you cannot skip a symbol based on a condition based on the symbol, however, you can skip subsequent code using if(). If you have an undefined variable you have to assign it some value before it is used or (if memory serves me right) use nz(VarGet()) - this returns zero when the variable is not initialized.


The ticker will however show up in the explorer report, I don't think you can suppress that.
