The idea
When price leaves an area quickly with large candles, it suggests that many orders were filled there and some may still be waiting. Supply and demand traders mark that area, the base of a few small candles before the strong move, as a zone.
A demand zone sits under price, where a rally began; a supply zone sits above, where a drop began. The trade is the first return to a fresh zone: buy at the top of a demand zone, sell at the bottom of a supply zone, with the stop on the far side.
Watch it play out
Step by step
The rules
Setup
- A base of one to five small candles, followed by a strong move away (large candles, little overlap).
- The zone runs from the base's lowest low to the top of its highest body (for demand).
Entry
- A limit order at the top of a fresh demand zone (or the bottom of a supply zone), valid for the first return only.
Stop-loss
- Just beyond the far side of the zone.
Target
- The swing high (or low) before price came back, or 2R.
Filters that help
- Fresh zones only: each return weakens a zone.
- Prefer zones in the direction of the higher-timeframe trend.
Why it can work
Large buyers rarely fill everything at once. If a strong rally left orders unfilled, a return to the price where they were buying may find them again. The stronger the departure and the fewer times the zone has been revisited, the more likely orders remain.
It is a refinement of support and resistance: instead of a line, a band built from where the move actually started.
Worked example
EUR/USD bases between 1.0950 and 1.0965, then rallies 60 pips in a few strong candles. A buy limit goes at 1.0965 with the stop at 1.0945, 20 pips away, and the target at the rally's high of 1.1025.
Risking $100 that is 0.5 lots, aiming for $300 (3R) if the zone holds.
When it works, when it fails
Works best
With fresh zones behind strong, clean departures, in the direction of the bigger trend.
Struggles
When zones are drawn after the fact around every pause, and when price returns to a zone that has already been used. Two traders often draw the same zone differently, which makes honest testing hard.
Common mistakes
- Marking zones everywhere, so that every bounce looks like proof.
- Trading the third or fourth touch of the same zone.
- Drawing zones so wide that the stop is far away and the size tiny.
Variations
- Order blocks
- The Smart Money version: the last opposite candle before the strong move, rather than the whole base.
What the evidence says
Evidence: Popular, untestedWidely used, but no rigorous public testing. An idea to test yourself.
Supply and demand trading is popular and widely taught, but there is no rigorous public study of its rules, partly because the zones depend on judgement.
Treat it as a way to read charts and test on your own records: write down the exact rules for a zone, then check how first returns actually behaved.
Questions
- What is the difference between supply and demand and support and resistance?
- Support and resistance are lines where price turned. Supply and demand zones are bands built from the base a strong move started from, with an emphasis on the first return.
- How do I know a zone is strong?
- Traders look for a short base, a fast departure with large candles, and no return since. None of these makes a zone certain to hold; they are the conditions to test.
- Should I wait for confirmation in the zone?
- Some traders wait for a reversal candle inside the zone instead of a limit order. It filters some failures and misses some fast bounces.
