Can anyone explain to me in a few short sentences how Whisper works exactly? I'm curious as to how a computer can seaerch through millions of stocks in a day to meet the criteria for a stock filter. Anyone have any ideas? I mean I know you need an NYSE data feed.... but once you have that and plug into the computer... doesn't the computer need to type a ticker before loading a stock's data? If not how does it work? Appreciate any help given.
