One-Step Challenge Prop Firm Math: How to Budget Your Risk

Introduction 

A prop firm, short for proprietary trading firm, lets you trade its money after you pass a paid test called a challenge. In a one-step challenge, that test has a single phase.

The catch is in the numbers. On Hola Prime's forex 1-Step Prime Challenge, you need to grow the account by 10% without ever letting it fall more than 6% below where it started.

So you have less room to lose than you need to gain. Whether you're about to buy your first challenge or you already trade one, that gap decides how much you can risk on every trade and how you handle the account once you pass.

The Numbers Behind a One-Step Challenge

Here is the short version of the math:

• The forex 1-Step Prime asks for a 10% profit target while capping losses at 6% overall and 3% per day.

• Because the target is bigger than the loss buffer, steady risk per trade matters more than any single big win.

• Lower risk per trade lets the account survive more losing trades before a limit closes it.

• A static loss limit stays at one level, while a trailing limit rises with your best end-of-day balance.

• The futures 1-Step Prime has no daily loss limit, so your own daily stop has to do that job.

• Once funded, every trade needs a stop loss and can risk no more than 2% of the starting balance.

• A breach ends the challenge, so a failed attempt means paying the fee again.

Why the Target-to-Loss Ratio Decides a One-Step Challenge

Every one-step challenge comes down to 2 numbers.

One is how much you must make. The other is how much you can lose.

A profit target is the gain you need to pass. A maximum loss limit is the furthest the account can fall below its starting balance before it closes.

On the forex 1-Step Prime Challenge, the target is about 1.7 times the maximum loss. You need to earn far more than you're ever allowed to lose.

In dollars, a $100,000 account has to reach $110,000. It also can't touch $94,000 at any point along the way.

That imbalance is why a one-step challenge punishes big swings. A couple of oversized losses can use up the whole buffer before the target is even in sight.

Raising your trade size after a few losses, to win the target back faster, is the quickest way to burn through that buffer.

If you want a refresher on the basic setup first, Hola Prime's guide to how a one-step challenge works walks through each stage.

The 1-Step Prime Rules Behind These Examples

Hola Prime's 1-Step Prime rules differ between forex and futures, so the examples use both versions.

Here is how the 2 versions compare on the forex trading rules and futures trading rules pages (as of the time of writing):

The forex version gives you more room to lose but asks for a bigger gain. The futures version asks for less and replaces the daily limit with a trailing one.

A consistency rule caps how much of your total profit can come from your single best day. On a $50,000 futures account, the 40% cap means no single day can count for more than $1,200 of the $3,000 target, so passing takes at least 3 profitable days.

Passing moves you to a simulated funded account, which tracks live market prices while Hola Prime supplies the capital.

If the forex numbers suit how you trade, the 1-Step Prime Challenge lets you hold trades through news and over weekends, then keep up to 95% of simulated profits on the monthly payout option once funded.

How Much Should You Risk per Trade in a One-Step Challenge?

Risk per trade is the amount you lose if a trade hits its stop loss. It decides how many losing trades the account can take before a limit closes it.

A stop loss is an order that closes a trade automatically at a price you set in advance.

On a $100,000 forex 1-Step Prime account, the daily limit starts at $3,000, and the overall limit sits at $6,000. The account closes the moment it reaches either level.

Each risk level therefore allows a set number of full losses in a row:

At 2% risk, 2 bad trades on the same day end the challenge. At 0.5%, the same day would need 6 straight losses to do it.

The table assumes each loss equals the planned risk. Slippage, which is the gap between your stop price and the price you actually get, can make a loss slightly bigger.

Your risk level also sets how many winners the target needs. At 1% risk and a winner that pays twice the risk, each winning trade adds $2,000, so the $10,000 target equals 5 net winners.

Every losing trade along the way adds half a winner back to that count.

None of these numbers predict how your trades will play out.

Trading carries a real risk of loss. A risk plan can't prevent losing trades, but it controls what each one costs.

