ICT Propulsion Block: The Order Block Inside the Delivery Candle

The Propulsion Block is one of the most powerful and least-known OB variants in the ICT framework. It forms inside a strong delivery candle rather than before it — at the exact price zone where institutional participants added to their position mid-move to accelerate the delivery. When price returns to a Propulsion Block, the reversal is often sharper and faster than from a standard Order Block.

Key Takeaways

The Propulsion Block forms inside a strong delivery candle — specifically at the zone within the candle where institutional participants added to their position, creating a visible acceleration in the candle body
Unlike a standard Order Block (which forms in the candle before the move), a Propulsion Block forms within the delivery candle itself — typically visible on a lower timeframe sub-candle
The Propulsion Block is identified on the lower timeframe as a cluster of opposing-direction sub-candles inside the large delivery candle — the zone where price briefly consolidated before the move accelerated
Because the Propulsion Block represents additional institutional buying or selling at a specific price mid-move, price returns to it with high precision for re-entry opportunities
The Propulsion Block is most useful as a re-entry tool when the first entry at the standard OB has been missed — it provides a second opportunity to enter in the direction of a confirmed move

What is the ICT Propulsion Block?

The Propulsion Block is an Order Block sub-type that forms inside a strong delivery candle rather than before it. Where the standard Order Block is the last opposing candle before a directional move begins, the Propulsion Block is a zone inside an already-moving delivery candle — the specific price level where institutional participants added to their existing position mid-move to accelerate the delivery.

The term “propulsion” captures the function exactly: the Propulsion Block is the zone where additional institutional fuel was added to the move. When price returns to this zone on a retrace, the same institutional interest that propelled the initial move is expected to re-engage — often producing a sharper, faster reversal than the standard OB provides.

Why it exists

Large institutions rarely fill their entire position in a single order. They scale in — placing initial orders at the standard OB level, then adding to the position at pullbacks inside the delivery candle as the move confirms. The Propulsion Block is the zone where those scale-in orders were placed. It carries institutional weight precisely because it is inside an already-confirmed move, not before an uncertain one.

How to Identify a Propulsion Block

Propulsion Block identification requires dropping to a lower timeframe to examine the sub-candles inside the large delivery candle. The process:

Step 1: Identify a large, strong delivery candle on the higher timeframe (1H or 4H) — a candle with a large body and minimal wicks covering significant price range. This candle should be part of a clear directional displacement move.

Step 2: Drop to the lower timeframe (15M or 5M). The large delivery candle resolves into a series of sub-candles. Look for a cluster of opposing-direction sub-candles within the delivery — a brief pullback or consolidation zone inside the overall directional move.

Step 3: The Propulsion Block is the price range of that opposing-direction cluster — the zone where the sub-candles briefly moved against the primary delivery direction before the move resumed with renewed force. Mark this zone with a rectangle.

Step 4: The Propulsion Block top (for a bullish delivery) is the high of the opposing cluster. The Propulsion Block bottom is the low of the opposing cluster. This rectangle is the re-entry zone.

Propulsion Block vs Standard Order Block

The key distinction is timing relative to the directional move:

The Standard Order Block is the last opposing candle before the move begins. It represents the candle where institutions placed initial orders — before the direction was confirmed. Entry at the standard OB requires trusting that the move will begin from that level, without confirmation from the move itself.

The Propulsion Block forms inside a move that has already begun. It represents the level where institutions added to a position inside a confirmed delivery. Entry at the Propulsion Block comes after the move’s direction has been demonstrated by the initial delivery — the uncertainty is lower because the direction is already confirmed.

This is the Propulsion Block’s structural edge: it is a re-entry tool for traders who missed the initial OB entry, not a first-entry tool. It provides a second opportunity to join a confirmed move at a high-value institutional zone.

The Propulsion Block Re-Entry Trade

The Propulsion Block re-entry trade follows the initial delivery move. Price delivers from the standard OB, passes through the Propulsion Block zone (without pausing — this is inside the delivery candle), reaches its first target (the nearest liquidity pool), and then retraces. On the retrace, when price returns to the Propulsion Block zone, the re-entry trade is set up.

The entry is at the Propulsion Block zone — specifically at the top of the PB rectangle for a bullish re-entry (if price is retracing from above into the PB zone). The stop is placed below the PB bottom (for a bullish re-entry). The target is the draw on liquidity above the first target that was already cleared.

The re-entry at the Propulsion Block typically produces a faster reversal than the initial OB entry because the retracing price is encountering institutional interest at a zone where institutions already proved they were willing to buy. The second engagement with that level carries the same institutional weight as the first.

When Propulsion Blocks Are Highest Probability

Propulsion Blocks produce the strongest re-entry signals when several conditions align:

The initial delivery was strong. A weak, choppy initial move produces an unclear sub-structure inside the delivery candle — making the Propulsion Block zone ambiguous. A strong, fast delivery with large-bodied candles and minimal wicks produces a clean sub-structure with a clearly identifiable PB zone.

