Index Futures market, along with their impact on market liquidity and volatility. Our results indicate a tendency among most individual day traders to behave as irrational contrarian traders. We also present consistent evidence to show that most individual day traders provide market liquidity by reducing the bid-ask spread, temporary price volatility and the temporal price impacts. Our results, which are consistent with the experimental results of Bloomfield et al. (2009), provide no support for the general criticism that day trading destabilizes the market while also exacerbating market volatility.
