- CCanceling an unexecuted limit order after market prices move unfavorably, where the original order was entered with genuine bona fide intent to execute.
- DFiling criminal prosecution charges directly through a FINRA arbitration panel to impose a federal prison sentence on a manipulative market participant.
Cevap
The prohibited practices are executing simultaneous buy and sell trades without a change in beneficial ownership (wash trading) and entering orders specifically to alter a security's closing price (marking the close).
Both wash trading (executing transactions without altering beneficial ownership) and marking the close (entering orders at the trading day's end to manipulate closing valuations) intentionally distort market signals and price integrity, making them prohibited fraudulent practices.
