How does one get in on after-hours trading on IB?

I have several securities in my account, including a little TVIX. Since its the biggest mover, I always see it swinging WILDLY in the after market, and I'm not just talking at 4:01 or 4:05 eastern, it seems to fluctuate for several hours after the close.

However, if I try and place an order at any time after close (heck, even right at 4:00), it gives me a note that the exchange is closed or what not.

How can I participate in the after-market? I swear there has been several times when I've seen TVIX go crazy after-hours, and I tell my self I'd sell my little TVIX if I could and make a killing, but I couldn't, and sure enough the next day it had dropped way back down.

Thanks!

Thank you tommcginnis and d08!!!

 

Not sure why they don't allow that by default. You're not taking on any more risk by buying or selling after hours than during regular trading hours assuming limit orders are used.

 

Note that you can also trade SPX and VIX options after hours with IB between 2am and 815am ct.

 

Spread sucks after hours.

 

What is this assuming dribble? Market orders are not allowed in after hours.

 

Much less liquidity, less support and a need to be informed when you are trading.

 

If you're planning to possibly exit the position in after-hours, yes, agree. But if you are planning to hold the position at least until next regular trading hours, then liquidity is not really a concern. If I want to buy or sell some stock or ETF at a specific price and hold it for at least a few days (swing / position trading or long term investment), I don't really care if I get filled during regular trading hours or outside of regular trading hours.
