An order block is the last down-close candle before a strong bullish break of structure (bullish order block), or the last up-close candle before a strong bearish break (bearish order block). Smart-money concepts treat that candle's range as a zone where institutional flow was accumulated before the move, and therefore as a high-quality return-to-zone level.
Variants exist: some traders use only the candle body, others the full high-to-low range, and many filter for order blocks that coincide with an FVG or a liquidity sweep.
Order blocks are a heuristic, not a measurement. They work as well as the underlying market-structure call — get the BOS right and they age well; get it wrong and you are drawing rectangles on noise.
Example
Price prints a swing low at 50,000, a final red candle from 50,300 → 50,050, then rips up through the prior swing high. That red candle (50,050–50,300) is the bullish order block — a buy-the-pullback zone for the next leg up.
