Sidebar: Evaluating Your Computer's Data Capacity
Before trading options online, traders must first consider whether they have the data signal and computer power necessary to process and store real-time options data. The number of optionable issues grows daily, and even though Signal doesn't transmit data on options that aren't trading at least 100 contracts a day, your computer and data server must still handle a large volume of data. In fact, you should count on having at least 16 MB of RAM (32 MB would be even better) in your DOS-compatible PC, plus 100 MB of space on your hard drive, particularly if you let the Signal data server automatically create symbols for you, which you probably should do. Otherwise, prune your symbol lists weekly to reduce the processing load on your machine.
