    Paid. The challenge is live.

    Step 1

    Buy a challenge

    Pick a weight class and pay the fee once, in USDC. The account is live as soon as the payment confirms, usually in under a minute.

    Step 2

    Reach the target inside the limits

    Make 10% in one phase, without your equity touching the daily or the max loss line. There is no time limit. You need at least 5 trading days.

    Step 3

    Trade the funded account

    Verify your identity and trade the funded account, simulated like the challenge. Request a payout every 14 days: real USDC, sent on-chain. You keep 80%, rising to 90%, and the fee comes back with the first one.

Two lines you can't cross. That's the rulebook.

Most firms bury this part. Here are three sample accounts on the real limits: one that passed and two that did not. Move along the curve to read any hour.

Passed on day 12.

Flat at +10%, every day a trading day, and the best day was 22% of the profit, under the 50% cap. Next comes identity verification, then the funded account.

Profit target

10%+$2,500

Reach it with every position closed and at least 5 trading days. There is no second phase.

How it’s calculated

Balance ≥ B0 × (1 + 10%)

No open position or order

Best day ≤ 50% of profit

Daily loss limit

3%−$750

Your equity may not fall more than 3% of your starting balance below where the account stood at 00:00 UTC. We take the higher of balance and equity at that moment.

How it’s calculated

Ref = max(balance, equity) at 00:00 UTC

Floor = Ref − 3% × B0

Closed when Equity ≤ Floor

Max loss

6%−$1,500

Your equity may never touch 94% of your starting balance. The floor is fixed. It does not trail your profits.

How it’s calculated

Floor = B0 × (1 − 6%)

Closed when Equity ≤ Floor

  1. Your limits, always on screen

    Two scales above the chart show how much of each loss allowance is left, in dollars, the whole time you trade.

  2. Filled against Bulk’s live order book

    Simulated fills walk the real book at that moment, at Bulk’s real fees and funding.

  3. Positions flatten automatically at the line

    Every position shows the price at which the account would breach. Reach it and the engine closes everything.
