I have a 600k account and am looking for a few brokers that have the best borrows. I've been told TOS, Broadstreet, IB Capstone, and sure trader. Any thoughts? I'm looking to trade hard to borrow stocks and otc and pinksheeters. I'm thinking I need 1/4 split up between each broker. Any brokers you can reccommend for the hard to borrow and illiquid stuff?
