Choose Your Weapons For Untethered Trading

摘要

My first time was at the airport in Burbank, Calif. I was passing the time reading news headlines on my cell phone when I noticed that the stock of Gemstar International Group, which supplies electronic TV listings to cable and satellite companies, had taken a fall of about five points, to $40 and change. On an impulse, I hit the menu button, clicked my way over to Ameritrade, and logged on. I got a realtime quote and then set up a limit order to buy the stock when it hit 35. I hit the send button, and a confirmation popped up. The whole transaction took less than a minute.
