Order Blocks — Complete Guide

What is an Order Block?

An Order Block (OB) is the last opposing candle before a significant price move (displacement). It represents the zone where institutional traders placed their orders, creating a supply or demand area that price is likely to revisit.

In traditional trading, these are similar to supply and demand zones — but Order Blocks are more precise because they identify the exact candle where institutional activity occurred.

Bullish Order Block

A Bullish Order Block is the last bearish (red/down) candle before a strong bullish move:

                    ↑ Strong bullish move
                    │
                    │
    ░░░░░░░░░░░░░  │  ← This red candle = Bullish OB
                    │
         Previous candles

How to identify:

1. Find a strong upward displacement (large bullish candle or series of bullish candles)
2. Look at the last bearish candle before that displacement
3. Mark the entire range of that candle (open to close, or high to low for refined OB)
4. This zone is your Bullish Order Block

Trading the Bullish OB:

• Wait for price to retrace back to the OB zone
• Look for bullish confirmation (engulfing candle, pin bar, or LTF BOS)
• Enter long with stop loss below the OB
• Target the next swing high or liquidity level

Real Example — EUR/USD Bullish OB

During London session at 1:30 PM BD, EUR/USD has been dropping. A final red candle forms at 1.0855-1.0862 (the OB). Then a massive green candle explodes to 1.0910, breaking structure. Two hours later, price pulls back to 1.0860 (inside the OB). A bullish engulfing forms on the 5min chart. Entry: 1.0861, Stop: 1.0850, Target: 1.0920. Result: 1:5.4 R:R.

Bearish Order Block

A Bearish Order Block is the last bullish (green/up) candle before a strong bearish move:

How to identify:

1. Find a strong downward displacement
2. Look at the last bullish candle before that displacement
3. Mark the entire range of that candle
4. This is your Bearish Order Block

Trading the Bearish OB:

• Wait for price to retrace up to the OB zone
• Look for bearish confirmation
• Enter short with stop loss above the OB
• Target the next swing low or liquidity level

Order Block Validation Rules

Not all Order Blocks are valid. Use these filters:

✅ Valid Order Block:

• Created before a Break of Structure (BOS) or CHOCH
• Has a Fair Value Gap (FVG) associated with it
• Is in the premium zone (for bearish OB) or discount zone (for bullish OB)
• Has not been previously tested (fresh OB)
• Formed during London or NY Kill Zone

❌ Invalid Order Block:

• No displacement after the candle
• Already been tested/mitigated
• Against the higher timeframe trend
• Formed during low-volume Asian session
• Too far from current price (stale)

Types of Order Blocks

1. Standard Order Block

The basic last-opposing-candle before displacement. Most common type.

2. Breaker Block

An Order Block that has been violated (price passed through it). It then "flips" from support to resistance or vice versa. See Breaker Blocks.

3. Mitigation Block

When price returns to an OB that was previously broken, it becomes a Mitigation Block. See Mitigation Blocks.

4. Refined Order Block

Instead of using the full candle range, you use only the candle body (open to close) for a more precise entry zone with tighter stop losses.

5. Propulsion Block

An OB that occurs at a key structural level (like a previous BOS level), giving it extra confluence.

Order Block Entry Models

Model 1: Aggressive — Limit Order at OB

1. Identify a valid OB after BOS/CHOCH
2. Place a limit order at the 50% level of the OB (midpoint of the candle body)
3. Stop loss below the OB low (bullish) or above OB high (bearish)
4. Target: Next liquidity level (minimum 1:3 R:R)

Risk: Might not get filled; OB might not hold Reward: Best possible entry price

Model 2: Conservative — Confirmation at OB

1. Wait for price to enter the OB zone
2. Drop to a lower timeframe (5min or 1min)
3. Wait for a BOS on the lower timeframe in your trade direction
4. Enter after the LTF BOS with stop below the OB
5. Target: HTF swing high/low

Risk: Slightly worse entry price Reward: Higher confirmation, better win rate

Model 3: OB + FVG Confluence

1. Find an OB that has an overlapping FVG
2. The zone where both overlap is your premium entry zone
3. Use limit order at the 50% of the FVG within the OB
4. This is the highest-probability OB entry

Multi-Timeframe OB Analysis

High Timeframe OBs (Daily, 4H)

• Define major supply and demand zones
• Price reacts with 50-200+ pip moves
• Can hold for days or weeks
• Use for directional bias

Low Timeframe OBs (15min, 5min, 1min)

• Used for precision entries within HTF zones
• Tighter stops, better R:R
• Must align with HTF direction
• Best for intraday execution

Process

1. Daily: Mark the last valid OB in your trade direction
2. 4H: Find OBs within the Daily OB zone
3. 15min/5min: Look for refined OBs for entry
4. Enter on LTF OB reaction during Kill Zone

OB with Other SMC Concepts

OB + Liquidity Sweep

The most powerful setup:

1. Price sweeps a key high/low (liquidity grab)
2. This creates an OB at the extreme
3. Price returns to this OB for re-entry
4. The liquidity sweep adds massive confirmation

OB + FVG

When an OB overlaps with an FVG, you get double confluence. These zones have the highest probability.

OB + Premium/Discount

• Trade bullish OBs in discount (below equilibrium)
• Trade bearish OBs in premium (above equilibrium)

Common Mistakes

❌ Marking OBs Without Displacement

If there's no strong move after the candle, it's NOT an Order Block.

❌ Trading Tested OBs

An OB that has already been touched is mitigated. Fresh OBs have the highest probability.

❌ Ignoring HTF Direction

A bullish OB in a bearish HTF trend is likely to fail.

❌ Stop Loss Inside the OB

Your stop must be beyond the entire OB zone. Stops inside get hunted.

❌ Not Refining the OB

Using the full wick-to-wick range gives loose entries. Refine to the candle body for better R:R.

Risk Management

Real Trading Examples

Example 1: Gold (XAU/USD) — Bullish OB

Setup: Gold drops to $2,315 during London, creating a bearish candle (OB) at $2,318-$2,322 before exploding to $2,350 with a BOS. Entry: Price returns to $2,320 (middle of OB) at 7:30 PM BD. Bullish pin bar on 5min. Trade: Long $2,320, stop $2,312, target $2,355. Result: Gold hits $2,358. Risk: $8, Reward: $35 = 1:4.4 R:R.

Example 2: NAS100 — Bearish OB

Setup: NAS100 rallies during NY open, creating a bullish candle (OB) at 18,380-18,420 before crashing to 18,250. Entry: Price retraces to 18,400 (OB zone). Bearish engulfing on 15min. Trade: Short 18,395, stop 18,430, target 18,280. Result: NAS100 drops to 18,260. Risk: 35 pts, Reward: 115 pts = 1:3.3 R:R.

Pro Tips

FAQ

What's the difference between an Order Block and a supply/demand zone?

Order Blocks are more precise — they identify a single candle rather than a wide zone. They also require displacement as validation, making them more selective.

How long does an OB remain valid?

An OB is most powerful within 1-5 days of formation. After that, if price hasn't returned, the institutional interest may have shifted.

Can I use OBs on any instrument?

Yes — OBs work on forex, indices, crypto, gold, and stocks. Any market with institutional participation will form valid OBs.
