Order block vs supply and demand zone: same idea, two sizes

Both point at the same spot: where a strong move began. An order block narrows it to one candle; a supply or demand zone shades the small area around it.

The short answer

A Supply and demand zone is the area a strong move started from. A demand zone sits below price, where buyers pushed price up hard. A supply zone sits above price, where sellers pushed it down hard.

An Order block is a narrower version of the same idea. It's usually the last candle of the opposite color right before a strong move that breaks a turning point. Think of it as the spot inside the zone where the push began.

Order blocks: the narrow version

Here's a plain example. Price is falling. Then one red candle prints, and right after it, three big green candles shoot up and close above the last high. That last red candle is the order block. The idea is that big buyers stepped in there.

The good parts:

The hard parts:

See order blocks explained for a step-by-step way to find them.

Supply and demand zones: the wider version

Same example. Instead of one candle, you shade the whole small pause before the jump, from the lowest low to the top of the pause. That's the demand zone.

The good parts:

The hard parts:

More in supply and demand zones.

Same risk, different size, in units: you risk 1 unit either way. If the order-block stop is half as far as the zone stop, you can trade twice the size. But if price dips past the order block and then turns, that trade is stopped out and the zone trade isn't. That's a math example, not a promise.

How they overlap

In practice, the order block usually sits inside the supply or demand zone. Many traders mark the zone first, then use the order block to fine-tune the entry. Both are guesses about where big buyers or sellers may act again. Neither is a guarantee.

Check the trend first. A demand zone in an uptrend lines up with the bigger picture. One in a downtrend is a fight against it.

Which fits you?

Size every trade from your stop, whichever you use. The position size calculator does the math.

Questions

Is an order block the same as a supply and demand zone?

They're closely related. Both mark where a strong move started. An order block is one candle; a supply or demand zone is the wider area around it.

Which is better, order blocks or supply and demand?

Neither is better for everyone. Order blocks give tighter stops but more misses. Zones give more room but need smaller sizes. Test both on past charts.

How do I find an order block?

Look for a strong move that breaks a turning point. The last candle of the opposite color right before that move is the order block.

Do order blocks always hold?

No. Price can run straight through them. Treat them as places to watch, with a stop, never as a sure thing.
