What is an order block in trading?
An order block is the last opposite candle before a strong move. Here is how traders find them, why they can work, and why they mislead so many beginners.
An order block is the last down candle before a strong move up (a bullish order block), or the last up candle before a strong move down (a bearish one). The idea is that large orders were placed there, and some may still be waiting if price returns.
How traders mark them
- Find a strong move that breaks structure, ideally with displacement (big candles, small wicks).
- Go back to the last opposite candle before it started.
- Mark that candle’s range as a zone, and watch for price to return to it.
Why they mislead beginners
Look at any chart afterwards and you will find order blocks that worked. You will also find many more that didn’t. Without a reason for price to be at that zone, and a rule for entry, order blocks become a way to justify trades rather than find them.
How we use the idea
We don’t trade order blocks on their own. Our entries need a reason first: a sweep of the Asia range, then a change of character. The pullback entry after that often lines up with an order block or a fair value gap, which is a bonus, not the reason.
And yes, it’s where our name comes from.
Questions people ask
Do order blocks work?
They can mark useful areas, but on their own they are unreliable because almost every move has one in hindsight. They work best as a refinement of a setup that already has a clear reason.
What is the difference between an order block and a fair value gap?
An order block is a candle (the last opposite one before a strong move). A fair value gap is the space between candles left by a very fast move. They often appear together.
