Systems that short ETFs and stocks

Hi, I’m not having much luck with systems that short ETFs and stocks on C2. My broker never seems to be able to find shares to short, even widely-traded issues like TLT, so I just get error messages and no fills. Can system providers place GTC or limit orders or something rather than market orders, would that help?

I can understand if it was some little biotech company…but large ETFs should be shortable. My broker is MB Trading…maybe that’s the problem? Thanks

Janice maybe you would consider looking at my signal RPH? I trade inverse leveraged ETF’s. In a down market you don’t have to worry about shorting. Good for IRA or 401 accounts.

Thank You
