Why Your Supply and Demand Zones All Look the Same on TradingView

by ZynAlgoAugust 6, 20267 min read

The problem with equal-weight zones

You have five demand rectangles stacked across your 15-minute chart, price is dropping into the cluster, and not one of them tells you which zone actually matters. They were all drawn the same way, three bars in a row, a pivot, a box, so they all look equally important. By the time you pick one and set your limit order, you are guessing.

The real difference between zones is participation: how much volume built the level in the first place. A zone formed on three quiet bars during lunch and a zone formed on three bars of genuine directional flow deserve different amounts of attention. Core Supply & Demand TDV ranks every zone by the net directional volume that created it, so the ones worth watching are already marked before you have to choose.

What it does

Core Supply & Demand is a TradingView indicator that identifies supply and demand zones, compares the volume accumulated across the bars that formed each one, and prints a small set of ranked rectangles instead of cluttering the chart with equal-looking boxes.

Every zone starts the same way: three consecutive bars moving in the same direction. That sequence is checked against the running average of recent volume. If participation is below average, no zone is drawn. If it clears that threshold, the indicator calculates the net directional volume across those bars, positive for demand, negative for supply, and assigns that figure as the zone's score.

The zone boundary is set using long-term ATR, so the thickness adapts to the instrument's actual volatility. Once drawn, the zone stays on the chart until price closes through it or until it drops off the five-zone-per-side limit.

Each rectangle carries a label at its right edge showing two numbers:

  • Vol, the net volume figure for that zone.
  • Power, the same number expressed on a 1-to-10 scale by comparing it against every other zone currently tracked.

A zone with Power 8.5 holds a much larger share of the directional flow on your chart than a zone scoring 1.2. That difference is the entire point: it tells you where the heavier participation sits without forcing you to eyeball overlapping boxes.

A small panel in the lower right corner lists the most recent readings for both supply and demand, so you can see at a glance which side is carrying more weight.

How it is used in a session

You load the indicator on a volume-bearing market, futures, indices, crypto, and let it populate the chart. Within a few bars you will see a handful of zones, each labeled with its Vol and Power score.

Step one: check the zone state. A solid border means fresh; price has not yet returned. A dashed border means mitigated; price has already wicked into the zone and part of the resting volume has been absorbed. Fresh zones with higher Power scores are the ones worth watching for a reaction.

Step two: wait for a rejection close, not just a touch. The indicator prints a diamond marker when three conditions line up on the same bar:

  • Price penetrates the zone boundary (low into demand, high into supply).
  • The bar closes back outside that boundary in the matching direction: bullish close above the demand zone top for a Zyn Buy, bearish close below the supply zone bottom for a Zyn Sell.
  • The spacing filter (Signal Coolbar, default 10 bars) has been satisfied since the last marker in that direction.

That rejection close is the event you trade around. A limit order resting inside the zone gets filled whether or not the zone holds; the close outside the boundary is a stricter trigger.

Step three: compare both sides. The panel shows whether supply and demand agree with the direction you are considering. If you are watching for a bounce off demand but the supply-side Power readings are heavier, the chart is telling you something.

Step four: set your invalidation. A zone is removed when a bar closes through it. That natural boundary is where your stop belongs.

On fast intraday charts, raise Signal Coolbar to avoid a stream of markers during one sideways grind. On higher timeframes, the default spacing is usually enough.

Who it fits

This tool is built for supply and demand traders who are tired of treating every level as equal. If you have been setting limit orders inside zones and getting filled on the ones that fail, the rejection-close logic gives you a stricter entry condition.

It suits intraday and swing traders working volume-bearing instruments. Spot FX feeds tick volume, so the score there is a rough proxy rather than a precise measure.

It is a context and mapping tool, not a standalone system. Settings are deliberately short, two zone colors and one spacing filter, so there is nothing to curve-fit. The indicator assumes you already have a trade plan and position-sizing rules; it supplies ranked levels and rejection markers to support that plan.

What it does not do

Core Supply & Demand does not predict which zones will hold. The Power score tells you how much volume built the zone; it does not tell you what price will do when it gets there. A high-ranking zone can still fail if the opposing flow is heavier or if the larger market context has shifted.

It does not replace discretion. Price grinding along a zone edge, a gap through the level, or a fundamental event mid-session can all make the ranked score less relevant. The tool narrows the field; you still decide whether the setup fits your plan.

It is not well suited to markets with unreliable volume data or to traders who prefer geometric levels like round numbers and Fibonacci extensions. If your method does not involve supply and demand concepts, ranking zones by participation will not add value.

The rejection-close logic is stricter than a simple touch, which means fewer signals. If you need a high frequency of entries, this is the wrong filter.

Pairing with other tools

Core Supply & Demand maps where participation built levels; it does not tell you the broader trend or regime. Pairing it with Context TDV gives you multi-timeframe trend alignment so you can favor demand zones in an uptrend and supply zones in a downtrend, rather than trading every rejection blindly.

If you work with order-flow concepts beyond simple zones, Micro-Profile TDV adds a volume-profile view inside the same TradingView chart, showing you where the heaviest traded volume sits within the price range. Used together, you can see whether a high-Power demand zone also lines up with a volume node, which adds another layer of confluence.

Do not combine Core Supply & Demand with another zone-drawing indicator that uses a different ranking method. You will end up with two sets of boxes that contradict each other.

Trading involves risk

Core Supply & Demand is an analysis tool. It does not place trades, it cannot know what price will do next, and no indicator removes market risk. The Power score reflects past participation, not future behavior. Always trade with your own plan, position sizing, and risk management. Nothing here is investment advice.
