Order BlockOB
An order block is usually described as the last opposite-direction candle before a strong move, treated as a zone where large orders may have been placed.
An order block is a Smart Money Concepts (SMC) term for a price zone where large players may have placed big orders. Traders usually mark it as the last opposite candle before a strong move, and watch whether price reacts when it returns. It is a theory and is only clear in hindsight.

Order block in plain words
In smart-money-concepts language, an order block is a price zone where big institutional orders may have been placed.1
It is usually marked as the last down candle before a sharp rally, or the last up candle before a sharp drop.1
A real block is followed by a fast, one-way move that breaks structure or runs through obvious highs or lows.2
How traders mark an order block
Find a strong move
Look for a fast, one-sided move.
Find the last opposite candle
For a bullish block, mark the last down candle (or small group) before a sharp rise.2
Check the follow-through
Confirm it with the move that followed: fast, one-directional and breaking structure.2
Mark the zone
Use the candle's high and low as the zone.
Wait for a return
Expect some blocks to produce no reaction at all.1
Watch the calendar
Be careful around central-bank news, which can blow through even a clean block.2
Worked examples
Example 1 — Bullish block
Zone markedHypothetical: last red candle 1.3000–1.3020, then a rally to 1.3150.
| Zone | 1.3000–1.3020 |
| Rally | +130 pips |
The zone is the last down candle before the strong rally.1
Example 2 — Reaction
+75 pipsHypothetical long at 1.3015, stop 1.2990, exit 1.3090.
| Risk | 25 pips |
| Result | +75 pips |
Price reacted here, but order blocks are identified retrospectively, so this was not knowable in advance.1
Example 3 — No reaction
−25 pipsHypothetical: price cuts through the zone on a rate decision.
| Entry | 1.3015 |
| Stop | 1.2990 |
The rate decision blew straight through the block.2
