I like the Spread Hacker feature in ThinkorSwim, but they don't have a way to use it for the weekly's. I've emailed TOS and they say they'll put it on their list, but I'm not holding my breath. Anyone know of a tool like Spread Hacker that I can use for the weekly's? I want to seach for vertical spreads by "probability of touching" and "roi", which is based on margin required for the trade. Thanks in advance. rbfallon
