IB seems to have run out of a lot of ETFs to short lately.
Two that I follow, FAS and ERX, haven't been available to
short for a while now.
There are, of course, alternatives (such as buying the inverse
ETF), but that doesn't work very well if you're running automated
systems, at least not without running two long only systems
concurrently, one with a long ETF and the other with its inverse.
The problem with that strategy is that the results are going
to be different than if you ran just the long (or short) ETF going
long and short.

Does anyone know why you can't short SRS with Interactive Brokers anymore?
