LiquidityLevelsOrder Block
An order block is the last candle that moves against a strong impulsive move, marked as an area where traders think significant orders were placed before the move began.

What an order block is
In the usual definition, a bullish order block is the last down candle before a strong move up that breaks structure. A bearish order block is the last up candle before a strong move down. The candle is marked as a zone, either its full range or its body, and traders watch the zone when price returns.
The logic is that a sharp move needs a lot of orders to power it, and the last opposing candle is where those orders may have been absorbed. This is an explanation traders find intuitive, not something that can be proven from chart data alone, so treat the label as a description of a pattern.
What makes one valid
Most practitioners require more than just an opposing candle. They look for displacement: a fast, large-bodied move away from the candle. They look for a break of structure that follows it. And they often prefer a zone that has not been revisited. Without those features, any candle in a trend qualifies, which makes the concept too loose to be useful.
Even with the criteria, many order blocks fail. Price may return and slice through the zone, or never return at all.
Breaker blocks
A breaker block is an order block that fails. Imagine a bullish order block that price breaks below. Traders then treat the same zone as potential resistance, as the earlier buyers are now in losing positions and some may exit when price returns to their entry. The zone has flipped its role, in much the same way that an inverse fair value gap is a flipped imbalance.
The labels are applied after the fact, so a zone starts as an order block and becomes a breaker if it fails.
How traders use order blocks
A typical approach is to wait for price to pull back into a valid order block in the direction of the trend, look for a reaction such as a reversal candle on a lower timeframe, and use the far side of the zone as a reference for risk. Others use order blocks as profit targets or as areas to avoid being on the wrong side.
None of this is reliable on its own. The concept is popular among retail traders, and the evidence that it adds value beyond ordinary support and resistance is limited. It is best treated as one way to organize a chart.
A simple way to practice
Mark every order block you can see on one timeframe for a week, using fixed criteria: the last opposing candle before a move that breaks structure with large bodies. Then record whether price returned to each zone, how it reacted, and whether it held or became a breaker. Over a few weeks you will see how selective you need to be for the concept to be useful.
Worked example
Common mistakes
- Marking any opposing candle as an order block without displacement or a structure break.
- Treating the zone as guaranteed support or resistance.
- Marking so many zones on a chart that price always touches one.
- Forgetting timeframe. A one-minute order block is far weaker than a daily one.
How it connects to ES, NQ, SPY and QQQ
Order blocks are drawn on ES, NQ, SPY and QQQ charts alike. Futures levels translate to ETF prices by dividing by roughly 10 and 41. Because futures trade overnight, order blocks formed in the Asia and London sessions may be visible before the cash market opens.
The Academy ideas of acceptance, rejection and value area edges often overlap with order blocks: an order block that sits at a value area edge draws more attention than one in the middle of nowhere.

This idea is applied to the current ES and NQ overnight structure every session.
