Why We Built the Veilon Score (And Ditched the Rulebook)

March 23, 20268 min read

If you've ever read the Terms & Conditions of a prop firm — really read them — you know the feeling. Buried somewhere in page 14 is a clause you've never heard of that apparently means your account is now failed. No warning, no appeal, no refund.

We built Veilon because we were tired of it. And the Veilon Score is the centrepiece of how we do things differently.

The Hidden Rules Problem

Most prop firms didn't start with 30 rules. They started with a few basic ones — a profit target, a drawdown limit, maybe a minimum trading days requirement. Simple enough.

But here's what happens: a trader finds an edge that the firm's risk model can't handle. Maybe they're news trading around NFP and the firm's liquidity provider is getting hammered. Maybe they're scalping 50 micro-lots in rapid succession. Maybe they're holding positions through weekend gaps.

Instead of fixing their risk model, the firm bolts on another rule. “No trading within 2 minutes of high-impact news.” Then another. “No more than 3 positions open simultaneously.” Then another. “Consistency rule: no single day can exceed 40% of total profit.”

Before long, you're not evaluating a trader's ability. You're evaluating their ability to memorise and navigate a minefield of rules that exist purely because the firm couldn't manage their own risk properly. The rules aren't there to make you a better trader. They're there to protect a broken model.

One Score, Three Pillars, Zero Hidden Rules

The Veilon Score is a single number from 0 to 100 that measures the quality of your trading across three pillars:

Skill (35% of score)

Are you actually a good trader? We look at your win rate combined with your risk-to-reward ratio (expectancy), how smooth your equity curve is, and how well you control equity swings.

Expectancy — your profit factor and win rate combined. A 30% win rate with 3:1 R:R is excellent.
Equity Curve Smoothness — how linear and predictable your equity growth is (R² regression)
Equity Volatility — smaller intra-bar equity swings indicate better position sizing and timing

Risk Management (35% of score)

Are you protecting your capital? We evaluate your risk-to-reward ratios, stop loss discipline, margin usage relative to your balance, and whether you're revenge trading after losses.

Risk:Reward — higher R:R ratios score better (target ≥2:1)
Stop Loss Usage — consistently using stops shows professional risk management
Margin Discipline — keeping margin usage proportionate to account equity
Revenge Trading — re-entering within 2 minutes of a loss is detected and penalised

Behaviour (30% of score)

Are you trading responsibly and playing fair? We look at how many days you trade, the consistency of your position sizing, whether your profit comes from many trades or one lucky hit, and we detect prohibited practices like reverse trading across accounts.

Trading Days — spreading activity across multiple days shows patience and discipline
Position Sizing — consistent lot sizes show methodical risk management
Profit Concentration — profit spread across trades, not reliant on one lucky hit
Gambling Penalty — positions using excessive margin relative to balance are flagged
Reverse Trading — opposing positions on the same instrument across accounts are detected
HFT Detection — patterns of ultra-short trades (<30 seconds) are flagged

How It Actually Works

You need a Veilon Score of 75 or aboveto progress through your challenge phases and to request payouts. That's it. That's the only requirement beyond the standard profit target and drawdown limits.

But here's the key difference from every other prop firm rule: the Veilon Score is not a fail condition.If your score drops to 60, your account isn't failed. You don't lose your progress. You simply can't progress or request payouts until it recovers.

It's a filter, not a trap. It rewards responsible traders with faster progression, while encouraging those who need improvement to develop the skills and habits that actually matter — without punishing them for learning.

It Improves Naturally

This is the part we're most proud of. The Veilon Score is designed so that if you trade properly — use stops, size sensibly, don't revenge trade — your score will climb naturally over time as your trading history deepens and your equity curve smooths out.

The Skill pillar rewards traders whose equity grows steadily upward — the R² of your equity curve measures exactly this. The more consistently profitable you are, the smoother the curve, the higher your Skill score climbs. By the time you've been trading long enough and consistently enough to hit your profit target, your Veilon Score should already be above 75.

You shouldn't need to think about it. You just need to trade well.

Why This Matters Beyond the Challenge

Most prop firms make their money from challenge fees. Traders fail, buy again, fail again. The business model relies on failure. The rules are designed to maximise it.

We built the Veilon Score because we want the opposite. We want traders to pass. We want them funded. Because the Veilon Score doesn't just evaluate traders — it also functions as our internal risk management and signal-quality engine.

Every funded trader has a score. That score tells us, in real time, how skilled and responsible they are. It lets us build a book of funded traders weighted by quality, not just volume. A trader with an 85+ Veilon Score is someone whose equity curve is smooth, whose risk management is tight, and whose behaviour is clean — that's the kind of trader we want managing our capital. Our incentives are aligned with yours: the better you trade, the better it is for both of us.

Rules vs. Score: A Comparison

ScenarioTypical Prop FirmVeilon
You revenge trade once after a bad lossAccount failed (hidden rule violation)Risk Management score dips slightly. Keep trading well and it recovers.
40% of your total profit comes from one big tradeConsistency rule violation. Profit voided.Your Behaviour score may be lower, but one good trade doesn't penalise you. Trade more to spread the concentration.
You trade through a news eventTrades voided. Possible account termination.No restriction. If your risk management is sound, trade whatever events you want.
You open opposing positions across two accountsAccount terminated if caught (manual review).Automatically detected. Behaviour score drops. Pattern must stop to recover.
You hit your profit target with a score of 68N/A (different rule set)You can't progress yet, but your account isn't failed. Keep trading responsibly and your score will climb.

Focus on Trading, Not Rules

The Veilon Score exists so that you never have to wonder “did I break a rule I didn't know about?” There are no hidden clauses. No surprise disqualifications. No gotcha moments on page 14.

There's one number. It measures three things: your skill as a trader, how well you manage risk, and whether your behaviour is responsible. You can see it in real time on your dashboard, broken down into each pillar with specific sub-scores. You know exactly where you stand and exactly what to improve.

Trade well. The score takes care of itself.
