Support & Resistance
vs
Supply & Demand
— Which One Are You
Actually Trading?
Most synthetic indices traders use these two concepts as if they mean the same thing. They do not. This guide draws the hard line between them, shows exactly how each one behaves on V75, Boom/Crash, and Step Index — and builds the unified framework that actually holds up under real market conditions.
Every serious synthetic indices trader eventually lands on the same two concepts: Support and Resistance, and Supply and Demand. They look similar on a chart. They're both about price reacting at levels. They're referenced in the same breath by most trading educators. And yet, if you dig into how each one is identified, why each one works, and how each one fails — they are fundamentally different frameworks built on entirely different logic.
Getting this distinction wrong costs traders real money. The trader who marks a round-number horizontal line and calls it a supply zone has already made a category error. The trader who draws neat rectangles around every consolidation and calls it support has made a different but equally costly mistake. Both end up confused when their "zones" don't hold, wondering why the market keeps running through what looked like obvious structure.
This article builds the complete picture from scratch. What Support and Resistance actually is. What Supply and Demand actually is. Where they overlap, where they diverge, and — critically — how each one performs on the specific instruments you're trading on Deriv. By the end, you will have a clear, unified framework that tells you exactly which concept to lean on in any given context on synthetic indices.

The Core Definitions — What They Actually Mean
The fundamental difference is this: Support and Resistance is a statistical observation — price has bounced at this level before, therefore it may bounce again. Supply and Demand is a structural argument — price left this area rapidly because there was an imbalance of orders, and when price returns, those unfilled orders will cause another reaction.
One says "this has happened here before." The other says "this is why it happened — and why it will happen again." That distinction sounds subtle in theory. In practice, it changes where you draw your level, how wide it is, how you enter a trade against it, and what invalidates it.
Ask yourself this when you mark a level: "Am I drawing this because price bounced here before — or because I can see where price came from before a strong move?" The first answer is Support and Resistance. The second is Supply and Demand. Both can be valid. They just operate on different logic and must be traded differently.
Why They Work — The Logic Behind Each Method
Before applying either concept to synthetic indices, you need to understand why they produce reactions at all — because the "why" tells you exactly when to trust a level and when to question it.
Why Support and Resistance Works
Support and Resistance works because of collective memory and market psychology. When a large number of traders see the same historical level, they cluster their orders around it. Buyers who missed the last bounce from support set new limit orders at the same price. Sellers who profited at resistance set new short entries at the same price. Traders who held through a break-back to the level now have their stop losses sitting right there.
The result is a self-reinforcing concentration of orders at a visible price level — which creates a reaction when price returns. It is, fundamentally, a crowd psychology effect. The level holds because enough participants believe it will hold and act accordingly.
Price approaches a historical level → traders with limit orders placed there participate → orders absorb selling/buying pressure → price reacts. The reaction is crowd-driven. The level is valid as long as participants are watching it.
Price returns to a zone where it previously departed rapidly → the unfilled portion of the original order cluster re-engages → imbalance triggers another directional move. The reaction is structural. The zone is valid until those orders are filled or cancelled.
Why Supply and Demand Works
Supply and Demand works because of order flow imbalance. When price moves away from an area sharply — in one or two strong candles — it means there was a large, unfilled order block in that area. The buyers or sellers who placed those orders did not have enough counterparty volume to get fully filled before price moved. Their remaining orders sit unfilled at those price levels.
When price returns to that zone, those unfilled orders re-engage. This is not a psychological effect — it is a structural one. The zone holds because actual orders that originated the first move are still present and waiting.
Support and Resistance tells you where price has been. Supply and Demand tells you why it left — and why it will react when it comes back.
— Core distinction in order-flow based trading methodologyHow This Applies to Synthetic Indices Specifically
On instruments like Volatility 75 or Boom and Crash indices, the "institutional order" argument for Supply and Demand requires a slight reframe. There are no banks placing block orders on V75. The price is algorithmically generated. So why does Supply and Demand still work on these instruments?
