Supply and Demand Trading: Marking Zones That Are Worth Marking
A supply or demand zone is the area price left in a hurry. The marking rule is simple; the discipline is in keeping only the few zones that came from a move worth respecting.
A demand zone is the small consolidation immediately before price accelerated upwards; a supply zone is the base before a sharp fall. Mark the range of those few candles, keep it tight, and only keep zones left by a move that actually changed the chart. A zone is a location to watch, not a signal, and most are used up on the first return.

Open EURUSD with Power POI →What a zone is
A demand zone is the small area of consolidation - the base - immediately before price accelerated upwards. A supply zone is the base before a sharp fall. The reasoning is that not everyone who wanted to trade at that price got filled before the move, so the area may matter again when price returns.
How to mark one
- Find a move that left the area decisively, not a drift.
- Go back to the consolidation just before it started; mark the range of those few candles.
- Keep the zone tight. A wide zone is unfalsifiable and useless for a stop.
- Note whether the departure broke structure - see BOS and CHoCH. A zone whose move changed the trend is worth more than one that produced a small wiggle.
- Delete zones price has already worked through. Old ones clutter the chart and the judgement.
Marking zones is a judgement you build by repetition. Chart Bound gives you the repetitions free, on real historical charts.

They overlap heavily. Support and resistance are defined by repeated touches; supply and demand zones are defined by the move that left; an order block is a narrower version of the same idea, keyed to the last opposing candle. Different traditions, similar locations on the chart - which is a fair reason to be sceptical of anyone claiming one is objectively better.
When zones fail
- Used up on the first return. Whatever interest was there can be filled once. Third and fourth tests are weaker, not stronger.
- Drawn everywhere. Every chart has dozens of candidates; a chart with twenty zones has none.
- Against the trend. Buying demand inside a strong downtrend is a counter-trend trade wearing a technical label.
- Too wide. A zone a third of the daily range tall will always be "respected", which means it tells you nothing.
- Regime change. A zone from a quiet period has little meaning once volatility doubles.
- Hindsight. If you could not have marked it before price returned, it did not predict anything.
Turning a zone into a trade
A zone is a location, not a signal. Wait for behaviour at it - a rejection, a sweep and close back inside, a shift in structure - then place the stop beyond the zone and size from that distance with the lot size calculator.
Frequently asked questions
What is the difference between supply and demand and support and resistance?
Support and resistance are defined by repeated touches of a level; supply and demand zones are defined by the base a strong move left behind. In practice they often mark the same areas.
How do I draw a supply and demand zone?
Mark the small consolidation immediately before a decisive move away, keep it tight, and only keep zones from moves that actually changed something on the chart.
Do supply and demand zones work?
They are a way of choosing locations, not a strategy. The same zone can hold once and fail the next time, so the plan, stop and size still decide the outcome.
How many times can a zone be used?
Usually once with any conviction. Each subsequent test has less unfilled interest behind it.
