Supply zone

In practice

Gold drops $30 in one candle from the $2,050–$2,055 band. That band is now a supply zone. When price later climbs back into it, a trader looks for a bearish reaction and a short entry with a stop above the zone's top.

Why it matters for traders

Supply zones mark where real selling pressure emerged, and price often returns there to be rejected again — giving short sellers a pre-mapped area to act in. They are stronger fresh and weaken with each test, so timing the first return into an untested zone tends to offer the cleanest trades.

Common pitfall

The pitfall is drawing supply zones too loosely — covering huge areas where any reaction is called a 'win' — and trading zones already tested many times. Supply zones are strongest fresh and weaken with each retest. Draw them tightly around the origin of the sharp move, prioritise untested zones, and confirm with a bearish reaction before shorting, rather than blindly fading into every band you can find.

Putting it in context

Price action concepts like this one work because they describe what buyers and sellers actually did, rather than what an indicator derived from those prices suggests. Used well, they anchor decisions in structure: clear levels where other participants are likely to act again. The skill that takes time is judging which structures matter on the timeframe you trade — a level obvious on the daily chart is usually significant, while most five-minute structures are noise. Mark your levels before the session, wait for price to reach them, and only then look for a signal. Trading every minor formation without that location filter is the most common reason beginners conclude price action 'doesn't work.'
