Drawdown Classification

Not all drawdowns are equal. The wrong response is more dangerous than the drawdown itself.

Class 1: Noise (Random Variance)

• Losing streak within expected statistical bounds for the system's WR.
• Test: At 60% WR, a 5-loss streak has P = 0.4^5 = 1.02%. Over 200 trades, ~2 expected.
• Response: Do nothing. Continue executing. Do NOT adjust.

Class 2: Structural (Setup Flaw)

• Losses concentrated in a specific setup, instrument, or time period.
• Test: Is the WR decline isolated to one setup type?
• Response: Quarantine the specific setup. Continue trading others.

Class 3: Thesis-Breaker (Edge Invalidation)

• Systematic WR decline across ALL setups.
• Test: Is the WR decline persistent (>30 trades)? Has market microstructure changed?
• Response: Full stop. Trigger circuit-breaker. Paper trade. Re-validate edge.

## Trade Journal Analysis (Last N Trades)

### Win Rate by Setup
| Setup | Trades | Wins | WR | Avg RR | EV/Trade |
|-------|--------|------|----|--------|----------|

### Win Rate Trend (Rolling 20)
[Trending UP / DOWN / FLAT] — current WR: XX%

### Drawdown Classification
Observed: X losses in last Y trades
P(this streak | WR=Z%): XX.X%
Classification: [NOISE / STRUCTURAL / THESIS-BREAKER]
Prescribed Action: [Continue / Quarantine setup X / Full stop]

### Edge Health
Verdict: [HEALTHY / DECAYING / CRITICAL]

Integration

• Feeds into zenith-execution for forward simulation (Monte Carlo)
• Validates Kelly assumptions (is the stated WR real?)
• Triggers circuit-breaker if edge decay is CRITICAL
