These type of strategies have the ability to be declared a "test" strategy, but only if no trade signals have been entered and a legacy listing fee has already been purchased. You must declare your strategy as a test strategy before your enter any trade signals.
To designate a legacy listing strategy as a test strategy, click the Manage button on your strategy detail page, click Edit, then scroll down to the 3rd section area that says Non-Public Test System Status.
If you are unable to designate as a test strategy for any reason, you will be presented with a reason why. We cannot manually override the reason.
You may choose to kill the strategy and create a new strategy under a C2 Plan. See Plan Prices
