The core concept within the system is the notion of filters, which allow you to define a set of criteria to search by and the system will find all matching options.
Choose from 85 different search criteria and find the needle in the haystack that meets your exact requirements.
For any numeric value in the system you can specify the lower bound, upper bound, or both. The search engine will then find all matching options.
Compare filters to other filters. Want to find options where the ask price is 4 times the bid price? You can do that.
