Market manipulation

Placing orders you intend to cancel to fake supply or demand (layering stacks them across levels). Illegal under Dodd-Frank §747 and the EU MAR. We teach the statistical tell, not the technique.

Flood a venue with orders and instant cancellations to congest the data feed and slow competitors: a denial-of-service on the book. Manipulative under MAR and US rules; covered for detection.

Deliberately trigger a rapid move (often by setting off others’ stops or trend algos) to profit from the cascade you started. Prohibited conduct; the tell is order flow that initiates rather than follows.

Sending small orders to detect hidden liquidity or large resting interest. The grey zone of information-gathering, covered so you can recognise it being done to your orders.

Inflate a thin asset with hype and coordinated buying, then sell into the crowd. Ancient, illegal, and rampant in low-cap crypto; covered for recognition and detection.
