What Order Block means

An order block is a chart-defined zone used in some technical-analysis frameworks; candles alone do not establish actual institutional orders. Identified as the last opposing candle before an impulsive move.

In depth

An order block is a chart-zone concept used in some Smart Money Concepts and Inner Circle Trader interpretations. The zone is inferred from candles; it does not identify actual institutional orders. Some interpretations attribute these zones to large participants, but a price chart alone cannot establish their identity or holdings. The identification of order blocks follows precise rules. A bullish order block is defined as the last bearish (red/down) candle before a strong impulsive bullish move that breaks market structure to the upside. The entire range of that candle, from its open to its close (and sometimes including wicks), becomes a demand zone where institutions are believed to have placed unfilled buy orders.

A bearish order block is the mirror: the last bullish (green/up) candle before a strong impulsive bearish move. The proposed explanation links chart zones with gradual order execution, but candles alone do not establish that this explanation applies to a particular zone. When a large institution wants to buy a significant position — say $500 million worth of a stock — they cannot execute the entire order at once without moving the market against themselves. Instead, they break the order into smaller pieces and execute them over time, often during pullbacks.

Framework users may rank zones using these chosen criteria, without a validated reliability claim: (1) a strong impulsive move away from the block with multiple candles of continuation, (2) a break of prior structure (previous high or low), (3) the block has not been previously revisited (it is 'unmitigated'), and (4) it aligns with higher-timeframe trend direction. Some interpretations call a revisited zone mitigated. That vocabulary does not establish its predictive strength or the profitability of a later trade.

Key points

• Interprets price zones without proving institutional accumulation or distribution
• Bullish OB: last red candle before impulsive move up
• Price may revisit or move away from a marked block; continuation is uncertain

Why it matters when you are learning

Label the candle zone and the rule used to select it. Price candles alone cannot identify a particular institution's orders, remaining inventory or future buying intentions.

Practising Order Block on the simulator

Use the simulator as an observation exercise for Order Block. The main feature to identify is: Interprets price zones without proving institutional accumulation or distribution. A second feature to compare is: Bullish OB: last red candle before impulsive move up. A third feature to note is: Price may revisit or move away from a marked block; continuation is uncertain. The presence of the concept is not a prediction or a trade signal. Educational simulation only — not financial advice.
