Jane Street- Usually considered the best. SIG- From what I gather this is the 2nd best, but I don't know big they are in NYC. Most people seem to work in Philly. Trillium Trading- Pays $500 a week I believe, not as much as Jane Street or SIG, but much better than nothing. Chimera Securities- Does not pay during training period, but pays salary after training period. FNYS- Considered one of the best, at least a couple of years ago, but I heard on WSO they were going under. I don't know how true this is. Any others?
