A strategy you create during a free trial of the Basic Plan is considered a "trial" strategy. It is not publicly visible and does not affect your track record in any way. No one can view its trades, and no one can subscribe to it.
Upgrading to a paid Trade Leader Plan will erase your "trial" strategy so that you can create a new one in its place that is publicly visible and eligible for gaining subscribers.
