Levels versus zones
Support describes an area where buying has previously appeared; resistance describes an area where selling has previously appeared. Markets rarely respect a single exact line every time.
Finding meaningful areas
Mark repeated reactions, prior highs and lows and areas of consolidation on a consistent timeframe. Avoid drawing so many zones that every price appears important.
Role reversal
After a convincing break, a prior resistance area may later act as support, or vice versa. This is a possibility to observe, not a rule that always holds.
Invalidation and uncertainty
A zone is weakened when price repeatedly trades through it. Define in advance what evidence would invalidate the interpretation.

Worked example
If price reacts near 2,000 several times, mark a zone such as 1,995–2,005 rather than claiming an exact guaranteed floor.
Try it yourself
On historical gold or BTC data, mark two zones and document each reaction and failure.
Independent activity
Create a screenshot annotation explaining one successful reaction and one failed reaction at a level.
