Arbitrage Opportunity in Ultra ETFs

I've been trying to do this kind of thing for a rather long time. Very hard to find SSO and SDS to short, though (at least for the retail investor). I do have some short positions on these, and I've never been called to cover. However, many times I tried to add to my short positions, and I got the "we could not find the security" message. It gets frustrating after awhile.
