Ballast

Trailing-drawdown cushion calculator

The two numbers that keep a prop account alive: how much room you have to the trailing floor, and the biggest size you can take without threatening it.

Your account

Picking an account fills in the rules below — then set Current and Peak to your live balances.
Your account balance right now.
The highest your balance has ever reached — the high-water mark the trailing floor follows. If you're unsure, set it equal to your current balance.
Room to your floor
$4,200
Your account dies at $147,000
Locks at $159,000 once your peak reaches $164,000

Until then, making money buys you no extra room— the floor climbs with you and your cushion stays at $5,000. You need another $12,000 of peak before that changes.

Intraday trailing follows your peak including unrealised profit— a floating winner that round-trips still ratchets this floor up permanently. Bank profit; don't admire it.

Your setups - risk per trade vs your cushion

Enter each setup the way you actually trade it (stops in ticks, and set the contracts). Ballast shows what a full stop costs and how much of your remaining failure buffer — the number above — it eats. That is what decides whether a strategy you have an edge on can still quietly end the account.

Risk per stop: $3,375Reward: $3,525 (1.04R)Share of buffer: 80.4%Full stops left: 1

One stop here is 80% of everything standing between you and a blown account.

Risk per stop: $6,250Reward: $8,750 (1.40R)Share of buffer: 148.8%Full stops left: 0

A single full stop on this setup breaches your floor — this trade alone can end the account.
