ICT vs Supply and Demand Trading: Zones, Liquidity and Timing

Traders who move from supply and demand to ICT, or the other way, often notice that the two approaches seem to point at the same places on the chart. That is partly true. Both look for the origin of strong moves and expect price to react when it returns. But they draw their zones differently, they ask different questions about context, and ICT puts particular weight on liquidity and time. This lesson compares the two neutrally, so you can decide what to borrow from each.

What it is

Supply and demand in brief

A supply and demand trader looks for a base: a short cluster of small candles where price paused before leaving strongly. Four patterns are common:

• Drop-base-rally (DBR): a fall, a base, then a rally. The base is a demand zone.
• Rally-base-rally (RBR): a continuation demand zone.
• Rally-base-drop (RBD): a rally, a base, then a drop. The base is a supply zone.
• Drop-base-drop (DBD): a continuation supply zone.

The zone has a proximal line (the edge nearest current price, often the highest body in a demand base) and a distal line (the far edge, usually the most extreme wick). Traders grade zones by the strength of the departure, how long price stayed in the base, and freshness: whether price has returned to the zone yet. Many treat the first return as the strongest.

ICT in brief

ICT looks at the same kind of move but marks it with different tools. The order block is the last opposite-colored candle before the displacement. The fair value gap is the one-sided range the displacement left behind. ICT traders then add two layers of context: which liquidity was taken before the move, and whether it happened in a meaningful time window.

How the two compare

Both sides contain many educators with their own variations, so any comparison is a generalization.

How to identify each on the same move

1. Find a strong departure from an area, with large candles leaving it.
2. Supply and demand: mark the base candles, draw the proximal line at the base's nearest body edge and the distal line at its extreme wick.
3. ICT: mark the last opposite-colored candle inside that area as the order block, and any FVG in the departure.
4. Check liquidity: did the move first take a prior low (for demand) or high (for supply)? ICT traders give this a lot of weight.
5. Check time: did the move start in a kill zone or near a session open?
6. Compare entries and stops from each method before deciding which you trust.

Worked example: one EUR/USD move, two readings

All prices are illustrative. Assume a 1-hour EUR/USD chart.

• Price drops from 1.0890 toward a prior swing low at 1.0842.
• A base of three small candles forms. Their bodies sit between 1.0843 and 1.0850, and the lowest wick reaches 1.0838, briefly trading below 1.0842.
• The last of those candles is a down-close candle: open 1.0849, close 1.0843, high 1.0851, low 1.0838.
• Price then rallies hard during the London kill zone, breaking a lower high at 1.0880 and reaching 1.0920. The rally leaves a bullish FVG between 1.0856 and 1.0868 (50% at 1.0862).

Supply and demand reading: a drop-base-rally demand zone with the proximal line at 1.0850 and the distal line at 1.0838. Entry on the first return at 1.0850, stop at 1.0835 (3 pips below the distal line).

ICT reading: the base wick swept sell-side liquidity below 1.0842, the rally broke structure, and it began in a kill zone. The down-close candle is a bullish order block (1.0838–1.0851) and the rally left an FVG. One common entry is the FVG's 50% level at 1.0862, with the stop below the order block at 1.0835.

The zones overlap, and both use almost the same invalidation. The difference is where each approach expects price to react. The deeper supply and demand entry offers more reward per pip of risk but is filled less often, because price may turn at the FVG and never reach the base. The ICT reading also gives a reason to prefer this zone over others nearby: the sweep and the timing. With a $10,000 account risking 1% ($100), the sizes would be about 0.67 lots and 0.37 lots respectively, at roughly $10 per pip per standard lot.

How traders use it

• Blending. Some traders draw supply and demand zones for location, then use an ICT liquidity sweep and a kill zone as filters for timing.
• Borrowing freshness. ICT traders sometimes adopt the idea that a zone's first retest deserves more attention than later ones.
• Choosing one rulebook. Many find it simplest to commit to one approach and use the other only as a cross-check.

Trading carries substantial risk of loss, whichever framework you use. Zones are areas of interest, not guarantees, so size every trade from the stop distance.

Common mistakes

• Assuming different names mean different levels. Often the same area is being described in two vocabularies.
• Assuming the same area means the same trade. Entries, stops and filters can differ a lot.
• Mixing rules mid-trade, such as entering at an FVG and placing a stop at a proximal line.
• Ignoring context in either method. A demand zone against a strong higher-timeframe downtrend is weaker in both frameworks.
• Arguing which is "better" instead of testing your own rules.

Summary

Supply and demand draws zones from the base before a strong move, using proximal and distal lines and grading by departure and freshness. ICT marks the same moves with order blocks and fair value gaps and adds explicit attention to liquidity sweeps and time windows. They often agree on location and differ on boundaries, entries and filters. Neither is proven better; test the rules you prefer and manage risk on every trade.
