I am trying to create a Universe with certain restraints, and I only want equities. This code keeps returning SPY and QQQ, which are funds. What would I add to this code to go about this? 

AddUniverse(coarse =>
{

return (from cf in coarse
where cf.Price > 10 && cf.Volume > 1000000
orderby cf.Volume descending
select cf.Symbol).Take(Count);
});
