What is a supply and demand zone?

A supply and demand zone is a small patch of sideways candles, the base, that price left in a hurry. The speed of the exit is the clue: buying or selling there was strong enough to carry price a long way without a pause. A demand zone sits below the current price and launched a rally. A supply zone sits above it and started a drop.

The usual explanation is that large orders were not all filled inside the base, so some buyers or sellers may still be waiting when price comes back. Treat that as a working story, not something you can see: no chart shows the orders behind it. What you can see is where price paused and how hard it left.

The idea that price moves when supply and demand fall out of balance is old. It is one of the core laws of the method taught by Richard D. Wyckoff (1873–1934), an American market writer and early technical analyst. The zone vocabulary in this guide, such as rally-base-rally, is newer trading-education shorthand with no single agreed inventor. The trading glossary lists related terms.

Supply and demand zones vs support and resistance

Both mark prices where the market reacted, and both work best as zones rather than thin lines, as in the drawing below. The difference is where they come from. Support and resistance is found where price turned several times. A supply or demand zone is found where price started one strong move, and it is usually most interesting before it has been retested at all.

So a support level tends to gain attention with each clean bounce, while a demand zone tends to weaken with each visit. The two often overlap: the base before a rally becomes a swing low, and a swing low is support. When a demand zone and a support level share the same prices, the area has two reasons to matter.

Why a box and not a line? Hypothetical: a stock turned up from $37.45, $37.60 and $37.80 over a week. A line at $37.75 shows two breaks that were not breaks. A box from $37.45 to $37.80 holds every reaction and puts the invalidation where it belongs, below $37.45.

The four formations: rally-base-rally, drop-base-drop, drop-base-rally, rally-base-drop

Every zone has three parts: a leg in, a base and a leg out. The leg out sets the type: a rally out makes demand, a drop out makes supply. The leg in tells you whether the zone continues a trend or marks a turn. Traders often shorten the four names to RBR, DBD, DBR and RBD.

Hypothetical drop-base-rally: a stock falls from $66.00 to $61.50 during the morning, trades between $61.10 and $61.85 for three 15-minute candles, then rallies to $63.90 in four large green candles. The three small candles are the base, and the prices they cover form a demand zone. This guide follows that stock through every step below.

Continuation zones (rally-base-rally, drop-base-drop) go with the trend already in place. Reversal zones (drop-base-rally, rally-base-drop) mark a turn, so check that the higher timeframe supports the new direction before you trust one.

Rally-base-rally (RBR)
Price rises, pauses in a small base, then rises again. The base is a demand zone that continues an uptrend.
Drop-base-drop (DBD)
Price falls, pauses, then falls again. The base is a supply zone that continues a downtrend.
Drop-base-rally (DBR)
Price falls, pauses, then rallies hard. The base is a demand zone at a turn from down to up.
Rally-base-drop (RBD)
Price rises, pauses, then drops hard. The base is a supply zone at a turn from up to down.
Base
One to a handful of small candles with overlapping ranges, just before the strong move. A long, wide base is a range, not a zone.

How to draw supply and demand zones

A zone has two edges. The proximal edge is the near side that price meets first on the way back: the top of a demand zone, the bottom of a supply zone. The distal edge is the far side. Most traders put the distal edge at the most extreme wick of the base, because trading through that wick means the zone failed.

For the proximal edge, choose one rule and keep it. The highest candle body in the base gives a tighter zone and a smaller stop, but price will sometimes turn just above it and leave without you. The highest wick gives a wider zone that fills more often, with a bigger stop. Neither is correct; switching between them from chart to chart is what makes your records useless.

In the example, the base bodies run from $61.30 to $61.70 and the wicks from $61.10 to $61.85. With the body rule the demand zone is $61.10–$61.70; with the wick rule it is $61.10–$61.85. This guide uses the body rule from here on.

  1. Find a strong move: several large candles in one direction, leaving an area quickly. A slow drift away does not count.
  2. Look just before it for the base: one to a handful of small candles with overlapping ranges.
  3. In TradingView, pick the Rectangle tool and draw from the distal edge (the extreme wick) to the proximal edge (your body or wick rule).
  4. Double-click the box and turn on Extend right in its settings, so the zone carries forward to today's candles.
  5. Note the timeframe on each box, and delete any zone that a candle has closed through.

Fresh vs tested zones: how to rate a zone

A fresh zone is one price has not come back to since it formed. Many traders treat the first return as the cleanest chance, on the reasoning that each visit fills some of the orders left behind. A zone tested twice or three times is more likely to give way. There is no fixed count; the point is that a zone wears out with use.

Freshness is one check among several. Run each zone through the list below and skip any that fails more than one.

