Aggressive and Passive Orders
Aggressive buyers and sellers cross the spread with market orders and take liquidity; passive orders wait in the book as limit orders and provide it.
An aggressive order crosses the spread to trade immediately; a passive order rests in the book waiting to be hit. The split explains who moves price and why exchanges charge makers and takers differently.

The difference in plain words
Aggressive orders are market orders that trade right away against the best bid or offer, using up available liquidity and often nudging the price.1
Passive orders are limit orders that wait in the book; they only fill at the chosen price or a better one.2
Many exchanges reward the passive side: under maker-taker pricing the order that adds liquidity earns a small rebate, while the order that removes it pays a fee.3
How aggressive and passive orders interact
Passive orders rest
Limit orders sit at bid and ask.
Aggressive order arrives
A market or marketable limit order crosses the spread.
Trade prints
Execution happens at the resting price.
Fees are applied
Check your venue's fee schedule: adding liquidity usually earns a per-share rebate, and taking it usually costs a per-share fee.3
Price moves if levels clear
Aggression eats through the book.
Choose your style
Choose aggressive when getting filled matters most — a market order is sure to execute, but the final price is not fixed.2
Worked examples
Example 1 — Taker buy
Pays feeHypothetical bid 9.99 / ask 10.00; a trader sends a market buy for 100 shares.
| Fill | 10.00 |
| Fee | 0.30 |
Because the order crossed the spread and removed liquidity, it paid the taker fee.3
Example 2 — Maker buy
Earns rebateA trader places a limit buy at 9.99 and is filled later.
| Fill | 9.99 |
| Rebate | 0.20 |
The liquidity providing “maker” receives a rebate — but the fill was not guaranteed.3
Example 3 — Aggression moves price
Price liftedHypothetical asks: 100 @ 10.00, 100 @ 10.01. A 200-share market buy arrives.
| Avg fill | 10.005 |
| New ask | Higher |
The burst of market orders cleared the best price levels, which is how aggressive flow moves price.1

|---|---|---|
| Order type | Market / marketable limit | Resting limit |

| Price | Pays the spread | Earns the spread |
| Fees | Usually higher | Often lower or rebate |

Going deeper
Read as far as you need. Each level builds on the one before it.
Order types
Beginner
A market order guarantees execution but does not guarantee the execution price; a limit order fixes the price at a specific price or better.2
Maker-taker pricing
Intermediate
Maker-taker pricing exists to attract resting orders: venues pay liquidity providers a small rebate per share and recover it from takers.3
Reading flow
Advanced
When heavy aggressive volume hits a level and the passive side keeps refilling without price moving, that is absorption.1
Common mistakes

You pay spread and fees.
Assuming limits fill
Price may never return.
Ignoring fee tiers
Maker and taker rates differ.
Equating volume with direction
Check who was aggressive.
Check your understanding
Test yourself before moving on. Each answer comes with an explanation.
