Here is something interest Brokerage that let u short penny short next some say u can't penny stock who them this!!!
Interactive Brokers
Interactive Brokers is a favorite among very active traders. Their Trader Workstation platform is considered one of the best on the market, and the company places no limits on penny stock functionality. Customers can short the securities and place market or limit orders. There are a few catches, though. The firm passes on all exchange fees, so trading can get pricey, and clients can’t trade securities that aren’t DTC eligible.
Cobra Trading
Another great fit for professional and very active traders, Cobra clients have access to four different platforms and direct-access trading, among other premium features and a large selection of penny stocks. Like Interactive Brokers, the brokerage also allows traders to short penny stocks, and place both market and limit orders. And unlike many competitors, they even give a discount – 20% off – for orders over 250,000 shares. On the other hand, customers will pay for the functionality. The firm passes on exchange fees to penny stock customers, on top of their already-hefty platform fees.
