Evaluation Model
Also known as: prop firm challenge, funding challenge, one-step evaluation, two-step challenge, instant funding
What is it?
An evaluation model is the structure a prop firm uses to decide whether to fund you: how many phases you must clear, what profit target each one carries, and which loss limits end the attempt. Three shapes dominate. A two-step evaluation splits the test across two phases, commonly an 8% target then a 5% target, and is the cheapest per unit of funding because most candidates never reach phase two.
| What you compare | Two-step | One-step | Instant funding |
|---|---|---|---|
| Phases before funding | 2 | 1 | 0 |
| Profit target | 8% then 5% | 10% | None to start |
| Maximum drawdown | 10% | 10% | 6% |
| Fee on $100,000 (illustrative) | $500 | $650 | $1,500 |
| Starting profit split | 80/20 | 80/20 | 50/50 until first payout |
| Typical time to funded | 6 to 12 weeks | 3 to 6 weeks | Immediate |
A one-step evaluation compresses it into a single 10% target, costing more but funding you sooner. Instant funding skips the test entirely for a much larger fee, then applies tighter rules and a reduced profit split until you have proved yourself in production. The trade-off is always the same: fee, speed and rule severity move against each other.
A $100,000 two-step challenge might cost $500 with a 10% total drawdown allowance, while instant funding at the same size costs $1,500 with a 6% drawdown and a 50/50 split until the first payout. Neither is inherently better - the right model depends on how quickly your strategy produces its edge and how much variance it carries along the way.
Why it matters: The evaluation model sets what you pay, how fast you reach funding, and how much room your strategy has before an ordinary losing streak ends the attempt.
A profit target that is aggressive relative to the drawdown allowance forces oversized positions, which is the most common cause of a failed evaluation.
Real-world example
A swing strategy averaging 2% a month clears an 8% two-step target in roughly four months, but a one-step 10% target on a 30-day clock would force it to trade five times its normal size.
How SignalBots handles it
SignalBots signals carry a stated reward-to-risk ratio, so you can estimate how many winning trades an evaluation's profit target actually requires before you pay the fee. See /risk-warning.
Pro tip
Divide the profit target by the maximum drawdown before buying: a ratio above 1.0 means one full drawdown of losses costs more than the target you have to reach.
Common pitfalls
Choosing the cheapest challenge without checking its time limit, then over-trading in the final week to reach a target a normal month would have delivered.
Frequently asked questions
Which evaluation model is easiest to pass?
Two-step evaluations carry the lowest per-phase targets, so each individual phase is easier, but you must clear two of them. One-step models need a bigger single push inside the same drawdown room.
Is instant funding worth the extra cost?
It removes evaluation risk and replaces it with tighter live rules and a reduced profit split until a first payout. It suits a strategy you have already proved, not one you are still testing.
Do evaluations have a time limit?
Many firms dropped the 30-day phase clock, but a minimum-trading-days requirement usually remains and inactivity rules can still close an unused challenge. Read both before assuming unlimited time.
Can I fail an evaluation and keep the same account?
No. A breach ends that attempt. You either buy a reset, which restores the starting balance for a reduced fee, or purchase a fresh challenge at full price.
Does the evaluation use real market prices?
Yes. Evaluations run on live price feeds through the firm's platform, so spread, slippage and news gaps behave as they would live. Only the capital behind the account is simulated.
