Bullish Order Block: How It's Defined and How Sources Differ

What Is a Bullish Order Block?

Descriptions of a "bullish order block" vary depending on which trading-education source you read, and the two main descriptions gathered for this guide describe somewhat different things.

LuxAlgo's guide to finding order blocks describes order blocks generally as zones on a chart where institutional buying or selling activity is thought to have occurred. In the bullish case specifically, LuxAlgo notes these zones often appear as a bearish-coloured candle that forms just before price moves upward, acting as potential support. That's a formation-based description: a specific candle pattern, tied by LuxAlgo to an inference about institutional activity.

Alchemy Markets' explainer describes a bullish order block more broadly, as a support zone that sits below the current price — a positional description that doesn't require identifying any particular candle shape. Alchemy Markets frames it as functioning like any other order block: acting as support while price trades above it, with the possibility of flipping to resistance if price later breaks back through the zone, and vice versa.

These aren't identical claims: LuxAlgo's description centers on a specific candle formation, while Alchemy Markets' description centers on a broader support-zone concept, and the two sources don't describe the same thing. It's also worth noting that tying a candle's shape to actual institutional order flow, as LuxAlgo's description does, is an inference about market participants — the material gathered for this guide doesn't include published order-flow data to verify that attribution.

How Traders Identify a Bullish Order Block

No single formula is universal across the sources gathered for this guide, and the identification cues below come from different publishers rather than one combined rule:

• Candle appearance. LuxAlgo notes these zones often appear as a bearish-coloured candle immediately before price moves upward, rather than an up-close candle.
• Wick proportion. Separately, Alchemy Markets suggests looking for a candle where the wick makes up roughly 40% of the candle's total range, as its own rule of thumb for narrowing down candidate zones. This isn't a rule that appears in the LuxAlgo excerpt gathered for this guide, and the two publishers' cues shouldn't be read as one combined test.
• Timeframe weight. LuxAlgo's guide, published August 8, 2025, points toward focusing on higher timeframes such as the 4-hour or daily chart when looking for stronger order blocks, rather than lower ones.

Because none of these is a strict, universally agreed-on definition, different sources can end up marking slightly different candles as "the" order block on the same chart.

A Labelled Mirror-Image Example: The Bearish Order Block

FluxCharts' breakdown of order blocks walks through one specific example on the bearish side: price retraces up to a bearish order block, respects it, and is then followed by a bearish 9/21 EMA crossover — described by that source as a common bearish reversal signal. This is a single illustrated example from one source about the bearish (mirror-image) case, not a finding about bullish order blocks — it's included here only because it's the opposite-direction version of the same concept.

How a Bullish Order Block Is Described as Being Traded

A tutorial published at innercircletrader.net — treated here as that URL's own tutorial content, not verified official Inner Circle Trader material — describes bullish order blocks as behaving differently depending on the broader trend. It states that in a bearish trend, a bullish order block may only produce a small retracement move, and frames the setup as working better within an existing bullish trend.

The same tutorial raises seeking additional confirmation from a lower-timeframe shift in market structure as a general idea before treating a zone as significant. This article deliberately doesn't repeat any specific entry level, retracement percentage, or named trigger timeframe from that tutorial — the point carried over here is that the concept of seeking further confirmation exists in that material, not a set of steps to follow. Nothing in this article is an instruction to enter, exit, or size any trade; see the disclosure below.

What Kind of Sources This Article Draws On

The descriptions gathered for this guide come from a handful of commercial trading-education publishers and one independently-run tutorial site, not from independent, peer-reviewed research into whether order blocks work as described.

Reliability claims for chart patterns like this are hard to verify from published material generally: a stated win rate depends on how "success" is defined, what sample of trades and time period it's drawn from, and whether the test was run independently of whoever is publishing it. CrossTrade's order block guide itself cautions that marketing-promoted win-rate figures for order blocks are typically cherry-picked and not representative — a caution about that category of claim, not a rate this article is putting forward as accurate. No dated, methodologically transparent study of order block reliability appears in the material gathered for this piece.

CrossTrade's guide does state that real order block trading requires patience and confluence with higher-timeframe context, and frames ICT (Inner Circle Trader) as a broader trading methodology that includes order blocks as one of its core concepts, alongside fair value gaps, liquidity sweeps, and other Smart Money Concepts ideas.

What the sources above describe, and where their descriptions diverge:

Comparing How Sources Define and Use the Term

Since no single formula is universal, it helps to see what each source actually says, and doesn't say:

• LuxAlgo describes a bullish order block as a zone tied to inferred institutional buying, visually flagged by a bearish-coloured candle right before an upward move, and frames it as a stronger signal on higher timeframes. The excerpt gathered from LuxAlgo's guide for this piece doesn't include a dated test of how often that visual cue is followed by the described move.
• Alchemy Markets describes a bullish order block more broadly, as a support zone below current price that behaves like ordinary support/resistance, plus a separate candle-wick heuristic for narrowing candidates. Alchemy Markets doesn't tie its wick rule to LuxAlgo's bearish-candle cue — these are two publishers' separate heuristics, not one combined rule.
• The tutorial at innercircletrader.net frames bullish order blocks as more effective within an existing bullish trend and raises seeking lower-timeframe confirmation as a general idea; the material gathered from that tutorial doesn't include a stated outcome rate for that approach.
• CrossTrade situates order blocks inside a wider ICT/SMC toolkit and explicitly cautions that marketing-promoted win-rate claims for the pattern are typically cherry-picked.
• FluxCharts shows one labelled example of the mirror-image bearish order block being respected, paired with a moving-average crossover signal — a single illustrated instance, not a rate or study.

What none of these sources provides, in the material gathered here, is an independent, dated backtest of how often a bullish order block, by any of these descriptions, is actually followed by the price move it's associated with.

Where This Fits in a Broader Smart Money Concept Toolkit

A bullish order block rarely sits in isolation within ICT/SMC-style analysis. CrossTrade's guide groups it alongside fair value gaps and liquidity sweeps as core concepts within the same methodology. Readers looking at related concepts may also want to review how liquidity grabs and liquidity sweeps are defined, how the smart money concept liquidity sweep idea relates to order blocks, and how position sizing and risk management are approached more generally in forex trading.
