Supply and demand zones are price areas on a chart where institutional buyers or sellers previously entered the market in large enough size to cause a significant move, leaving behind unfilled orders that pull price back when it returns. Unlike a support or resistance line drawn at a single price, a zone spans an area — typically 10-30 pips wide on EUR/USD or GBP/USD, and 30-60 pips on volatile pairs like GBP/JPY — because institutions cannot fill large positions at one price without moving the market against themselves.
Key Takeaways
- Draw zones from candle bodies, not wicks — the body marks where orders were filled, the wick is noise.
- Fresh zones (never retested) carry the highest probability; each revisit reduces the pool of unfilled orders.
- Timeframe hierarchy determines authority: a daily demand zone overrides a conflicting 1H supply zone.
How Supply and Demand Zones Work
The concept originates from Sam Seiden, a former Chicago Mercantile Exchange trader who observed that institutional orders at specific price levels remain partially unfilled after price moves away sharply. When price returns to that level, the remaining orders are triggered — creating a reaction.
The four zone patterns to recognize:
- Rally-base-rally — price rises, consolidates briefly, then surges again. The base is a demand zone.
- Drop-base-rally — price drops, consolidates, then reverses sharply upward. Also a demand zone.
- Rally-base-drop — price rises, consolidates, then collapses. The base is a supply zone.
- Drop-base-drop — price falls, consolidates, then continues lower. Also a supply zone.
How to draw a zone correctly:
Locate the last candle body before the explosive impulse move. Draw the zone from the open to the close of that body. Never extend to the wick — wicks represent temporary price discovery, not order placement. A zone formed from fewer than 3 consolidation candles is considered higher quality because less time passed for opposing orders to accumulate and absorb the imbalance.
Zone invalidation: A zone is broken when price closes beyond its far edge. A wick through the zone is not invalidation. Until a candle closes outside the boundary, the zone remains active.
Timeframe hierarchy: Daily zones carry more institutional weight than 4H zones, which outrank 1H zones. Lower timeframe entries should align with higher timeframe zone direction — entering a 15-minute demand zone that sits inside a daily supply zone is a low-probability trade.
Practical Example
EUR/USD is in a daily uptrend. On the 4H chart, price drops from 1.0950 into a base between 1.0820 and 1.0840, consolidates for 2 candles, then rallies sharply to 1.0990 — a 150-pip impulse. This base is a demand zone following a drop-base-rally pattern.
The zone is drawn from the last bearish candle body before the rally: open 1.0842, close 1.0821. The zone spans 1.0821-1.0842, approximately 21 pips wide.
Two weeks later, price pulls back into the zone. A trader enters long at 1.0835 with a stop at 1.0810 — 25 pips below the zone — and a target at 1.0960, 125 pips away. That is a 5:1 risk-reward ratio. On a $10,000 account risking 1% ($100), position size is 4 mini lots (pip value = $1.00 per mini lot × 4 lots = $4.00/pip; risk = 25 pips × $4.00 = $100). The zone holds, price reaches target.
Supply and demand zones are price areas where institutional traders left unfilled orders, causing price to return and react when it revisits those levels. Zones are drawn from candle bodies, not wicks, and are typically 10 to 30 pips wide in major forex pairs.
Common Mistakes
- Drawing from wicks instead of bodies. Wick extremes capture failed tests, not order clusters. The body defines where transactions occurred at scale.
- Trading retested zones without confirmation. Each test of a zone consumes more of the waiting orders. A zone on its third visit has significantly less unfilled order inventory than a fresh zone.
- Ignoring timeframe conflict. Entering a 1H demand zone while a daily supply zone sits just above is fighting institutional order flow. Always identify the higher timeframe context before marking lower timeframe zones.
- Treating a wick close as invalidation. Only a full candle close beyond the far edge of the zone confirms it is broken. Premature removal leads to missing valid setups on the retest.
How PipJournal Tracks Supply and Demand Zones
PipJournal lets traders tag each entry with a setup type — logging a trade as “demand zone / 4H / EUR/USD” takes seconds. After 20 or more tagged trades, the analytics dashboard surfaces win rate, average risk-reward ratio, and session breakdown by setup type, revealing whether London open or New York overlap produces stronger zone reactions on your specific pairs. This converts a subjective chart concept into measurable, personal edge data.
