What is an Order Block?

• A. Are areas of limit orders waiting to be executed. If you can see a liquidity sweep and break of structure, you have an order block.
• B. A market order that triggers a rapid price move with high volume.
• C. A chart pattern formed by two consecutive candles indicating reversal.
• D. A preset price level where orders are queued for days.

Answer: (A)

An order block is a price zone where resting liquidity sits, created by large players placing limit orders. These blocks act like pools of orders waiting to be executed, so when price revisits that zone you often see a liquidity sweep—where nearby stops or liquidity get triggered—followed by a break in the previous market structure as the move continues. That pattern shows the zone is being absorbed and the price is choosing a direction, which is why describing order blocks as areas of awaiting limit orders tied to a liquidity sweep and a structure break is the best fit.

Other options miss the idea: one describes a market order causing a rapid move (not about resting liquidity), another points to a candlestick reversal pattern (not about liquidity zones), and the last suggests a fixed price level where orders sit for days (which is too rigid and doesn’t capture the dynamic interaction of liquidity sweeps and structure breaks).
