How it works: axes, quadrants, and methodology

How to read this chart

Each dot is a sector, a basket of Grand Exchange items. Its position shows how the basket is doing against the market, measured by the QS Liquid 200, a list of 200 heavily traded items. It does not show the basket's price on its own.

What the two axes mean

Across: RS-Ratio

Relative strength is the sector's prices divided by the market's. It rises when the sector gains on the market and falls when it loses ground. RS-Ratio compares its 7-day average with its 28-day average, and 100 is the dividing line. Right of 100, the last 7 days have been stronger than the last 28. Left of 100, weaker.

Up and down: RS-Momentum

RS-Momentum asks whether RS-Ratio is rising or falling. Above 100, today's RS-Ratio is higher than it was seven days ago. Below 100, it is lower.

What the four quadrants mean

The two lines at 100 split the chart into four areas.

Sector rotation chart quadrants Four quadrants. Top right is Leading, bottom right is Weakening, bottom left is Lagging, top left is Improving. Dots usually move clockwise: Improving, Leading, Weakening, Lagging. Improving Leading Lagging Weakening 100 100 RS-Momentum RS-Ratio

Leading

Stronger than its 28-day average and still rising.

Weakening

Still stronger than its 28-day average, but lower than a week ago.

Lagging

Weaker than its 28-day average and still falling.

Improving

Weaker than its 28-day average, but higher than a week ago.

A sector with less than 35 days of history has no dot yet. It is listed under the chart as Warming up.

Dots and tails

The dot is where the sector stands today. The tail behind it covers the last four weeks, with one marker for each week.

The usual path runs clockwise: Improving, Leading, Weakening, Lagging, then back to Improving. A sector can turn around or skip a quadrant at any point.

A long tail means the sector's position changed a lot over the month. A short tail means it barely moved.

Ways to use it

  • Pick where to look first. Start with sectors in Leading or Improving, then open the items in their baskets, listed further down, to check individual prices.
  • Review what you hold. If your stock sits in a Weakening or Lagging sector, check whether the item is still worth tying up GP in.
  • Watch for turns. A dot crossing one of the lines, such as Lagging to Improving, is a cue to look at that sector's items.
  • Test a hunch. If you expect a sector to move, see whether the chart already shows it ahead of the market.

A caution

This chart shows relative momentum, not a price forecast. A sector can be Leading while its prices fall, if the rest of the market falls faster. It also covers baskets, so an item can behave differently from its sector, and it says nothing about an item's margin or buy limit.

Calculation formulas

RS-Ratio = 100 × 7-day average relative strength ÷ 28-day average relative strength. RS-Momentum = 100 × today's RS-Ratio ÷ RS-Ratio seven days ago.

Sector rotation questions

Sector rotation FAQ

What is sector rotation?

It compares each equal-weight sector index with the equal-weight QS Liquid 200 benchmark index. Relative strength is the sector index divided by the benchmark index, times 100. RS-Ratio compares 7-day and 28-day relative-strength averages; RS-Momentum compares today's RS-Ratio with its value seven days ago.

How are sectors built?

Each item is assigned to one sector, and items have equal weight within that basket. A set counts as one item by its set id, not by its component pieces.

What is the QS Liquid 200 benchmark?

It is a frozen list of the top 200 items by 7-day traded value that pass the market noise filter. Each item has equal weight, and the list refreshes monthly. Items that also appear in a sector remain in the benchmark.

What do the four quadrants mean?

Leading means the 7-day relative-strength average is at least the 28-day average, and today's RS-Ratio is at least its value seven days ago. Weakening means the 7-day average is at least the 28-day average, but today's RS-Ratio is lower than seven days ago. Lagging means the 7-day average is below the 28-day average and today's RS-Ratio is lower than seven days ago. Improving means the 7-day average is below the 28-day average, but today's RS-Ratio is higher than seven days ago.

Why is Fractured Archive warming up?

A first dot needs 35 days of history. Fractured Archive items started trading on 2026-10-21, so its first dot is expected about 2026-11-25 and a full 4-week tail about 2026-12-23.

How often does the data update?

It updates daily after the last UTC day is complete. Dates and update times are UTC.
