Order Blocks in Forex: How Institutional Footprints Mark Key Zones

What Is an Order Block?

An order block is the last opposing candle, or small cluster of candles, before a strong impulsive move. The idea is that large orders were filled there, and unfilled orders may remain. When price returns, the zone can act as support or resistance.

Bullish Order Blocks

A bullish order block is the last bearish candle before a strong rally. Mark the zone from the candle's high to its low. When price pulls back into this zone, buyers may step in again.

Bearish Order Blocks

A bearish order block is the last bullish candle before a sharp drop. A retest from below that shows rejection wicks or bearish engulfing candles can offer a short entry with a tight stop above the zone.

Confirming With Market Structure

The strongest order blocks produce a break of structure (BOS): the impulsive move breaks a prior swing high or low. Without a BOS, the zone is just a candle.

Valid vs Invalid Order Blocks

A valid order block usually has:

• Strong displacement away from the zone
• A break of structure
• An imbalance or fair value gap left behind
• No previous retest

Weak, overlapping moves create zones that rarely hold.

Risk Management

Place stops just beyond the zone and size your position so a failure costs no more than 1% of your account. Order blocks are probabilities, not guarantees.
