Support and resistance
Price areas where the market has repeatedly changed its mind. Not lines with power of their own — records of where trading actually happened.

Zones, not lines
Drawn on a chart a level is a thin line, which makes it look precise. It is not. What actually exists is an area where buying repeatedly overcame selling, or the reverse — and that area has width, usually a good fraction of a daily range.
Treating a level as an exact price is the most common way traders get hurt by them: a stop placed one tick beyond a "line" is a stop placed inside the zone, where noise lives.
Why levels work at all
There is nothing magic in a number. A level holds because of what people did there: positions were opened, and those holders defend their entry; positions were closed, and those traders remember the price; orders were left unfilled, and they are still waiting.
That also explains why levels decay. The people who cared are gone after a while, and a price that mattered three months ago may mean nothing today.
How levels are identified
Different methods find different things, and the terminal shows several side by side:
- Swing highs and lows — the raw record of where price turned.
- Equal highs and lows — several turns at the same price, which also marks where stops now sit.
- Volume profile and POC — the prices where the most volume actually traded, rather than where price merely visited.
- Pivots and Fibonacci — computed levels; they work when enough participants watch them, which is a fact about attention, not about the maths.
When a level stops being one
A level that price passes through and holds beyond is no longer a level — it is history. The common follow-up is that it flips roles: old resistance becomes support, because the people who sold there are now wrong and want out at breakeven.
The honest way to use levels is as places where something is likely to HAPPEN — a reaction, a decision, a burst of volume — not as predictions of direction. What happens at the level is the information.
Common questions
- How exact should a level be?
- Treat it as a zone with real width. A good rule of thumb is the average daily range of that coin: if it moves 3% a day, a level is not a price, it is a band around one.
- Do levels work on all timeframes?
- They exist on all of them, but their weight differs. A level from the daily chart survives noise that erases a 15-minute one, so the timeframe you read must match the timeframe you trade.
- Why do levels stop working?
- Because the traders whose decisions created them have moved on. A level is a memory of activity, and memories fade — old levels need recent touches to still mean something.
