I'd like to know what kind of setup (software , web resources, scanners) that people use when trading options.
I've been getting into writing options (US market) and designed my own tools to help out. Nothing fancy - its mainly just a spreadsheet that helps in recording trades etc.
I use charts from http://www.freestockcharts.com (not sure if that is with or without the trailing 's') and options quotes from the OIC education website.
What else can people recommend? I currently don't have any tools that can calculate payoffs, or a decent scanner.
