Looking for a mobile device to trade stocks and options in which I can use outside of the house, and at times, outside of USA. Verizon works great in NYC, but how does their reception fare with other providers, specifically in: NY, CT, OR, NV, CA, Canada, Holland and Australia? In other words, can you actually use a PDA in other parts of the world to execute trades? And what, if any, complications may arise from that type of trading? Can someone explain the differences between a snapshot quote, a tick-by-tick, or streaming quotes? IB's Mobile Trader and ToS' thinkAnywhere, think Mobile offers snapshot. Quotrek claims to offer tick-by-tick, streaming. Can you really SEE the colorful scrolls of real time quotes (as you would on a PC) on QuoTrek. I don't know if IB will support QuoTrek cuz they already have their version. However, if they do, doesn't it get tricky having to change screens, as prices move when you are flipping from QuoTrek to IB just to place your trades? Would that then, be avantageous to just stick with IB or ToS using snapshot quotes? Which would you choose? Thanks.
