What Is the Weekly Open

The weekly open is the first price of the week, the open of Monday's first candle, and the week is read as distances from it: how far above, how far below, where it closed. This paper shows you one week of the euro drawn hour by hour against its open, the idea as a starting line, the open as a line on the four-hour chart, the week as five daily closes measured from it, and how to pin the number to a corner of the chart on your platform.

One week against its open

The weekly open is the first price of the week: the open of Monday's first candle. The euro against the dollar opened the week of 15 September 2025 at 1.1727. It dipped 11 pips under that line on Monday morning — a pip being the fourth decimal place, the smallest step most people count in — rose 192 pips above it by Wednesday evening, and closed on Friday 14 pips above it. Every number in that sentence is a distance from one price. That is what the weekly open is for: the line the week is measured from.

The starting line

The picture is the starting line of a race. The line itself is nothing, white paint on the track, but every distance in the race is measured from it, and nobody asks where a runner is, only how far from the line. The weekly open is the starting line. The week's high is 192 pips past it, the week's low 11 pips behind it, Friday's close 14 pips past it. Those distances are the week, told from one fixed point that everyone can see.