The PB zone aligns with an FVG. When the Propulsion Block zone also contains an open Fair Value Gap, the confluence of the PB and the FVG at the same level is a high-confidence re-entry zone. The FVG attracts price back to the zone; the PB confirms institutional interest at that exact level.

The retrace is shallow. A retrace that reaches the Propulsion Block zone without overshooting confirms that the primary directional momentum is intact. A retrace that blows through the PB bottom (for a bullish setup) and continues lower suggests the move structure has changed — the PB re-entry is no longer valid.

Kill zone timing. As with all ICT PD array entries, a Propulsion Block re-entry during a kill zone has significantly higher probability than one during the mid-day or Asian session.

Propulsion Block Examples: Bullish and Bearish

A bullish propulsion block forms during an uptrend when price makes a sharp leg higher, pauses at an OB that causes a brief consolidation, then explodes higher with a second displacement move that exceeds the first. The OB at the base of the first displacement is the propulsion block — the level that “launched” price into the powerful second leg. When price retraces in the future, this OB becomes the primary re-entry zone for the ongoing bullish delivery.

In concrete terms on NQ: price is at 17,200. A bullish OB at 17,100 launches price to 17,400 (the first leg, +300 points). Price consolidates briefly at 17,400, forming a new OB at 17,380. From 17,380, price explodes to 17,800 (the second leg, +400 points). The 17,380 OB that launched the second leg is the propulsion block. Future retracements to 17,380-17,400 are propulsion block re-entries targeting the next BSL above 17,800.

A bearish propulsion block: price at 18,500. A bearish OB at 18,550 launches price down to 18,200 (first leg, -300 points). Price retraces to form a new OB at 18,220. From 18,220, price declines to 17,800 (second leg, -400 points). The 18,220 OB is the bearish propulsion block. Future rallies to 18,220-18,250 are the bearish propulsion block re-entry zones targeting the next SSL below 17,800.

Why Propulsion Blocks Outperform Standard OBs for Re-Entry

A standard order block is the last candle before displacement — it marks where institutions entered a position. A propulsion block is an OB that already produced one significant leg before triggering an even more powerful second leg. This track record of producing institutional responses makes the propulsion block a higher-conviction re-entry zone than a standard OB that has never been tested.

The institutional logic: the OB that launched the second, more powerful leg was defended more aggressively than a standard first-touch OB. When price returns to a propulsion block on a retracement, the same institutional interest that launched the second leg is likely to defend the level again — the position that was built at the propulsion block is still being held and the institution will protect it on any test.

From a practical standpoint: when you identify a propulsion block and price retraces to it, you have two validating events — the OB itself AND the second displacement leg that confirmed the OB was defended the first time. Two events of institutional confirmation at the same price level make the third test (your entry) the highest-probability of the three. This is why experienced ICT traders specifically hunt for propulsion blocks on retracements rather than settling for the nearest standard OB.

Frequently Asked Questions

Is the Propulsion Block the same as the Hidden Order Block?+

They are related but distinct. Both form inside a delivery candle rather than before it. The Hidden OB is the first opposing candle inside the displacement at the very start of the delivery — the opening sub-candle. The Propulsion Block is a cluster of opposing sub-candles mid-delivery — the brief pullback zone partway through the move. The Hidden OB marks the entry level for the initial move; the Propulsion Block marks the re-entry level after the initial move has partially played out.

Can a delivery candle have more than one Propulsion Block?+

Yes. In a very long delivery candle (a large candle covering many pips over several hours), multiple brief opposing clusters may appear inside the move. Each cluster represents a Propulsion Block — a level where institutions scaled into their position. Mark each one. They are all potential re-entry zones on subsequent retraces, with the deepest (closest to the start of the delivery) being the highest-priority.

What is the minimum delivery candle size for a valid Propulsion Block?+

There is no precise rule, but as a guideline: the delivery candle should cover at least 3–4x the average candle range on that timeframe. A candle covering 1–2x the average range is unlikely to have meaningful sub-structure that reveals a clear Propulsion Block zone. The larger and more forceful the delivery candle, the more distinct the PB sub-structure will be.

Does the Propulsion Block work on all timeframes?+

Yes, but the most useful timeframe pairings are 4H/1H, 1H/15M, and 15M/5M. The delivery candle is identified on the higher timeframe; the PB sub-structure is revealed on the lower timeframe. Going smaller than 5M introduces too much noise to identify reliable PB clusters.

How is the Propulsion Block stop placement different from a standard OB stop?+

For a standard OB entry, the stop is placed below the OB bottom (for a bullish entry) — below the last down-close candle before the move. For a Propulsion Block re-entry, the stop is placed below the PB bottom — the lowest point of the opposing cluster inside the delivery candle. Because the PB is inside an already-confirmed move, the PB bottom is typically higher than the standard OB bottom, resulting in a tighter stop and better R:R.
