Supply and demand zones: how to mark and trade them in futures
A supply or demand zone is the base price left with force. Here is how to mark it with a fixed convention, how the first return is traded and what the evidence says.
A demand zone is the place price left with force to the upside. A supply zone is the same to the downside. To mark one you look for two things: a base of a few small, overlapping candles, and a departure of large candles that move away fast. The base is the zone.
The method was popularized by the school of Sam Seiden and Online Trading Academy (OTA). Its central rule is to trade only the first return of price to a quality zone, with the entry at the near edge (proximal), the stop behind the far edge (distal) and a target before the opposing zone.
In this guide you will see how zones are marked step by step, the four patterns (RBR, DBR, DBD and RBD), the classic system with its rules, the most repeated mistakes, what the evidence says and how the method fits a futures prop firm account.

What are supply and demand zones
The OTA school's idea is that, in a base with an explosive departure, there was a strong imbalance between buyers and sellers and some orders were left unfilled. When price returns, those orders would slow it down. That is the story of the method. Nobody has measured that those institutional orders exist: the retail trader does not see the institutional book.
In the most widespread version of the method, patterns are named for the leg arriving at the base and the leg leaving it:
| Pattern | Arrival | Departure | Zone type |
|---|---|---|---|
| RBR (rally-base-rally) | Up | Up | Demand (continuation) |
| DBR (drop-base-rally) | Down | Up | Demand (reversal) |
| DBD (drop-base-drop) | Down | Down | Supply (continuation) |
| RBD (rally-base-drop) | Up | Down | Supply (reversal) |
Supply and demand versus order block
They look alike, but they are not the same:
- Order block (ICT): the last opposing candle before an impulse. It requires displacement and a structure break, and it is invalidated when price closes on the other side of the block.
- Supply or demand zone: the whole base. It needs no structure break or FVG, and it holds until a clean close on the other side.
The order block is narrower and easier to invalidate. The zone is wider: it "forgives" more, in exchange for a worse price. We explain the order block in its own guide: order block and market structure.
How to mark supply and demand zones step by step
1. Read the context on three timeframes
Seiden uses three timeframes: the highest tells you whether price is in supply or in demand (the "curve"), the middle one gives the trend and the lowest the entry. The timeframes are separated by a factor of 4 to 6. For example, daily, 240 and 60 minutes. For intraday futures, a combination with the same proportion would be 240, 60 and 15 minutes.
2. Look for the departure first and then the base
It is the most useful rule to avoid drawing zones on any consolidation. The departure is a run of strong candles in one direction; a slow drift does not count. The base is one to a few overlapping candles right before it.
A programmable criterion: a base candle with a body of at most 50% of its range, and a departure candle with a body of at least 50-60%.
3. Draw the proximal and the distal
There is no single convention. Some schools use wicks and others use bodies, and some include the arrival leg in the distal of a DBR. The choice changes the size of the stop, so it is best to fix one and not change it.
In this guide we use the same one as our indicator:
- Proximal (near edge): the bodies of the base candles. On a demand zone, the highest body of the base; on a supply zone, the lowest.
- Distal (far edge): the most extreme wick of the base. On a demand zone, the low; on a supply zone, the high.
The stop goes behind the distal.
4. Classify the zone
RBR and DBR are demand. DBD and RBD are supply. The reversal ones (DBR, RBD) and the continuation ones (RBR, DBD) are marked the same way.
5. Score the zone
OTA measures quality with the "odds enhancers": strength of the departure, time at the base (fewer candles, better), freshness, profit margin, trend and position on the curve. OTA's official points table is not public.
6. Trade only the first return
Buying during the initial departure is what Seiden calls the "sucker bet". You wait for price to come back to the zone.
Systems with rules for supply and demand zones
OTA Core Strategy
Sell at quality supply and buy at quality demand. The execution rules are "set it and forget it": everything is placed before price arrives.
| Element | Rule |
|---|---|
| Entry | Limit order at the proximal, on the first return to a fresh zone |
| Stop | Beyond the distal |
| Target | Before the opposing zone, not right at it |
| Minimum margin | At least 3:1 to the first target; "if the chart offers 3:1, look for 4:1" |
| Trend filter | In 2012, Seiden used a 20-period average; other OTA instructors use higher highs and higher lows |
| Time filter | The method has none; intraday, stay away from news windows (see below) |
| Management | Orders placed in advance; do not chase price |
Curve filter
The curve is the corridor between the fresh supply and demand of the higher timeframe, divided into thirds, according to the usual description of the method:
| Position on the curve | What to trade |
|---|---|
| Low third (cheap) | Longs only |
| Middle third (equilibrium) | Nothing, or a reduced target |
| High third (expensive) | Shorts only |
Full checklist in seven lines
- Curve timeframe: are you in the low third or the high third?
- Trend timeframe: is the trend in your favor?
- Fresh zone, with a short base and a strong departure.
- Favorable position on the curve.
- Margin of at least 3:1 to the opposing zone.
- Limit at the proximal, stop behind the distal.
- Exit before the opposing zone.
Variant: the flip
A demand zone that breaks with a clear close can start acting as supply on the first return, and vice versa. The explanation given is triggered stops and trapped longs who want out on the first return. It is an idea from OTA teaching that circulates in summaries; we could not verify it in a primary source. There are public scripts that implement it with rules: first close through, zone pending; second close, reversal confirmed.
Common mistakes with supply and demand zones
- Zones that are too wide or too narrow. Wide ones lose entry and stop precision; narrow ones miss valid reactions.
