摘要

This study investigates the strategic spoofing order trading, including its characteristics, profitability, determinants, and real-time impacts. Both spoofing-buy and spoofing-sell strategies emerge, discernible among not only institutional investors but also individual traders. Spoofing trading is profitable, and traders are more likely to submit spoofing orders when volume and volatility are high, and they are more likely to submit spoofing-sell (buy) orders when the market price is high (low). Spoofing trading induces subsequent volume, spread, and volatility; spoofing-buy (sell) orders have a positive (negative) effect on subsequent prices. These findings provide support for the view that spoofing trading destabilizes the market.
