ICT Order Blocks Explained: What They Are and How Traders Use Them
An order block is a chart concept used in ICT and related Smart Money Concepts education. Traders generally identify a candle or small area before an impulsive move and study whether price later reacts from that area.
Bullish and bearish order blocks
A bullish order block is commonly associated with the last bearish candle or bearish area before an upward displacement. A bearish order block is commonly associated with the last bullish candle or area before downward displacement. Exact definitions differ across educators.
Context matters
An order block becomes part of a trading idea only when the trader has defined context, such as market structure, liquidity and a directional hypothesis. Marking every opposite-color candle creates too many zones to be useful.
Define invalidation first
Before entry, decide what price action would invalidate the setup. A zone that is continually redefined after price moves against it cannot be tested objectively.
Order blocks and FVGs
Some traders use an order block together with a nearby FVG or displacement leg. Treat these as confluence rules to be tested, not as proof that an institution placed a specific order at that exact candle.
Worked example (hypothetical)
A practical order-block test begins by writing the candle-selection rule before marking charts. For example, define which final opposing candle qualifies, what size or displacement condition follows it, and whether a structure break is required. Record the zone boundaries and invalidation before any revisit. Later, classify the interaction as a reaction, full trade-through or no revisit within the test horizon. This lets you evaluate the chart pattern without claiming that the candle proves a bank placed an order there.
FAQ: Does an order block prove that a bank placed an order there?
No. The candle pattern does not identify participants or show their intent. Order block is a framework label that traders apply using a defined rule; it should not be presented as verified institutional positioning.
FAQ: Do all educators define order blocks the same way?
No. Sources may differ on the qualifying candle, displacement requirements, swing break, zone boundaries and mitigation. Pick a definition and keep it stable during backtesting.
