Free trials of platinum membership are only offered in special cases, such as certain promotional periods. However, for just $7, those new to Base Camp Trading can enjoy all the benefits of Platinum Membership for 30 days. It's open to anyone who hasn't yet taken advantage of the offer. The $7 trial membership can be accessed on Base Camp Trading's home page or via this link.
Those who join the $7 trial will automatically be enrolled at the regular monthly rate after the trial so you'll be able to continue to use the benefits of the Platinum Membership without interruption. If continuing with membership isn't desired, just cancel by the end of the trial period.
