The idea, popular in smart money concepts (SMC), is that large participants built positions in that zone before the impulsive move and may defend it. A bullish order block is the last down candle before a strong rally that breaks a prior high; a bearish one is the last up candle before a sharp drop. Traders mark the candle's range and look for entries when price returns to it.
Example
BTC prints a red four-hour candle from $59,800 down to $59,200, then rallies to $62,500, breaking the previous swing high at $61,000. A trader marks $59,200–$59,800 as a bullish order block, places a buy limit at $59,750 with a stop at $59,050 and targets the new high at $62,500. Risk is $700 and reward $2,750, about 3.9R.
Why it matters
Order blocks give precise zones, based on structure, for entries with tight stops, which can produce large R-multiples. As with any concept, the value comes from testing specific rules for which blocks count.
Common mistake
Marking every candle before a move as an order block. Without clear rules, such as a break of structure, a zone not yet revisited or a fair value gap left behind, almost any zone fits after the fact. Write the rules down and track them in your journal.
FAQ
- What makes a valid order block?
- Definitions vary, but common conditions are a strong impulsive move away from the zone, a break of market structure and the zone not having been revisited yet.
- Is an order block the same as support and resistance?
- They overlap. An order block is a specific zone tied to where an impulsive move started; support and resistance are broader areas of repeated reactions.
- What is a mitigated order block?
- One that price has already returned to. Many traders consider a block weaker, or used up, after the first revisit.
