A support level is a price area where buying interest has historically been strong enough to halt or reverse a decline. Visually it shows up as the floor of a range, a prior swing low that price tested and bounced from, or a moving average that price has respected repeatedly.
Support is not a single line — it is a zone. The cleaner the prior reaction (sharp bounce, high volume, multiple touches), the more confident traders are placing trades around the level.
When a support level breaks (a clean close below it), it often flips polarity and becomes resistance on the way back up. Re-tests of broken support are common short-side entries.
Esempio
BTC bounces from 48,000 three times over two weeks. 48,000 is acting as support. A close below 48,000 would invalidate that read and flip it to resistance.
