Never tried TD but I do use IB and Fidelity to short DRYS... Most recently Fidelity had shares when I didn't .... The cost for shorting this is getting absurd though... Not that I can blame them with so many R/S
OTCsaved300 this has been suggested many times but I don't think there are that many shares available to short sell, the last I checked there were only a few shares available to sell short ..but if it worked it would be super fun ! And Profitable !
