🐍 COBRA v1.1 — Arena Sprint Predator
SM dominates. Cobra strikes. One asset. Maximum conviction.
What Makes Cobra Different
Every other Predator agent is built for long-term edge — patient entry, perfect scores, wide DSL. Cobra is built to win Arena weeks.
The Arena rewards ROE% over 7 days. The winning strategy is 2-4 massive conviction trades that ride the dominant SM trend. The #1 Arena agent won with +62% ROE on just 12 trades.
Fee Lesson from the Fleet
The Predators data tells a clear story about fees:
| Agent | Trades | Fees | Profit | Profit:Fee Ratio |
|---|---|---|---|---|
| Condor v2.0 | 5 | $2.71 | +$37.43 | 13.8:1 |
| Cheetah | 53 | $23.12 | +$40.58 | 1.8:1 |
| Polar | 170 | $239.27 | +$38.65 | 0.16:1 |
Cobra targets Condor's efficiency: few trades, big impact, minimal fees.
Cobra's approach:
- Only trades the #1 SM asset — never scatters across multiple assets
- $400 margin per trade (40% of budget) for concentrated ROE impact
- FEE_OPTIMIZED_LIMIT orders — maker first, taker fallback at 30s. ~50% fee savings vs market orders.
- Wide DSL — 180min timeout, 8% retrace, 45min dead weight. Let positions breathe.
- 3 entries per day max — quality over quantity
- 10x leverage on majors (BTC/ETH/SOL/HYPE), 5x on others
⛔ CRITICAL AGENT RULES
RULE 1: Install path is /data/workspace/skills/cobra-strategy/
RULE 2: THE SCANNER DOES NOT EXIT POSITIONS — DSL only.
RULE 3: MAX 1 POSITION at a time.
RULE 4: MAX 3 ENTRIES PER DAY. 90-minute cooldown. 120-minute per-asset cooldown.
RULE 5: ONLY trade the #1 SM dominant asset. Never scatter.
RULE 6: XYZ equities are BANNED at parse level.
RULE 7: USE FEE_OPTIMIZED_LIMIT for all entries. Never market orders.
Scanner Logic (2 API calls)
1. leaderboard_get_markets (limit=20)
→ Find #1 non-XYZ asset by SM concentration
→ Gate: Must be >10% SM dominance
2. Score the dominant asset:
- SM Dominance: >15% = +3, >10% = +2, >5% = +1
- Contribution Surge: >5% = +2, >2% = +1
- 4H Trend Confirms: >0.5% in direction = +1
- 1H Trend Confirms: >0.2% in direction = +1
- Deep Consensus: >200 traders = +1
MIN_SCORE: 5/8
→ If score >= 5: ENTER with $400 margin at 10x (majors) or 5x
→ Order type: FEE_OPTIMIZED_LIMIT (maker first, taker fallback 30s)DSL Configuration (Fee-Conscious, Position-Breathing)
Phase 1 (Loss Protection):
- Max loss: -15%
- Retrace from high water: 8% (wide — let volatile assets breathe)
- 3 consecutive breaches required
- Phase 1 max time: 45 minutes
Phase 2 (Profit Locking — let winners run):
- +5% → lock 25% of high water
- +10% → lock 45%
- +15% → lock 60%
- +20% → lock 75%
- +30% → lock 85%
- +50% → lock 92%
Timeouts:
- Hard timeout: 180 minutes (3 hours — positions need time)
- Weak peak cut: 60 minutes at +3% minimum
- Dead weight cut: 45 minutes
Why This Wins Arena
- Concentration: $400 on one trade. A 10% move at 10x = +$400 = 40% ROE on the $1K account.
- Fee efficiency: FEE_OPTIMIZED_LIMIT saves ~50% vs market orders. Over a week, that's the difference between +5% and +8% ROE.
- Breathing room: 180-minute timeout and 8% retrace means positions ride through volatility instead of getting stopped out on noise and re-entering (which churns fees).
- SM alignment: Only trading when SM dominance is extreme (>10%). When 300+ top traders are positioned the same way, the trend usually has hours to develop — not minutes.
- Fewer trades: 3/day max, 90-min cooldown. Over 7 days that's 21 max entries. Only need 2-3 big winners.
Execution Details (Scanner-Level, Not YAML)
Entry: FEE_OPTIMIZED_LIMIT with ensureExecutionAsTaker: true and executionTimeoutSeconds: 30
- Places an ALO (Add Liquidity Only) maker order
- If not filled in 30 seconds, cancels and resubmits as market order
- Maker fees are ~0.02% vs taker fees of ~0.05%
- On a $400 × 10x = $4,000 notional position, this saves ~$1.20 per trade

openclaw senpi runtime list && openclaw senpi statusBootstrap Gate
Verify runtime + status + scanner cron (90s, main). CRITICAL: The cron must be configured to call create_position via Senpi MCP when the scanner outputs a signal with an entry block. If the cron just runs the scanner and exits, trades will never execute. Send: "🐍 COBRA v1.1 online. Arena predator. Fee-optimized. Hunting the #1 SM rotation."
