Support and resistance zones

What it means

A support or resistance zone is a band of price that the market has turned at more than once. Support sits below the current price and resistance above it, and the same band changes name when price crosses it: a ceiling that gives way becomes a floor to be tested from above.

This publication draws them as BANDS and never as a single figure. A level quoted to the cent implies the market has agreed on a number, which it has not; what it has done is turn somewhere in a neighbourhood, more than once. The width of the band is that neighbourhood.

How we detect it

The engine needs at least thirty bars. It finds swing highs and lows, then clusters them: two swings belong to the same zone when they sit within 0.75 of one Average True Range of the cluster's mean. A cluster with only one swing in it is discarded — a zone requires at least two touches, because one turn is an event and two are a pattern.

The band runs from the lowest swing in the cluster to the highest, widened slightly at each edge. Strength rises with the number of touches and with how recently the most recent one happened, and the four strongest zones are kept. Because the clustering tolerance is measured in ATR, the same rule produces sensible bands on Bitcoin and on a large-cap equity without a threshold being tuned per market.

Price is called NEAR a zone when it sits inside the band, or within one ATR of the nearer edge.

When the read carries information

• The instrument has traded a wide enough range for swings to cluster at all — a market that has gone almost straight up produces few zones, and the engine reports few.
• The timeframe matches the question. A daily zone survives an hour of noise; a 15-minute zone does not describe where a week is likely to turn.
• Volume and volatility are ordinary. The band is drawn from where price turned before, and that history is most relevant while conditions resemble it.

When it misleads

• After a structural repricing — an acquisition, a policy shock, a token event — the earlier turns describe a market that no longer exists, but they are still on the chart and the clustering still finds them.
• In a strong trend, zones bunch behind price and the nearest one can be far away. A distant zone is a weak statement about what happens next.
• On a thinly traded instrument, a swing can be one print rather than a decision by many participants, and two such prints can form a zone that means nothing.

How it reaches you

On our surfaces a zone is described as ACTING as support or resistance right now — an observation about current behaviour, not a forecast that it will hold. Zones are the first thing the analysis order looks at, before any indicator.

Nothing here is a prompt to act. A zone is context for reading a chart, and this publication does not tell anyone what to do about one.
