How a zone forms
A demand zone is born when price pauses in a tight base and then explodes upward: the base is where buyers absorbed the last selling and loaded positions. A supply zone is the mirror: a base followed by a breakdown. The four classic shapes: rally-base-rally and drop-base-rally create demand; drop-base-drop and rally-base-drop create supply.
The zone is drawn around the base — from the extreme wick of the basing candles to the edge of the bodies — not around the whole move. Tight bases (one to three candles) are better than long chop: they show decisiveness, not indecision.
Grading a zone: departure, freshness, time
Three questions grade any gold S/D zone. How did price LEAVE? Explosive departure (big candles, structure broken, an FVG left behind) means real imbalance; a drift away means nothing was there. Has it been touched? A fresh, never-revisited zone holds the most unfilled orders; each test spends them. How fast was the return? A zone revisited immediately is weaker than one price took its time returning to — instant returns often mean the move had no real sponsorship.
Score high on all three and you have an A-zone worth planning around. Fail the departure test and the zone should not be on your chart at all.
Zones vs order blocks: same family
Traders argue endlessly about S/D zones versus order blocks; in practice they describe the same institutional footprint at different resolution. The OB is the sharpest candle of the base; the S/D zone is the whole base. On this site's chart engine, the two are literally scored together — a zone whose evidence stack includes an OB, an FVG and a liquidity sweep outranks a zone with any single ingredient.
The practical takeaway: do not trade a zone because it exists; trade it because multiple independent footprints stack in the same place.
Trading the return
The base pattern: price returns to a graded zone, you demand a lower-timeframe reaction (a sweep of the minor low into the zone, then a shift back), enter on confirmation, stop beyond the zone's far edge plus an ATR buffer, target the opposing liquidity. Fresh zone + trend direction + correct side of equilibrium = the trade you size normally. Anything less = smaller or skipped.
And accept the honest number: even A-zones fail regularly. The edge is that winners at 2R-3R outweigh 1R losers, which only survives if the stop is always taken.
See it live
The XAUUSD live chart maps supply and demand zones automatically with this full lifecycle: base detection, departure strength, freshness, test count, tap-and-go rejections, flips into breaker zones, and a letter grade per zone — updated on every closed candle, from the 5 min to the weekly. Pull it up, toggle S&D, and audit your own zones against the engine's.
Levels are location. Whether TODAY is the day to act on them is context — that is what the daily prediction covers each morning.
FAQ
What is the difference between fresh and tested zones?
A fresh zone has never been revisited since forming, so its resting orders are intact — highest probability of reaction. Each test consumes orders; after two or three touches a zone is usually spent and due to break.
How wide should I draw a gold supply/demand zone?
Around the base only: extreme wick to the edge of the candle bodies. On H1 that is typically a few dollars. If your zone is 30 dollars wide, it is a region, not a zone, and the stop distance will destroy your risk-reward.
Do supply and demand zones repaint?
Hand-drawn ones do not; indicator versions sometimes do. The engine on this site only builds zones from closed candles and removes them on close-based invalidation, so what you see is what history actually was. Nothing here is financial advice.
