Pre-Market vs. After-Hours Stock Trading

Risk #6: Bias toward limit orders

Many electronic trading systems currently accept only limit orders in the pre-market and after-hours sessions. Limit orders
may cause you to miss out on having a trade filled.

Risk #7: Competition with professional traders

Many of the after-hours traders are professionals with large institutions, such as mutual funds, who may have access to more
information than individual investors.

Risk #8: Computer delays

As with online trading, you may encounter during after-hours delays or failures in getting your order executed, including orders
to cancel or change your trades.
