STKS: Stop Loss Orders not allowed??

["G. Dunn" <gjbkdunn@xxxxxxxxxxx>]

There are some stocks that my broker doesn't allow me to put stop loss
orders on. The explaination was that they are three levels/types of OTC
stocks.  Regular ones, another group that trade so thinly that Stop loss
orders are not allowed and penny type stocks.

Two stocks that it happened on this week were EFII and CTSH.  Volume on
these issues seems fine and they are definately NOT penny.
  
Is this a load of BS or not?  Are there three types of OTC stocks?
If this isn't BS then is there a web site that I can find out which stocks
are affected?


Thanks
Greg
