Order block
The last candle closing against the move, immediately before a break of structure. It fires on the break bar and draws the candle's range as a zone.
What it looks like on a chart
A shaded band over the order block candle's range, extended forward.
Where the definitions disagree
It is not called “the” order block for a reason. Five mutually incompatible published definitions exist — last opposite-close candle, extreme-in-leg, extreme filtered to colour, volume pivot with no structure break, and a consolidation range — plus four zone conventions. Two coders handed the word produce disjoint trade sets. If your indicator marks different bars, that is the definitions differing, not one of you being wrong. It also does not wait for price to return: that would be a second detector.

| M15 | 240 | last opposite-close candle before the break; zone is its FULL RANGE (four conventions exist) | 503 |
| M30 | 240 | last opposite-close candle before the break; zone is its FULL RANGE (four conventions exist) | 257 |
| H1 | 240 | last opposite-close candle before the break; zone is its FULL RANGE (four conventions exist) | 126 |
| H4 | 240 | last opposite-close candle before the break; zone is its FULL RANGE (four conventions exist) | 26 |
| D1 | 240 | last opposite-close candle before the break; zone is its FULL RANGE (four conventions exist) | 3 |
