In order to stay a TopTier Funded trader, you need to avoid breaching the simulated drawdown limits based on your funded account type and any other rules.
TopTier Funded (1 Phase)
Lose no more than 3% of the starting day's sim balance or the starting day's sim equity depending on which is higher. This would be the daily simulated drawdown limit.
Lose no more than 6% of the initial sim balance meaning that the account should not reach 94% of its initial value, this would be the max overall simulated drawdown limit. Do note that this trails as the account grows and locks at initial balance.
TopTier Funded Add-ons (2 Phase)
Lose no more than 5% of the starting day's sim balance or the starting day's sim equity depending on which is higher. This would be the daily simulated drawdown limit.
Lose no more than 10% (8% with the "8% Hybrid Max Loss / Profit Target" add-on) of the initial sim balance meaning that the account should not reach 90% (92% with the "8% Hybrid Max Loss / Profit Target" add-on) of its initial value, this would be the max overall simulated drawdown limit.
If you manage to avoid the above conditions whilst being profitable, you will be eligible for your first payout in 14 or 30 days from your first trade on the funded account depending on the funded account type. Thereafter payouts will be biweekly.
