Not a single student will pay more than what they're currently paying as a result of the new Pro Trader program.
In fact, in the case of old Live Trader subscribers, you're going to receive a discount at your next billing period:
LT Monthly subscribers will be charged $100 USD instead of $150 USD at your next billing.
LT Annual subscribers will be charged $997 USD instead of $1,500 USD at your next billing.
(As always, 10% GST applies to Australian residents)
