I'm wondering why this algorithm did not trade CBLI, INMB, PRCP, IMV, DARE, or CLBS on 7/14.  I thought it might be because those symbols are not in the top 1,000 dollar volume from the previous day like the coarse universe selection is looking for?  But when I raise the numberOfSymbols field above 1,000, I get a Runtime Error.  Do you know why I'm seeing that error?  And/or why the above symbols did not get traded?
