Propulsion Block (PB)
A Propulsion Block (PB) is an ICT Smart Money Concept that highlights a high-probability price reaction zone formed when a candle trades inside an Order Block and then propels price strongly away — indicating institutional order flow activation and momentum continuation.
Definition
A Propulsion Block is a price-action structure defined by a single candle that enters or interacts with an existing Order Block (OB), absorbs liquidity, and then drives price decisively away. It acts as a momentum accelerator and often becomes an efficient entry reference when price returns to retest the block.
Why It Matters
Propulsion Blocks represent activated institutional order flow and strong directional conviction. They can act as support/resistance on retests, capture smart money participation, and offer tighter invalidation levels and better risk-to-reward setups compared with raw Order Blocks.
How to Identify
- Locate a valid Order Block (OB) — supply (bearish OB) or demand (bullish OB).
- Identify a single candle that enters the Order Block and then drives price sharply away, forming a strong impulsive move.
- The propulsion candle typically has a dominant body with minimal opposing wick and often occurs after liquidity events (sweep of highs/lows or liquidity absorption).
- Confirm the propulsion move with momentum (e.g., strong range relative to recent candles). Higher timeframe propulsion blocks are more reliable but form on all timeframes.
How to Trade
- Wait for price to retrace back toward the Propulsion Block after its formation.
- Trade long at a Bullish Propulsion Block when price returns and confirms support (MSS/BOS/rejection) above the block.
- Trade short at a Bearish Propulsion Block when price retests and confirms resistance below the block.
- Use the Mean Threshold (50% Fib level) of the propulsion candle as a precision invalidation level — price should not close beyond this on the retest if the node remains valid.
- Place stop losses beyond structural extremes (below PB for longs, above for shorts), and target next liquidity pools or structural levels.
Common Confusions
A PB must enter an Order Block and then drive away with key liquidity and momentum — not just any large range candle.
An Order Block is the zone that institutions use; a PB is the reaction candle that activates price movement from that zone.
PB signals activated momentum in the direction of its impulse and should be confirmed with structure and liquidity context before assuming reversal.
Pre-Trade Checklist
- Order Block identified?
- Candle enters OB zone?
- Strong propulsion candle away from OB?
- Price returns to propulsion zone?
