Supply Zone

A supply zone is a price area on a chart where traders expect selling pressure to emerge, potentially halting an upward move or triggering a decline. It is identified by looking at past price action where the market repeatedly struggled to rise above a certain level, showing that sellers were willing to enter at those prices.

How It Works

Technical analysts draw a supply zone by connecting the high points of several candlesticks that formed a short‑term resistance area. The zone is usually represented as a rectangle or a band between the highest high and the lowest low of those candles. When price approaches the zone from below, traders watch for signs such as bearish candlestick patterns, decreasing volume, or indicator divergences that suggest sellers are gaining control. If the price breaks through the zone with strong buying volume, the supply zone may be invalidated and turn into a support area.

Why It Matters

Recognizing a supply zone helps traders plan entries, set stop‑loss orders, and define profit targets. For example, if a stock has been rising and approaches a previously identified supply zone at $50, a trader might decide to take partial profits or place a stop just above the zone to protect against a sudden reversal. Understanding supply zones also complements other concepts like resistance and demand zones, providing a clearer picture of where market forces are likely to shift.
