Pre and post RTH hours stock trading

Hi, I need a refresher on this one.

What is the policy of C2 regarding GTC limit orders and pre and post market stock trading?

Can stock and/or ETF limit and stop orders (or market orders) be filled before 9:30 EST or after 16:00? If so, what is the overall time span allowed?


For stocks, C2 only fills orders during regular trading hours. So, you can post your orders during nights or weekends, but they won’t be filled until the market opens.
