An order block is the last opposing candle before a strong move. It marks a zone where price may react on a retest. Treat it as a location to watch, then confirm with orderflow before acting.
Bullish vs bearish order blocks
| Type | What it is | What you watch for |
|---|---|---|
| Bullish | Last down candle before a strong rally | Buyers defending on the retest |
| Bearish | Last up candle before a strong drop | Sellers defending on the retest |
| Mitigated | Zone already retested | Usually weaker the next time |
How to identify an order block
- Find a strong, impulsive move that breaks structure.
- Mark the last opposing candle before that move.
- Prefer zones that also took liquidity — see liquidity sweeps.
- Prioritize higher-timeframe zones and unmitigated ones.
Confirming order blocks with orderflow
A zone on a chart doesn't tell you whether anyone is defending it. When price returns, I look at the footprint: is aggressive selling being absorbed? Does delta flip? That's covered in footprint charts explained and orderflow trading explained.
Order blocks often line up with volume-based levels like the POC or value area edges. My daily ES & NQ orderflow levels share the levels I prepare each day — context, not trade signals.
Common mistakes
- Marking every candle as an order block.
- Entering blindly at the zone with no confirmation.
- Ignoring higher-timeframe context and news.
- Oversizing on funded accounts — know your drawdown.

What is an order block?+
An order block is the last opposing candle (or small range) before a strong impulsive move. Traders treat it as a zone where large orders may have been placed.
What is a bullish order block?+
The last down candle before a strong move up. Price returning to it may find buyers again.
What is a bearish order block?+
The last up candle before a strong move down. Price returning to it may find sellers again.

They are a way of marking reaction zones, not a guarantee. Many fail, so confirmation and risk management matter.
How do you confirm an order block?+
Look for a reaction when price returns: absorption, delta shifts or a failure to continue on the footprint chart.
Are order blocks the same as supply and demand?+
They're closely related. Order blocks are usually a narrower, more specific version of supply and demand zones.
Which timeframe is best for order blocks?+
Higher-timeframe order blocks tend to matter more. Many traders mark them on 1H–4H and execute on lower timeframes.
