TDA traders can log into uVest today using their web browser:
I’m continually adding new features. Today, just completed the core functionality for querying an option chain. With 165,000 contracts, SPX can be a challenge to analyze. uVest has a new Data Table view that allows you to filter on important fields, sort column, and display various column groups so you can quickly find the contract that meets your criteria.
The best part is this is FREE, and I hope to keep many of these features free indefinitely.