Because the algorithm itself generates statistically consistent behaviour that mimics order-flow patterns. When V75 produces a sharp impulse move away from a base, that base remains algorithmically "loaded" — meaning when price returns to that area, the same statistical pressures that produced the original move tend to reproduce a similar reaction. The concept holds not because of actual institutional orders, but because of the structural properties of the price generation algorithm.
On Deriv's synthetic instruments, Supply and Demand zones work because the algorithm generates statistically repeatable behaviour from the same price origins. You do not need institutional order flow to explain it. The mechanics produce the same outcome: a zone defined by an impulse origin reliably re-triggers directional behaviour when revisited — on V75, Boom and Crash, Step Index, and across the range of synthetic instruments.
How to Identify Each on a Synthetic Index Chart
How to Identify Support and Resistance
Look for historical touches: Find price levels where the market has reversed or paused at least twice. Two touches makes a line. Three or more touches makes a strong line. The more times price has respected the level, the more significant it is.
Mark it as a horizontal line: S&R is always horizontal. It is a specific price. Not a range, not a zone — a line. On synthetic indices, round numbers (for example, 600,000 on V75) often function as additional psychological S&R levels that reinforce technical ones.
Apply the role-reversal rule: When a resistance level is decisively broken, it becomes support. When a support level is broken, it becomes resistance. This flip is one of the most reliable confirmations of a trend continuation trade entry on any synthetic index.
Use the right timeframe: Daily and H4 S&R levels carry the most weight. M15 and M5 levels are useful for entry precision but should be traded in the direction of the higher timeframe bias. Never trade a lower-timeframe S&R level against a higher-timeframe trend.
How to Identify Supply and Demand Zones
Find the base of an impulsive move: Look for a sharp, strong candle (or sequence of 2–3 candles) that moved decisively in one direction. Work backward from that impulse to find the consolidation base immediately before it. That base is the zone.
Draw a rectangle around the base candles: The zone spans from the lowest low to the highest high of the base candles — the consolidation before the impulse. On V75, this zone is often 15–40 pips wide. On Boom and Crash, zones tend to be wider due to the spike mechanics.
Assess freshness: A zone is "fresh" if price has not returned to it since the impulse originated. Fresh zones produce the strongest reactions. Once price returns and trades through a zone, the unfilled orders are considered filled and the zone loses most of its significance.
Check the departure speed: The faster and stronger the departure from the base, the more significant the zone. A single large candle departure is more significant than a gradual drift away from the area. On V75, look for moves that cover 100+ pips in 1–2 candles on the M15 as your highest-quality zone origins.
The most frequent mistake traders make is drawing a Supply and Demand zone at every consolidation area regardless of whether a strong impulse followed. A base without a subsequent impulse is just a range — not a Supply or Demand zone. The impulse departure is what makes the zone valid. No impulse, no zone.
Head-to-Head: Performance on Synthetic Indices
Both frameworks have been applied extensively on synthetic indices. Here is how they compare across the dimensions that actually matter for a trader operating on V75, Boom/Crash, and related instruments.
The data points toward Supply and Demand producing higher-quality trades when correctly identified on synthetic indices — particularly because zones give defined boundaries for stop placement, which solves one of the core challenges on a high-volatility instrument like V75.
However, Support and Resistance retains a significant practical edge: it is faster to identify in real time, integrates cleanly with indicator-based context reads (such as EMA position and RSI), and remains very reliable at the higher timeframes where most traders operate for their directional bias.
The real answer, as always with synthetic indices, is that you need both — operating in different roles.
Per-Instrument Breakdown — V75, Boom/Crash, Step Index
Not all synthetic instruments behave the same way — and the relative effectiveness of S&R vs Supply and Demand shifts depending on which instrument you are trading. Here is the breakdown for the three most actively traded synthetics on Deriv.
S&R: Works reliably at H4 and D1 timeframes. Round-number levels add extra confluence. The role-reversal (broken resistance becoming support) is one of the cleanest, most reliable trades on V75.
S&D: Very strong on V75 — especially fresh demand zones on H1 and M15. The key adaptation: always allow for the wick sweep below the zone before the reaction (add 10–15 pip buffer to stop). The stronger the original departure, the more reliable the zone on return.
