There is a revolution in Computers caused by the availability and huge sales of Mobile Devices; Smart Phones, like Galaxy S III, permit Internet and GPS anywhere. Tablet Computers, like Toshiba Thrive, have GPS navigation anywhere and Internet anywhere there is WiFi (a Hot Spot). Both Mobile Devices use Quickoffice Pro (QOP) for reading and editing, but it is difficult to create complex Word, Excel, or PowerPoint files such as the ones I use for trading weekly options. Both Mobile Devices use the Ice Cream Sandwich version of Android operating system. Excel and PowerPoint files can be transferred to the Mobile Devices by sending attachments to the gmail address of each Mobile Device. This book tells how you can use these Mobile Devices for Weekly Options trading. The trading software, SelfAdapSPXWeeklyVLTY, is available from the author for updating on a PC using Microsoft Office. Both the Smartphone and Tablet (which use the Android operating system) can use Quickoffice Pro (QOP) for computations and editing. Quickoffice Pro costs $15 and is compatible with Excel, Word, PowerPoint, and PDF and can be downloaded from the Internet."