How Static and Trailing Drawdowns Change Your One-Step Risk Budget

Drawdown is how far the account falls from a reference balance. Whether that reference stays put or moves changes how much room you really have.

Hola Prime's guide to drawdown limits in a prop challenge covers the general mechanics.

The 2 one-step accounts apply those mechanics differently:

A Static Limit on the Forex 1-Step Prime

A static limit never moves, so your profits build a real cushion.

On a $100,000 forex account, the floor stays at $94,000 whether you're up $8,000 or down $2,000. Once the account reaches $105,000, it can fall $11,000 before the overall limit is touched.

The 3% daily limit still applies on top of that. A larger cushion protects you across several days, though no single day can lose more than 3% of the previous close.

A Trailing Limit on the Futures 1-Step Prime

A trailing limit follows your highest end-of-day balance upward, so early profits lift the floor instead of widening your buffer.

End-of-day balance is your account value after the trading day closes. On a $50,000 futures account, the floor starts at $48,000. If the account closes a day at $51,000, the floor rises to $49,000.

The floor locks at $50,000, the starting balance, once the account reaches $52,000. Until then, your buffer stays at $2,000 no matter how much you've made.

The futures account also has no daily loss limit. One bad session can therefore use up the whole $2,000 buffer, so a personal daily stop, such as a fixed dollar loss after which you stop for the day, fills that gap.

If you trade index or commodity futures, the futures 1-Step Prime Challenge offers accounts up to $150,000. Once you're funded, it pays 90% of simulated profits on a weekly cycle.

Which Rules Still Apply on the Funded Account?

Passing removes the profit target and the minimum trading days, but the loss limits carry straight over.

Once you pass, you complete Know Your Customer (KYC) identity checks and sign an agreement.

Your simulated funded account then runs under these rules:

• Same loss limits: The forex account keeps its 3% daily and 6% fixed limits. The futures account keeps its trailing limit.

• 2% cap per trade idea: You can't risk more than 2% of the starting balance on any one trade idea, or 1% on the DX Futures platform. Overlapping positions, or a re-entry on the same asset within 10 minutes, count as one trade idea. Going over the cap ends the account.

• Mandatory stop loss: Every trade needs a stop loss. A loss beyond 2% on a trade without one counts as a breach.

• Account activity: Forex accounts need at least 1 trade every 30 days. Futures accounts need at least 1 closed trade every 7 days.

The per-trade cap is the biggest change. The challenge allows larger bets, so a habit built there can breach a funded account on its first oversized trade.

Payouts also come with conditions. A profit split is the share of simulated profits you keep.

On forex, the split depends on how often you withdraw:

The futures funded account pays 90% on a weekly cycle and needs 5 profitable days. The best day also can't exceed 35% of total profit.

First futures payouts are also capped, at $1,500 on a $50,000 account. According to the same rules pages, each payout follows an account review of up to 24 business hours. Approved requests are then processed within one hour of submission.

What Does a One-Step Challenge Really Cost?

The fee is the obvious cost, though the price changes with your account size and payout choice.

On the forex 1-Step Prime, a $5,000 account lists at $49 and a $100,000 account lists at $579 on the bi-weekly payout option (as of the time of writing). Choosing the 95% monthly option adds 20% to the price. Trading on cTrader instead of MetaTrader 5 adds $20.

Hola Prime lists a 100% challenge fee refund on the Prime Challenge, though the timing depends on the plan.

On the 2-Step Pro Challenge, for example, Hola Prime's forex FAQ says the refund is paid with your 4th successful payout, so confirm the 1-Step Prime terms before you count on it.

Hola Prime's rules also add a 2.5% processing fee to each payout. The minimum is $25 by bank wire and $5 by crypto.

A breach closes the challenge, so a failed attempt means paying the fee again. Because the percentages stay the same at every size, a $5,000 account lets you practice the same rules for a fraction of the $100,000 price.

The futures 1-Step Prime uses its own pricing, so check its plan page before you compare costs across markets.