S&R: Moderate reliability. The spike mechanic on Boom/Crash creates artificial levels that get swept regularly. Horizontal S&R lines placed at spike highs are frequently false levels — those spikes are the instrument's mechanics, not market structure.
S&D: Significantly more effective on Boom/Crash than S&R. Supply zones before spike drops, and demand zones before spike rises, give you the structural context that horizontal lines cannot. Mark the base before each major spike — those zones are your highest-value levels on this instrument.
S&R: Works very well on Step Index due to its lower volatility and more measured price movement. Horizontal levels at swing highs and lows hold cleanly, and the role-reversal trade is especially clean here.
S&D: Also effective, but zones tend to be narrower given Step Index's smaller candle range. Fresh demand zones after directional moves give precise entry opportunities with very tight stops relative to the move size — making Step Index supply/demand trades some of the best R:R setups in the synthetic range.
On Boom 1000 and Crash 1000, do not mark S&R resistance at the high of a spike candle. That spike is the instrument's built-in mechanic — not a structural level created by market participants. Marking resistance at spike highs will produce an endless series of false setups as subsequent spikes pierce those levels routinely. Mark your levels at the base of the spike origin area, not the spike tip itself.
When They Fail — And How to Know in Advance
When Support and Resistance Fails
Strong momentum breaks: When price approaches an S&R level with strong momentum — large candle bodies, little wicking, no slowdown — the probability of a break is high. On synthetic indices, where strong trend legs can cover 300+ pips without a meaningful pause, S&R levels on lower timeframes are highly vulnerable to being steamrolled during trend legs.
Overuse and overmarking: A chart covered in horizontal lines creates false certainty. Every level you mark reduces the signal-to-noise ratio of the genuine ones. Restrict S&R marking to levels with a minimum of three clean touches on the H4 chart. Everything else is noise.
Trending markets on synthetic indices: V75 and Boom 1000 can sustain extended, uninterrupted trends. In a strong trend, even well-respected S&R levels from the past will break. The trend context must always dominate. Never trade against a confirmed trend just because an old S&R level is in the path.
When Supply and Demand Zones Fail
Stale zones (already tested): The most common cause of Supply and Demand failure. A zone that has already been returned to and traded through has had its orders absorbed. It is no longer a valid unfilled order cluster. Mark it as consumed and stop trading it. Fresh zones only.
Weak departure strength: If the departure from the zone origin was gradual rather than impulsive, the zone's validity is questionable. The speed and strength of the departure is the evidence of the order imbalance. A slow drift away does not leave significant unfilled orders behind — therefore returning to that area lacks a structural reason to reverse.
Against a dominant higher-timeframe trend: Just like S&R, Supply and Demand zones on lower timeframes that sit against the higher-timeframe trend are lower-probability. A demand zone on M15 during a D1 downtrend may produce a brief bounce — but the dominant selling pressure will typically push through it. Use zones in the direction of the higher-timeframe structure bias.
For both S&R and Supply and Demand: if price approaches your level with three or more consecutive strong candles in the same direction, with minimal wicking and no consolidation, that is momentum. Momentum typically wins. Do not position against it regardless of how clean your level looks. Wait for momentum to slow — a small base or consolidation near the level — before considering an entry against the move.
The Unified Framework — How to Use Both Together
The unified framework is not a compromise between two methods — it is the recognition that each method answers a different question. When you stop asking "which one is better" and start asking "which one answers which question," the integration becomes natural.
→ Where are the major S/R levels on the H4 and D1 chart?
→ Is price in an uptrend (HH/HL) or downtrend (LH/LL)?
→ Has a major resistance level been broken and flipped to support?
→ Output: BULLISH BIAS or BEARISH BIAS
STEP 2 — ZONE SELECTION (Supply & Demand, H1 or M15)
→ In the direction of Step 1, where is the nearest fresh S/D zone?
→ Does the S/D zone align with an S/R level from Step 1? (Confluence)
→ Is the zone truly fresh — not yet returned to since formation?
