[amibroker] problem with position and GetBacktesterObject();

[raskoks]

Hi,
I wonder how to use 
bo = GetBacktesterObject();
and maybe loop like this:

 for( trade = bo.GetFirstTrade(); trade; trade = bo.GetNextTrade() ) 
     { 
          // trade variable now holds Trade object

     }

Too find information about current bactester position.
I need to know for every bar information about position (long,short) because 
some signals shoud be use only when i have long and some for shorts.
Maybe someone can help mi with this kind of problem.

Best regards
raskoks
