To qualify for a TTTPerformance account, you have to reach the profit target that corresponds to the plan you have purchased while making sure to respect all the rules.
As of July 1st, 2022, there will be no minimum trading days required to validate your account.
However, there is no maximum of days required to validate your account as long as the rules are respected. If the monthly subscription is due but you haven't reached the profit target, you will get to keep your balance if it's positive and continue trading in the same account.
