ICT Hidden Order Block Explained

What is Hidden Order Block in ICT?

A less universally standardized label for an order-block-like reference that is not the obvious final opposing candle or is nested within a larger structure.

Definition of Hidden Order Block

An OB identified through a particular educator's refinement rule; there is no single universally accepted definition.

How to identify Hidden Order Block

Apply the exact source-specific selection rule; record timeframe, candle boundaries and the structural event that validates it.

Bullish Hidden Order Block example

a smaller hidden bullish block within a larger up-leg supports a retracement.

Bearish Hidden Order Block example

a nested bearish block caps a rally.

Hidden Order Block chart examples

Practical trading example

On a 1-minute chart inside a 15-minute bullish OB, a smaller candle cluster precedes a micro break; it may be marked only if the chosen method defines it.

Common mistakes and important notes

Treat as advanced/source-dependent terminology. Do not label any small candle inside an OB as hidden OB without rules.
