TD Ameritrade Expands Pre and Post Market Trading Hours

Recommended Posts

We're pleased to announce that starting September 21, 2017, we will be expanding our Extended-Hours Trading sessions. You'll be able to trade during a continuous 13-hour trading session (Day + Ext. and GTC + Ext.) instead of 12.

Beginning on that date, the Day + Ext. and GTC + Ext. sessions will start an hour earlier, at 7 a.m. ET; the A.M.-only session will start an hour earlier, at 7 a.m. ET, and close at 9:28 a.m. ET instead of 9:15; and the P.M.-only session will start at 4:02 p.m. ET instead of 4:15.

All open orders within these sessions will be adjusted to align with the new times.

Here's a quick summary of the expanded hours:

Session Current Start Current Finish New Start New Finish
AM Extended-Hours Trading Session 8 a.m. ET 9:15 a.m. ET 7 a.m. ET 9.28 a.m. ET
Regular Market Hours 9:30 a.m. ET 4 p.m. ET    
PM Extended-Hours Trading Session 4:15 p.m. ET 8 p.m. ET 4:02 p.m. ET 8 p.m. ET
Day+Ext Session     7 a.m. ET 8 p.m. ET

This change will give you an extra hour to make investment decisions, take advantage of early morning news, factor in earnings announcements, and so on. It's part of our continuing effort to improve your trading experience.

If you have any questions, please let us know. Just reply to this message to write us, or call Client Services at 800-669-3900. We're available 24 hours a day, seven days a week.

FYI  from MT point of view:

TRADING - as they indicated

QUOTES - as of right now, until we switch to the new API, the timestamps will still start at 8 AM eastern, even though the quotes actually update (even right now) starting at 4 AM.  As for the end time with quotes, right now they update until 8PM. I assume that isn't going to change

So there won't be an issue trading those extended times through MT at TDA come the 21st?