→ Output: ZONE IDENTIFIED (entry area defined)
STEP 3 — ENTRY AND TARGET (Price Action at Zone / S/R for Target)
→ Wait for confirmation candle at zone boundary (closed candle only)
→ Stop: below zone low + 10–15 pip V75 buffer (or zone-specific buffer)
→ Target: next significant S/R level in bias direction
→ R:R check: if ≥ 1:2, ENTER. If below 1:2, SKIP.
Notice how each concept does exactly one job. S&R never tells you where to enter. Supply and Demand never tells you the overall direction. Price action never defines the target. The separation is total — and that prevents the confusion that comes from trying to make one tool do everything.
The highest-probability setups on synthetic indices occur when a Supply and Demand zone aligns directly with an S&R level from a higher timeframe. When your M15 demand zone sits on top of an H4 support level that has been tested three times — you have two independent structural reasons for a reaction at the same location. That confluence meaningfully increases the probability of a clean trade. Always look for it before entering.
Three Practical Setups Using the Combined Approach
The framework becomes real when it produces executable trades. Here are three setups that apply the unified model in specific, actionable ways — each of which can be traded on V75 and adapted for Boom/Crash and Step Index.
Setup 1 — The Confluence Stack (Highest Probability)
This is the setup where a Supply or Demand zone aligns with a confirmed S&R level. It is the highest-probability setup in the unified framework and should be the primary focus for any trader combining both methods.
Identify on H4: Mark all key S/R levels on H4. Identify the current trend direction (HH/HL for bullish, LH/LL for bearish). Look for an S/R level that is about to be re-tested from the correct side — support being re-tested from above in an uptrend.
Locate the Demand Zone on H1: Drop to H1 and find the fresh demand zone in the area of the H4 S/R support level. If the demand zone's lower boundary is within 15–20 pips of the H4 S/R support, you have a confluence stack.
Execute on M15: Wait for price to enter the demand zone. A wick below the zone lower boundary followed by a strong bullish candle closing back inside is the entry trigger. Stop below the confluence area with buffer. Target: next H4 resistance level.
Setup 2 — The Role-Reversal Demand Zone (Trend Continuation)
When an S&R resistance level is broken and flips to support, the area where price broke through becomes a natural demand zone origin. This setup captures the first clean pullback to that newly-formed support area using Supply and Demand zone logic to define the entry.
Confirm the break: On H1, identify a clear break of a resistance level — a full candle close above it with momentum, not just a wick. The broken resistance now becomes the support to watch.
Mark the breakout candle as the zone: The base of the breakout candle (or the last consolidation before the breakout candle) is your demand zone. This is where price departed from when it broke resistance — those are your unfilled continuation orders.
Enter on the pullback: When price pulls back into the demand zone and produces a confirmation candle, enter in the direction of the break. This is a trend continuation entry with a structural stop (below the demand zone) and a clear target (extension of the breakout move).
Setup 3 — The Untouched Zone at Major S/R Boundary (Premium Setup)
The most premium version of the combined framework: a Supply or Demand zone at a major S/R level that has never been re-tested since formation. These setups are rarer but produce the cleanest, largest moves on synthetic indices.
Locate a D1 or H4 S/R level with 3+ touches: This is a major level with strong collective memory behind it. Mark it clearly. Then identify whether there is an untouched (fresh) Supply or Demand zone sitting within 10 pips of that level.
Wait for the approach: Do nothing until price approaches the combined area. You are not predicting — you are waiting for the market to come to you. On V75, this patience discipline separates profitable traders from accounts that bleed slowly from premature entries.
Execute with full size on the confirmation candle: When price enters the zone and produces a strong confirmation candle, this is one of the highest-conviction setups available on synthetic indices. Target the next major S/R level two or three structures away. Minimum R:R 1:3 on this setup due to the quality of the location.
These three setups are not everyday occurrences on a single instrument. Setup 1 and 2 appear multiple times per week on V75 across timeframes. Setup 3 is a once-or-twice-per-week event at most. The discipline is to only take the setups when all criteria are met — and to do nothing when they are not. Overtrading against incomplete setups is the primary cause of drawdowns on synthetic indices, not bad strategy.
