lot — 100,000 euros — bought on Monday 31 August 2026 carried two nights of swap into Wednesday evening and five nights out of it.
What changes and what does not
Here is the real row a minute before and a minute after a Wednesday midnight. At 23:59 on 2 September 2026 it read one lot bought at 1.15811, valued at the day's last price, 1.15881 — a pip is the fourth decimal place, so seven pips and $70 up — with $14 of swap from Monday and Tuesday nights. At 00:01 on Thursday the open price, the size and the stops were exactly what they had been. The price had moved a little, as prices do at every minute. And the swap column had gone from −14 to −35: three nights, $21, written at once. Nothing was done to the trade except that.
