Order blocks: the footprints large orders leave
What an order block is, why price often reacts when it returns to one, and when a zone stops mattering.
Last updated 12 October 2026
Big participants such as funds, desks and proprietary traders can’t buy or sell all they want in a single click. They work their orders over minutes or hours, and when they finally push, price moves fast. An order block is a way to mark where that push started.
The definition MoneyHQ uses
On 5-minute candles, an order block is the last opposite-coloured candle before a sharp move:
- Bullish order block: the last red (down) candle before price rallies hard.
- Bearish order block: the last green (up) candle before price drops hard.
“Hard” means the move that follows is large compared with the stock’s normal 5-minute range, not just a few ticks. The zone is that candle’s range, from its low to its high.
The idea: the opposite candle is often where the large participant was still absorbing the other side (buying into selling, or selling into buying) just before they took over.
Why price often reacts there
If a large buyer accumulated inside a zone and part of their order was left unfilled, they may defend that price when it comes back. Other traders watch the same zones too. Either way, the zone becomes a place where buying (for a bullish block) or selling (for a bearish block) tends to show up again.
“Tends to” is the honest wording. Order blocks are a map of likely interest, not a promise of a bounce.
When a zone is “used up”
A zone stops mattering once price closes through it. A bullish block is used up when a candle closes below its low; a bearish block, when a candle closes above its high. On the board and stock pages, used-up zones are hatched and the active ones are shaded.
How to read it in MoneyHQ
- On the board, the dashed boxes on the money-flow lines are the order blocks of the day’s top 20 stocks on each side. Inside each leaderboard card, the dark bands are that stock’s blocks drawn against its volume profile.
- On a stock page, the shaded zone is the most relevant active block, listed under Levels and in the Trade plan as the order-block zone.
Things to keep in mind
- Context matters more than the box. A bullish block in a stock that is moving with a strong sector is a different situation from the same block in a stock moving alone against a weak market.
- Fresh zones matter more. A zone that has already been tested several times has less unfilled interest left.
- Size the risk to the zone. If an idea depends on a zone holding, the zone’s far edge is a natural place to say “I was wrong”. MoneyHQ’s trade plan shows that distance as a percentage.
Order blocks are one input. MoneyHQ puts them next to sector breadth, volume, VWAP and open interest so you can see whether the rest of the picture agrees.
