i'm looking to finally do some trading away from home. this will NOT happen on a regular basis, but sometimes when i take a day off and have some downtime while waiting to meet up with some friends, or am travelling with family and want to enter / exit a quick trade while in the car. am hoping for some ideas / suggestions on what i need to do. i've done some reading, and know that some people have recommended a unit like a blackberry or iphone (which would work with the first option above, while meeting up with friends), and some have recommended an aircard (preferable with the laptop, when in the car with family). i know nothing about aircards. here's what i own: my cell phone is 8 years old? and i hardly use it. i don't text, don't even have pictures. so, obviously, i'd have to upgrade to SOMETHING if i did this. but i've done zero research on the phones. my laptop: dell vostro 1710, windows XP, 4GB. what i need: access to interactive brokers and at least one other brokerage account (i suspect tradestation would be most likely). i've seen IB has "mobile trader" realtick: for level 2 and very simple charts. (can this even be done on an iphone/blackberry?) i'd be watching no more than a few stocks, most likely one or two. my trades would ideally last no more than 2-3 hours. thanks for any suggestions, thoughts, and all that sort of thing.
