symbol conflict

Hi all,

I'm having some issue making the algo trade these stocks. I know there are some problems with the universe of stocks having conflicting ticker symbols.
Is there any way to fix this issue?

the csv looks like this:
date,symbol,hour,minute,score
1/21/14,AGD,13,45,-1 <------- nothing happened
1/21/14,AOD,13,45,-1 <------- nothing happened
4/2/14,GOOG,14,39,-1 <------- nothing happened
4/14/14,NBR,11,20,-1
4/29/14,BRK_A,14,6,-1 <------- nothing happened
4/29/14,KO,14,6,-1
8/4/14,DMD,12,0,-1
10/22/14,NEWT,15,15,-1 <------- nothing happened
12/16/14,HTA,12,30,-1

Thanks in advance everyone.

Conflicts can sometimes be caused when a symbol is removed from one company and given to another.

using:
set_symbol_lookup_date('YYYY-MM-DD')
can sometime help.

Hey Jeremy,

Thanks for the post, I appreciate it. I have tinkered with the set_symbol_lookup_date function a bit but after using it the results are still the same.

edit:
perhaps I'm not using it correctly. Please advise
