Risk Management in a Crypto Prop Evaluation: Worked Examples
Risk advice in this industry is usually a list of adjectives. What a trader in an evaluation actually needs is arithmetic: how large this position can be, how much of today’s allowance is already committed, and how far the account is from a floor that does not move. Every example below is worked under the published ZoneX rules, labelled as an illustration, and states its assumptions. The percentages used are examples — the values that apply to you are the ones recorded for your purchased configuration.
The four rules the arithmetic rests on
Example 1 — Sizing a single position
Position size follows from the stop distance and the amount you are prepared to lose, not from a lot size or a leverage setting.
Illustration: one position
Assumptions: simulated balance $50,000; risk per trade chosen by the trader at 0.75%; BTC entry $60,000; stop $58,800; round-trip taker cost assumed at 0.10% of notional.
Costs are part of the loss the limits measure, so they belong in the worst case. Slippage can make the fill worse than the level set; this example assumes it does not.
Example 2 — Overlapping exposure and the remaining allowance
The daily allowance is measured on committed risk: what you have already lost today plus the worst case still open if every stop were hit, including costs.
Illustration: what is left today
Assumptions: same $50,000 account; recorded daily loss allowance 3% = $1,500, fixed at the 02:00 reset; two positions open, each sized as in Example 1.
- Realized today: −$450.
- Open worst case, position A: ≈ $394.
- Open worst case, position B: ≈ $394.
- A third position at the same risk ($394 worst case) would commit $1,632 — above the allowance.
If the two open positions are in highly correlated assets, treat them as closer to one commitment than two independent ones: correlation does not reduce the arithmetic, but it makes both stops likely to be hit together.
Example 3 — A static total drawdown floor
A static floor is calculated once and never recalculates — it does not rise as the account grows and does not change at the daily reset.
Illustration: the floor does not move
Assumptions: initial simulated balance $50,000; selected maximum total drawdown 8%. 8% is used here as an example, not a universal setting.
- Under a trailing model at the same 8%, the floor would have risen to $49,220 and room from current equity would be only $4,280.
This is why the early phase of an evaluation is the tightest: the room you have on day one is the smallest room you will ever have under a static floor.
Example 4 — Funding costs on a held perpetual
Illustration: a cost that accrues while you wait
Assumptions: $18,750 notional perpetual position; funding assumed at 0.01% per 8-hour interval against the position and held for 24 hours. Funding rates vary by venue and by hour and can be positive or negative.
- Small against a $375 risk budget — material against a $262 remaining allowance.
On the “safe” risk percentage
The two failures that are not about size
Optional, and not a substitute
The Pre-Violation Warning is an optional paid add-on priced at 20% of the Challenge fee. It flags actions that could breach a drawdown limit before you proceed. It does not change any rule, it does not guarantee protection against every breach, and the absence of a warning does not confirm that an action is compliant.
