What it is
Open interest is the total number of contracts open in a market — the size of the crowd, counted the same way for every futures market on earth. This panel teaches you to read one thing and one thing only: is the crowd arriving or leaving, and how fast. In Gold, participation has been expanding for a third straight week.
What it measures
Three numbers from the weekly report (2026-07-07): OPEN INT 371,776 — the contract count itself; OI %ILE 18 — where that count sits in its trailing 3-year range (18th percentile = a historically thin crowd); and WK ROC +0.6% — this week's rate of change. The QUICK READ verdict — EXPANDING / STEADY / THINNING — comes from a smoothed 3-week rate of change with a volatility-scaled dead-band, so a single noisy week can't flip the state, and the streak counts how many consecutive weeks the direction has held.
Why it's useful to you
Participation is the fuel gauge behind price. A move backed by a growing crowd has conviction — new money is funding it. The same move on a shrinking crowd is running on fumes: positions closing, nobody new arriving. Gold's read — expanding, but only from the 18th percentile — says fresh interest is returning to a thin market. One discipline this panel enforces: rising OI is not bullish by itself. Whether that new money is fresh longs or fresh shorts needs price direction — deliberately saved for Tier 2.
The 10-second read
QUICK READ chip first — EXPANDING, STEADY or THINNING — then the streak. Growing crowd = funded moves; shrinking crowd = fading conviction. That's the whole panel.

Market picker. Gold selected. OI is market-wide — no group toggle here, because open interest belongs to everyone at once.
2
Stat chips. OPEN INT 371,776 · OI %ILE 18 · WK ROC +0.6%. Size, historical rank, and this week's change — the whole panel in three chips.

Verdict banner. "Participation expanding for a 3rd straight week." The conclusion in plain English, streak included.
4
Window tabs. 6M / 1Y / 3Y / 5Y / 10Y / All — lookback for the charts below. Display only; the verdict math doesn't change.
5
QUICK READ chip. The three-state participation verdict: EXPANDING, 3 straight weeks at +0.6%/wk. Built on a smoothed rate of change with a dead-band, so it means a trend, not a blip.
6
OI vs price overlay. Open interest (gold line) drawn against price (white) over the selected window. Watch whether rallies and declines happen on a growing or shrinking crowd — that's the habit this chart builds.
7
Rate-of-change bars. Week-over-week % change in OI: teal = money arriving, red = money leaving. Streaks of one color are what the QUICK READ chip is summarizing.

✦ AI — "Reading participation." A cached note per CFTC release describing the crowd's size and direction — and deliberately stopping short of interpreting price direction.

What it is / Why it matters cards. The built-in lesson: OI is the size of the crowd; participation is the fuel behind price.

COMING IN TIER 2 teaser. Pairing OI direction with price direction unlocks the four-state read — new longs vs short covering vs liquidation. That's Suite 2.7's job; here you just learn to see the crowd grow or shrink.
