Support and resistance zones explained
By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.
Quick answer
Support and resistance zones are price ranges where buyers or sellers have historically stepped in with size, causing reversals or pauses. Unlike single horizontal lines, zones acknowledge that orders cluster across a band of prices, reflecting how institutional participants accumulate or distribute positions over time rather than at one exact tick.
What is support resistance zones?
A support zone is a price band where buying interest has previously outweighed selling pressure, halting declines and often triggering reversals. A resistance zone is the inverse: a band where sellers have consistently absorbed bids and capped advances. The desk treats these as ranges rather than precise lines because real order flow rarely concentrates at a single price. Zones are typically drawn using prior swing highs and lows, consolidation areas, and the wicks plus bodies of significant candles. They lose validity once decisively broken on closing basis with follow-through volume.
How traders use support resistance zones
Retail traders mark zones on higher timeframes, usually the daily and four-hour, then refine entries on lower timeframes when price tests these areas. The desk observes that practical use involves waiting for confirmation, such as a rejection wick, a shift in lower-timeframe structure, or a volume spike, rather than committing the moment price touches a zone. Institutional desks tend to scale orders across a zone because filling large size at a single price is impractical and would move the market against them. Stops are commonly placed beyond the far side of the zone to account for liquidity sweeps. Zones are also used to anchor risk-reward calculations and to identify where breakout traders may step in if the band fails.
Common misconceptions about support and resistance zones
The first misconception is that zones are precise lines. Drawing a single pixel-thin line invites frustration when price overshoots by a few pips and then reverses. The second is that older zones are always weaker; in fact, untested zones from prior accumulation phases often hold strongly when revisited. The third is treating every prior high or low as meaningful. The desk reserves attention for zones with clear reaction history, volume confirmation, or confluence with session levels, round numbers, or higher-timeframe structure. Without confluence, a zone is just a guess dressed up as analysis.

Frequently asked
How wide should a support or resistance zone be?
Width depends on the instrument and timeframe. On major FX pairs on a four-hour chart, zones often span ten to thirty pips, reflecting where wicks and bodies cluster around a reaction point. On indices or crypto, zones can be wider in absolute terms. The desk recommends letting price action define the band rather than imposing a fixed width: mark the highest wick and the closing bodies of the reaction candles, and use that range as the zone.
What is the difference between support, resistance, and supply and demand zones?
Support and resistance zones are typically drawn from reaction history at horizontal price levels. Supply and demand zones, popularised by order-flow style traders, focus specifically on the origin of strong impulsive moves, marking the last consolidation before a sharp departure. In practice the two concepts overlap heavily. The desk treats them as complementary rather than competing frameworks: both attempt to identify where unfilled orders likely sit.
Do support and resistance zones work in trending markets?
Yes, but their role shifts. In a trend, broken resistance often becomes support and vice versa, a behaviour known as polarity. Pullbacks to prior breakout zones offer continuation opportunities aligned with the dominant direction. The desk notes that counter-trend trades from zones in strong trends carry lower probability because momentum traders frequently absorb opposing interest. Confluence with trend structure improves outcomes considerably.
How many times can a zone be tested before it breaks?
There is no fixed number. Some zones hold once and never return; others survive multiple tests. What matters is how price reacts at each test. Weakening rejections, smaller bounces, and rising volume on tests usually precede a break. The desk watches for compression against a zone, where price coils tightly rather than bouncing cleanly, as an early warning that resting orders are being absorbed.