- Too many zones. The best-rated public scripts limit themselves to about 5 per side. If everything is a zone, nothing is.
- Ignoring freshness. For the classic school, each visit consumes interest and, after 3 or more tests, the zone is considered broken.
- Accepting deep penetrations. Brandon Wendell (OTA) does not want to see a penetration of more than 50%, though he clarifies that "it is a guideline, not a rule".
- Entering on the departure. It is the "sucker bet". The entry is on the return.
- Placing the target right at the opposing zone. Seiden recommends exiting before.
- Timeframes without hierarchy. Identifying on one timeframe and executing on another without order gives early entries or late exits.
- Believing your zone is the zone. Two traders rarely draw the same zone. That is why you need to fix a convention and respect it.
What to combine supply and demand zones with
- Volume profile: a zone that coincides with an HVN or the POC is an acceptance zone, where price tends to slow down and rotate. A zone with an LVN in front of it is a zone price can reach quickly. You have it in volume profile.
- Structure: in the usual reading of the method, departures that break a previous swing carry more weight. We explain it in order block and market structure.
- Levels everyone sees: session highs and lows and round numbers. It is the confluence with the most backing, because orders cluster at those levels (Osler, New York Federal Reserve) and supports and resistances coincide with peaks of order book depth (Kavajecz and Odders-White, 2004). Session levels are in ICT killzones.
- VWAP: some people recommend combining zones with session data, without providing proof. If you use it, make it a location filter: VWAP trading.
No source has measured that adding these confluences improves the results of zones.
What the evidence says about supply and demand
There are two data points worth knowing:
- Levels react slightly more than chance, but it was not shown that they make money. Carol Osler (New York Federal Reserve, 2000) compared the levels of six firms in three currency pairs with 10,000 sets of random levels. Published levels bounced in 60.8% of cases versus 56.2% for random ones. In addition, no firm was able to tell which levels were stronger (FRBNY).
- Freshness is in doubt. Chung and Bellotti find that more previous bounces increase the probability of a bounce, the opposite of what the fresh-zone doctrine says (arXiv 2101.07410). These are studies on supports and resistances in general, not on the base-plus-departure pattern, but the conflict exists.
There is no public, reproducible backtest with costs of the OTA pattern on futures. The win rates circulating on blogs have no sample. As a useful reminder, even though it is a study of support and resistance in FX and not a universal baseline: in Osler's data, even random levels bounced about 56% of the time. A high win rate means little until you compare it with what chance would do.
Some context worth knowing: in 2020 the FTC sued Online Trading Academy over false or unsubstantiated earnings claims in its marketing, and the case was closed with a settlement (FTC). The case was about how courses were sold, not about how zones are drawn.
How supply and demand zones fit a prop firm
The height of the zone is your risk per contract. From the proximal to the distal, plus a small margin, is what you lose if the stop is hit. With CME values:
| Contract | Example zone | Risk per contract | In micro |
|---|---|---|---|
| NQ ($20/point) | 20 points | $400 | MNQ: $40 |
| ES ($50/point) | 5 points | $250 | MES: $25 |
| CL ($10/tick of 0.01) | 0.30 | $300 | $30 |
| GC ($10/tick of 0.1) | 5.0 | $500 | $50 |
With a daily loss limit of, say, $1,000, two full stops on GC with one contract (2 x $500) use up the entire limit in this example, and two on NQ ($800) most of it. On micros, a tenth of that. Size by the height of the zone, not by a fixed number of contracts, and discard the zones that do not fit.
Limit orders and news. "Set and forget" leaves limit orders waiting, sometimes for hours. Many prop firms restrict trading around news such as CPI or NFP, and some consider being flat to include having no pending orders, even if they do not fill. Check the rules of yours and, if needed, cancel and replace orders around CPI, NFP, FOMC and crude oil inventories.
CL and GC. Crude oil inventories and macro data create very wide zones. And the gap from the daily 16:00 to 17:00 CT pause can create false "departures" on the reopen. Be wary of zones born there.
3:1 margin and consistency. Requiring 3:1 to the opposing zone with wide zones pushes the target farther away. Intraday that reduces the tradable zones, which favors discipline. But a system with a distant target concentrates profit in a few large trades, and that can clash with your firm's consistency rules.
If you want to compare daily losses and rules across firms, use the prop firm comparator.

Supply and demand zones FAQ
How do you mark supply and demand zones?
Look first for a strong departure and then for the base of a few candles right before it. The base is the zone: proximal on the bodies, distal on the most extreme wick.
What are the proximal and the distal?
The proximal is the edge of the zone closest to current price and it is where the entry goes. The distal is the far edge and the stop goes behind it. Each school draws them differently; pick one and do not change it.
What do RBR and DBR mean?
Rally-base-rally and drop-base-rally. Both are demand zones: price leaves the base to the upside. Their supply equivalents are DBD and RBD.
How many times does a zone hold?
For the classic school, the best one is the fresh zone and, after 3 or more tests, it is considered broken. A study on supports and resistances found the opposite: more previous bounces, higher probability of a bounce. There is no consensus.
How is a supply and demand zone different from an order block?
The order block is the last opposing candle before an impulse and it requires a structure break. The zone is the whole base and does not need that break. The order block is narrower; the zone, wider.
Does supply and demand work?
Levels react slightly more than chance (60.8% versus 56.2% in Osler's study), but nobody has proven that the base-plus-departure method is profitable on futures after costs.
