Order Blocks Explained: How to Trade Where Smart Money Entered

If Fair Value Gaps are the imbalance price leaves behind, Order Blocks are the launch pad it leaves from. An Order Block marks the spot where large orders were filled right before a strong move — and the market has a habit of returning to that level before continuing.

This guide breaks down what an order block really is, how to tell a strong one from a weak one, and how to turn that into a clean, repeatable entry.

An Order Block is the last opposing candle before a decisive, impulsive move — the last down-candle before a strong rally, or the last up-candle before a sharp drop. It represents the price range where institutional orders were absorbed before the market took off.

Why does it matter? Because not all of that institutional interest gets filled at once. When price drifts back to the block, the remaining orders — plus traders who missed the first move — tend to react there. That reaction is the edge.

Order Blocks are the natural companion to Fair Value Gaps. If you haven't yet, read how Fair Value Gaps actually work and how to trade the FVGs that hold — the two structures are strongest when they overlap.

A box on a chart is not a signal. What makes an order block worth trading is the quality of the move that created it:

• Impulse. The move out of the block should be strong and decisive — the more aggressive the departure, the more meaningful the zone.
• Imbalance. A genuine block usually leaves a Fair Value Gap behind it. That unfilled gap is a magnet that pulls price back to the zone.
• Freshness. An unmitigated block — one price hasn't returned to yet — carries more weight than one that's already been tested several times.
• Location. A block at a logical level of support or resistance, or in confluence with a higher timeframe, is far stronger than one in the middle of nowhere.

1. Mark the block — the last opposing candle before the impulsive move.
2. Wait for the retest. The trade is the return to the zone, not the impulse that made it.
3. Look for a reaction — a rejection wick, a shift in momentum, or an overlapping fair value gap filling inside the block.
4. Enter on the reaction, stop beyond the block. If price closes cleanly through the zone, the block is mitigated and the idea is invalid — exit by plan.

Because order blocks describe how price moves, the same rules apply to crypto, stocks, gold, or forex — and to any timeframe.

Marking and grading order blocks by hand across multiple timeframes is slow, and it's where most traders miss the best zones. FVG + OB Hunter detects every order block and fair value gap the moment it forms, grades each zone by strength, and alerts you when price returns — so you only act on the blocks that matter. It runs on TradingView as a one-time purchase. Want a full walkthrough? See how to use FVG + OB Hunter.
