I use Commsec but haven't upgraded to IRESS although I think I am entitled to use it for free anyway based on trades I have made. (Not sure about this as I think I am missing something when reading whether I qualify or not)

I am interested to know whether those who use this tool think it is worthwhile or those who use Commesc who haven't bothered.

Thanks in Advance
