Who it's for — Anyone drawing levels on the chart who wants to know when a level truly «holds» — and when a break has enough participation.
Support is a price band where demand stopped or reversed a decline. Resistance is where supply stopped or reversed a rally. They are not magic lines: memory of past negotiation, often reinforced by volume and nodes on Volume Profile.
In plain terms — Support = «floor» where price bounces; resistance = «ceiling» where it is rejected. They hold until someone crosses with conviction.
How levels form
| Origin | Example |
|---|---|
| Prior highs/lows | Double top, swing low |
| Consolidations | Area with heavy volume |
| Profile | POC, HVN, Value Area edge |
| Round numbers | 100, 50,000 — psychological barriers |
| Trend line | Dynamic support/resistance |
Volumetric confirmation
| Signal | Reading |
|---|---|
| Bounce on high volume at support | Demand present |
| Break with rising volume | More credible breakout |
| Break on low volume | |
| High volume, little movement |
Common mistake — Buying support «because it always holds» — news, gaps, or thin liquidity can slice through without respect.
Example — Stock tests €24 three times with rising positive delta: live support. Break above €28 on falling volume: wait for retest or confirmation before chasing.
Summary card
- Support: demand zone / pause in decline.
- Resistance: supply zone / pause in rally.
- Rule: level + volume + structure together.
