Concept
Support and Resistance
Support and resistance describe price areas where movement has previously slowed, stalled or reversed. They are observations about past behaviour at particular price areas, not physical barriers.
How to read it
- They are zones, not precise lines. Price commonly overshoots a level before turning, or turns before reaching it.
- Levels that have been tested repeatedly are watched by more participants, which is part of why reactions occur there at all.
- A level that price moves decisively through is often discussed as reversing role, but this is a description of subsequent behaviour rather than a rule.
What it does not tell you
- Identification is highly subjective. Two traders drawing levels on the same chart routinely produce different maps.
- Hindsight makes them look far more reliable than they are, because levels that failed are not remembered or redrawn.
- A level holds until it does not, and nothing about the level itself indicates which time is which.
Frequently asked questions
What is the difference between support and resistance?
Support describes an area beneath price where declines have previously slowed; resistance describes an area above price where advances have. The distinction is simply which side price is currently on.
Do support and resistance levels actually work?
They describe where reactions have happened before. Because many participants watch similar areas, activity does cluster there — but any specific level can be passed through without pausing.
Why do levels appear so accurate in hindsight?
Because levels are usually drawn after the reaction is visible. Selecting the areas where price did react, while ignoring where it did not, makes the technique look far more precise than it is in real time.

Educational use only
This page is educational material about how a technical tool is calculated and read. It is not investment advice, not a recommendation to buy or sell anything, and not a signal service. No indicator predicts future prices. CernoQuant is a trading journal and analytics platform, not a SEBI-registered investment adviser. Trading decisions and their outcomes are yours alone.
Indicators describe the market. A journal describes you.
Knowing how RSI is calculated is the easy part. The harder question is whether you actually followed your own rules — CernoQuant reads your executed trades and measures the gap between what you intended and what you did.
