What Is the Daily Open

The daily open is the first price after the platform's midnight, the open of the day's first candle, and the day is read as distances from it: how far above, how far below, where it closed, and the percentage change. This paper shows you one day of the euro hour by hour against its open, the clock that decides when the day begins, the open as a line on the fifteen-minute chart, the day on one card with its change, and the Market Watch column that shows every symbol against its own open on your platform.

One day against its open

The daily open is the first price of the day: the open of the first candle after the platform's midnight. The euro against the dollar opened 10 October 2025 at 1.15531. The morning hours held within a few pips of that line — a pip being the fourth decimal place, the smallest step most people count in — and never went more than 6 below it. At 18:00 one hour rose to 1.16308, 78 pips above it, and the day closed at 1.16175, 64 above. Every hour of the day has one number against the open: how far above or below it is.

The platform's midnight

The picture is a clock at midnight. The daily candle closes and a new one opens at 00:00 on the platform's clock, which runs on the broker's time zone — for most brokers two or three hours ahead of London, so that the trading week fits into five daily candles. The daily open is the price at that stroke. It is not the price at your own midnight, and the same day has a different open on a platform whose clock is set differently.
