I'm already a member of your Extra service. Can I test out your "real-time" service on a trial basis?

Unfortunately testing the "Real Time" service is not possible on a trial basis. To receive Real Time charts you'll have to upgrade all of their
remaining time to the higher level of service. Keep in mind that our
real-time service is identical to our regular Extra service except that
the charts are created from non-delayed data. If you like Extra, but
don't like the data delay, you can upgrade with confidence.
