When can I place an order?

You may place Market, Limit, Stop, Stop Limit, or Trailing Stop orders from 9:30 AM ET to 4:00 PM ET. You may only place limit orders during our extended market hours.

There is no guarantee that your Limit order will be filled instantly or at all. Placing a market order gives you the best opportunity to get a fill in your order, in which case it will buy/sell the security at the market price.
