What is an order block?
An order block is the last opposite-colour candle before a sharp move. In a rally it's the last down candle before price shoots up. In a decline it's the last up candle before the hard selling. The term spread from what's known as smart money concepts (SMC).
The name makes a big claim: that large players left their orders there. You can't see that on a chart. What you can see is simpler: after that candle price left with a move where one side clearly overwhelmed the other. When price comes back, that side may step in again.
So an order block is a narrower version of a supply or demand zone. The difference is that the move is also required to break structure. A down candle in front of a rally that never broke the previous high is just an ordinary candle.
How do you find an order block on a chart?
Look at the sequence. First a wick below a low, a sweep. Then a sharp rise made of long-bodied candles that closes above the last clear high. The order block is the last down candle right before the candles that started that rise.
An example: on EUR/USD M15 the low at 1.0840 gets swept, with price dipping to 1.0832. The last down candle there has a high of 1.0846 and a low of 1.0834. The next three candles carry price to 1.0880, and the last high at 1.0868 breaks with a close at 1.0875. The order block is 1.0834 to 1.0846.
Then price pulls back to 1.0848, just above the zone. That's a moment to pay attention, not an entry. You wait for a candle showing buyers returning, such as one whose lower wick dips into the zone and closes above 1.0850.
The stop comes from the structure. The idea is that buyers will defend the zone; a close below the zone and the sweep wick ends it. The stop goes a little under 1.0832, at 1.0828. From 1.0850 that's 22 pips of risk, your 1R. The first sensible target is the last high at 1.0880.
Try it on a chart
Find where a sharp move started on this chart: the last opposite-colour candle before it is where an order block would be drawn. No box is drawn for you. Look at which way the structure broke, where price sits now relative to that candle, and where a stop could rest.
Your turn: read the chart and make your call.
No sign-up needed. Take a guess; when the chart opens, you'll see why.
The most common order block mistake
Calling every down candle an order block. There is almost always a down candle before a rise. If the move didn't break structure, wasn't sharp, or had no sweep before it, that candle shows you a candle, not a zone.
The second is treating the zone as a guaranteed turn. A box on the chart tells you where to look, not that price will reverse. Leave a resting buy order in the zone and walk away, and you're unprepared on the days it gets sliced through without a reaction. Without context, confirmation and a stop, the zone says nothing on its own.
The third is putting the stop right on the edge. When price returns to an order block it often pushes into it and wicks through the bottom. Squeeze the stop a pip or two below the edge and you get stopped out even on a correct idea. Put it beyond the structure and cut size if the distance grows.
When does an order block not work?
In a sideways market the read is weak. As price chops in a range, every edge has sharp-looking candles and each one looks like a zone. With no structure broken, none of them tells you direction.
Don't trust blocks that fight the higher timeframe. A bullish order block on M15 may come from a small bounce in the middle of an H4 decline. If the big chart points down, buy zones on the small chart tend to be short-lived.
If price closes through the zone with a body, it's invalid; redrawing it and trying again just stretches a losing idea. Be careful around news too: a release can push through zones in one candle and come back, and that reaction comes from the calendar, not the structure.
Frequently asked questions
What is the difference between an order block and a supply or demand zone?
At heart it's the same idea: the place a sharp move started. A supply or demand zone is usually drawn from the whole pause before the move. An order block narrows it to one candle, the last opposite candle before the move, and requires the move to have broken structure. A narrow zone shortens the stop but also makes it more likely price pokes through it a little.
Do order blocks really show bank orders?
There is no way to know that from a chart. A candle shows how price moved, not who traded. It's healthier to read an order block in measurable terms: the last opposite candle before a sharp move that broke structure. Price may react there or may not, which is why you need a confirming candle and a stop beyond the structure.
How do you draw a bullish order block?
Find the sharp move up and the high it broke. Then mark the last down candle right before the candles that started the move. The box is usually drawn from that candle's high to its low; some traders use only the body. Either way, place the stop a little below the candle's low and below any sweep wick, not on the edge of the box.
