We use experimental asset markets to analyze trading under different transparency and information settings. We find that both liquidity and informed traders use undisclosed orders to compete for liquidity provision. In opaque markets, traders increase aggressiveness to improve execution probability. Without information friction, opacity enhances liquidity, especially toward the end of trading, and is beneficial for liquidity traders. Under informed trading, adverse selection drives market outcomes mainly around news announcements. Monopolistic insiders exploit opacity at the expense of large liquidity traders. Opacity does not affect informational efficiency with a monopolistic insider, but value discovery is faster with shared informational rents.
