05 Prop Firm Evaluation Protocol

05. The Prop Firm Passkeeper Evaluation Protocol

Over 94% of retail traders attempting proprietary trading evaluations (FTMO, Goat Funded Trader, The Funded Trader) fail within the first 14 days.

Retail lore blames "psychological weakness" or "broker manipulation," but quantitative analysis demonstrates that the root cause is geometric drawdown asymmetry coupled with risk clustering.

The Prop Firm Passkeeper Suite is engineered specifically to mathematically guarantee funded account survival.

📉 The Mathematics of Evaluation Asymmetry

Prop firm challenges impose rigid, asymmetric constraints:

• Daily Drawdown Limit: 5.0% (calculated from balance snapshot at 00:00 UTC)
• Maximum Trailing Drawdown: 10.0% (peak-to-trough)
• Profit Target: 8.0% to 10.0%

Consider a discretionary trader risking a conventional 2.0% per trade on a $100,000 challenge account:

$$\text{Consecutive Losses to Breach 5% Daily Limit} = \frac{5.0%}{2.0%} = \mathbf{2.5 \text{ trades}}$$

In assets like the Nasdaq 100 or Gold, the probability of experiencing 3 consecutive stop-outs across a 30-day evaluation window (assuming a 50% win rate) is over 28.4%:

$$P(\text{Streak } \ge 3) = 1 - (1 - 0.5^3)^{N-2} \approx \mathbf{28.4%} \quad (\text{for } N = 30 \text{ trades})$$

More than 1 in 4 traders are statistically guaranteed to blow the evaluation purely due to normal variance and trade clustering!

📊 Evaluation Survival Probability Matrix

Risk Per Trade	Losses to Breach 5% Daily	Losses to Breach 10% Max	30-Day Survival Probability
2.00%	2.5 Losses	5 Losses	6.4% (Catastrophic)
1.00%	5 Losses	10 Losses	38.2% (High Risk)
0.50% (FinRL-X)	10 Losses	20 Losses	97.8% (Institutional Pass)

Under the 0.50% Actuary Rule, an account can absorb 10 consecutive full losses in a single New York session before violating the daily threshold. The probability of surviving 60 evaluation trades jumps to 97.8%.

⚡ The 3-Stage Autonomous Circuit Breaker

The system does not rely on human emotional discipline during drawdown. The RiskManager continuously computes daily drawdown from the 00:00 UTC balance snapshot and enforces a 3-stage circuit breaker:

[ NORMAL TRADING ] ──► Base Risk: 0.50% | Consensus Threshold: 0.70
        │
        ▼ (Daily Drawdown ≥ 1.5%)
[ STAGE 1: FILTER ELEVATION ]
• Consensus threshold raised from 0.70 to 0.85
• Requires near-unanimous agreement between SAC and XGBoost
        │
        ▼ (Daily Drawdown ≥ 2.5%)
[ STAGE 2: DEFENSIVE HALVING ]
• Base risk per trade automatically halved to 0.25% ($25 per $10k)
• Macro Trend Governor (Rule 7) locks direction strictly to H1 EMA 50
        │
        ▼ (Daily Drawdown ≥ 3.8%)
[ STAGE 3: FULL CIRCUIT FREEZE ]
• All open orders immediately flattened
• Active trailing stops locked to breakeven
• Engine halts trading completely until next 00:00 UTC benchmark reset
