Going to tried the mobile demo, but its down until sunday night. How is the desktop demo? This site doesnt look like providing trading, only mentioned about exchanges, nothing about contract, fee etc. Probably have to contact them about everything.
Looks like T4 mobile doesn't offer charting.....do any of these solutions like the 1 from TWS offers BASIC charting ?
TWS for iPhone and Blackberry has basic charting. See http://interactivebrokers.com/en/pagemap/pagemap_mobiletrading.php iStockManager for iPhone has charting with a bunch of studies available, but (presumably because it gets its data feed from TDAmeritrade) charts are only available for stocks and indexes.