  • Departure: a fast move of several large candles away from the base. The stronger and longer the move, the clearer the imbalance.
  • Base: short and tight. A few candles in a narrow range beat a long sideways stretch.
  • Freshness: untouched, or touched once, beats tested several times.
  • Timeframe: a zone from the 1-hour, 4-hour or daily chart outranks one from the 5-minute chart.
  • Room: the opposite zone sits far enough away to pay the reward you require, such as twice the risk.

Why higher-timeframe zones come first

A 5-minute demand zone means little if price sits just under a daily supply zone. Mark zones from the top down: daily first, then 1-hour, then your trading timeframe, the routine described in multi-timeframe analysis. When a small zone sits inside a big one pointing the same way, it deserves attention. When they point against each other, treat the bigger one as the one in charge. The bigger trend also picks your side: demand zones in an uptrend, supply zones in a downtrend.

Hypothetical: on the daily chart a stock has a fresh supply zone at $88.40–$89.20. On the 15-minute chart a tidy rally-base-rally demand zone forms at $86.10–$86.50. Buying near $86.50 with a stop at $85.95 risks $0.55, and a target just under the daily supply, at $88.35, is $1.85 away. That is room. The same 15-minute zone formed at $88.00 would aim straight into the daily supply with almost no room, so you would skip it.

Wait for confirmation at the zone

A zone is a place to watch, not an order. A resting limit order at the proximal edge gets the best price but also buys every zone that fails. A confirmation entry waits for a closed candle showing the zone holding: a worse price and some missed trades, but zones that slice straight through are filtered out.

The drawing below shows two common confirmations. Left, a pin bar: a long lower wick pushes through the level and the candle closes back above it. Right, an inside bar breakout: a large mother bar, a smaller inside bar within its range, then a close above the mother bar's high. A bullish engulfing candle also qualifies; the candlestick patterns guide covers the shapes, and price action trading shows how to read them in context.

Only a closed candle counts. Hypothetical: price dips into the $61.10–$61.70 zone and, ten minutes into a 15-minute candle, shows a long lower wick from $61.25. In the last minutes sellers return and the candle closes at $61.05, below the zone. The pin bar you saw never existed; the close made it a break. Judge the candle when it closes, and act on that.

Stop and target: beyond the zone, toward the opposite zone

The zone hands you the plan. The stop goes beyond the distal edge with a small buffer, since trading through the far wick means the zone failed. The target goes just in front of the opposite zone: under the next supply zone for a long, above the next demand zone for a short. Then divide reward by risk, and skip the trade if it falls short of your minimum. The stop loss and take profit and risk/reward ratio guides cover both in depth.

Hypothetical, worked through: after the rally, the stock paused at $63.45–$63.90 and dropped hard, a rally-base-drop supply zone. The drop brings price back to the $61.10–$61.70 demand zone for the first time. A 15-minute pin bar dips to $61.25 and closes at $61.80, and you buy at $61.80. Stop at $61.00, $0.10 under the distal edge: $0.80 of risk a share. Target at $63.40, just under the supply zone: $1.60 of reward. That is a 1:2 plan.

Size from the stop. A $25,000 account risking 0.5% per trade accepts a $125 loss: $125 ÷ $0.80 = 156.25, rounded down to 156 shares, about $9,640 of stock. At the target, 156 × $1.60 = $249.60, or +2R. At the stop, 156 × $0.80 = $124.80, or −1R, plus costs. A stop becomes a market order once triggered, so a gap can fill it beyond your price. The position size calculator does this math.

UpTickFlow, our invite-only TradingView indicator, does not look for these formations, so weigh this accordingly. It applies the same final steps: it waits for a candle to close at a level, draws the entry, stop and target before the trade, scores the setup from 0 to 100 and stays quiet in chop or when there is no room to the target. Use it as a second check on zones you marked yourself, not as a scanner.

How supply and demand zones fail

Zones fail often, and a failure should look as planned as a win. Same stock, same $61.10–$61.70 zone, another day: the pin bar forms and you buy at $61.80 with the stop at $61.00. Two candles later sellers return and price trades through $61.00. The stop fills there, or lower in a fast market: about −1R, or $124.80 on 156 shares. That loss was sized before the entry, which is the whole job of the stop.

When a candle closes beyond the distal edge, the zone is finished: delete it rather than redrawing it lower. Some traders then watch it from the other side, the way broken support can turn into resistance.

The usual reasons a zone fails:

  • It had been tested before, perhaps more than once, and the orders there were used up.
  • It fought the higher-timeframe trend, or sat inside a bigger zone pointing the other way.
  • The "base" was really a long range, so the zone was too wide for a sensible stop.
  • Earnings or major news hit while price was at the zone; scheduled events can override any chart level.
  • It was drawn after the fact. Every rally starts somewhere, so in hindsight every low looks like a demand zone. Mark zones before price returns, not after it reacts.
  • The entry came before the candle closed, or the stop was nudged lower as price approached it.
