Spoofing, Layering and Wash Trading
Spoofing is placing orders you intend to cancel to trick others about supply or demand; layering does this with several orders at different prices. Wash trading is trading with yourself or a related party to create fake volume. All three are forms of market manipulation and are illegal in regulated markets.
Spoofing, layering and wash trading are ways of faking supply, demand or volume to mislead other traders. They are forms of market manipulation and are banned in regulated markets, though the exact laws differ by country.

Manipulation in plain words
Market manipulation is artificially distorting supply or demand for a security, for instance to drive its price sharply up or down.1
Spoofing is placing bids or offers you plan to cancel before they can be filled.2 Layering does this with many orders at several prices.
Wash-trading schemes trade back and forth to make a security look busier than it is.1
How these schemes work — and get caught
Fake intent
The spoofer places orders meant to be cancelled before they fill.3
Layer orders
Several fake orders sit at different prices to look like a wall.
Trade the other side
The real order fills as others react.
Cancel
Fake orders vanish before they trade.
Fake volume
Wash trades fake activity so demand looks higher or lower than it really is.1
Surveillance
FINRA firms must monitor for and stop repeated self-trades coming from the same algorithm or desk.4
Worked examples
Example 1 — Spoof
IllegalHypothetical: fake bids for 50,000 shares appear below the price; the spoofer sells 2,000 at 30.05, then cancels.
| Fake orders | Cancelled |
Placing orders you intend to cancel before they fill is spoofing, and it is illegal.2
Example 2 — Wash trade
Fake volumeHypothetical: two accounts of one person trade 100,000 shares back and forth.
| Real change in ownership | None |
Trading with yourself to make the stock look active is a form of manipulation.1
Example 3 — Small cap pump
Be carefulA hypothetical tiny stock jumps on heavy volume with no news.
| Risk | High |
Small, thinly traded microcap stocks are especially easy to manipulate.1
