Current Short Sale ban

Just wanted to know what is the current short sale ban on US Equities (which tickers are currently banned from shorting), I assume the following had expired in October 2008:

Any reply would be very much appreciated.

Thank You!

additionally, if anyone knows a site that summarizes all the current regulations, that'd be great.

Most short sale bans no longer exist at the end of trading daily. They are almost like circuit breaker rules where if price moves beyond a certain percentage shorting is not allowed. Your real concerning for checking if a stock is short-able should rest on whether there are shares available to short. Typically if average volume is over 100,000 K and the ipo date was more than three months in the past shares will be available to short for stocks on major exchanges.

So we don't really have a short-able list perse. Its just something the SEC will issue for a given day of trading is movement has exceeded a certain percentage decline.

Thanks Shaun! I am trying to run a simple algo with IBroker live data but the account is not letting me go short on several tickers, so I was wondering if this has something to do with the nature of our contract with IB or something with short sale ban. It would be great to get some more insight into this.
