What is Prop Firm Buffer Zone (Safety Reserve)?
A prop firm buffer zone (or safety threshold reserve) is a mandatory profit cushion—typically equal to the account's initial maximum drawdown plus $100—that a funded trader must accumulate and leave untouched in the account before withdrawing 100% of subsequent profits.
Mathematical Calculation
Once your funded account reaches the Buffer Lock Threshold, your trailing drawdown permanently locks at the starting balance (+ $100), and any profit earned above the buffer becomes eligible for withdrawal without shrinking your trading cushion.

$50K Funded Account Buffer Zone Math
Initial Funded State: Balance is $50,000; trailing liquidation floor is $47,500.
Buffer Zone Requirement: $2,500 (initial drawdown) + $100 = $52,600 safety threshold.
Building the Cushion: Trader grows balance to $54,100. Drawdown floor is now permanently locked at $50,100.
Maximum Safe Withdrawal: $54,100 - $52,600 buffer = $1,500 withdrawable while keeping a full $2,500 trading cushion intact.
