COBRA v2.0 — Triple Convergence

Strikes only when price, volume, and new money all agree. Exits when any of the three break.

What COBRA Does

Every 3 minutes, COBRA scans the top 25 assets by OI and checks three independent signals simultaneously:

1. Multi-timeframe momentum — 5m, 15m, and 1h must ALL agree on direction. If any disagrees, skip.
2. Volume confirmation — current bar volume must be ≥ 1.3x the 10-bar average. A move without volume is noise.
3. Open interest growth — OI must be trending up, meaning new money is entering. OI declining means the move is closing/liquidations, which reverses faster.

All three must pass. No exceptions. Optional boosters: SM alignment, funding direction, RSI room.

MANDATORY: DSL High Water Mode

COBRA MUST use DSL High Water Mode. This is not optional.

On Aftermath, initial SL is set inline with the entry order via the slTp field. DSL cron handles trailing updates only.

Spec: https://github.com/Senpi-ai/senpi-skills/blob/main/dsl-dynamic-stop-loss/dsl-high-water-spec%201.0.md

When creating DSL state files, you MUST include:

{
  "lockMode": "pct_of_high_water",
  "phase2TriggerRoe": 7,
  "tiers": [
    {"triggerPct": 7,  "lockHwPct": 30, "consecutiveBreachesRequired": 3},
    {"triggerPct": 12, "lockHwPct": 50, "consecutiveBreachesRequired": 2},
    {"triggerPct": 20, "lockHwPct": 70, "consecutiveBreachesRequired": 2},
    {"triggerPct": 30, "lockHwPct": 85, "consecutiveBreachesRequired": 1}
  ]
}

FALLBACK: Use tiersLegacyFallback from config until engine supports pct_of_high_water.

Entry Requirements

Pre-Entry Validation (Aftermath)

Before placing any order, preview it via POST /api/perpetuals/account/previews/place-limit-order (or place-market-order).

Check before executing:
- error field present -> abort and log reason
- percentSlippage above threshold (for example 0.5%) -> abort or reduce size
- collateralChange breaches per-position risk cap -> reduce size
- hasPosition: true when expecting a fresh entry -> refresh state and re-evaluate

Preview is free (no gas cost, no state change). Always preview before committing real funds.

Thesis Re-Evaluation (NEW in v2.0)

Every scan, COBRA checks held positions FIRST. The position holds as long as all three convergence signals are intact:

1. Momentum convergence — at least 2 of 3 timeframes (5m, 15m, 1h) must still agree with the direction. If 2+ flip against you, convergence is broken.
2. Volume alive — volume ratio must be ≥ 0.5x average. If volume dies below 0.5x, conviction has left.
3. SM still aligned — SM must not have flipped against the position.

If ANY of these break → thesis exit. The convergence that justified entry no longer exists.

Conviction-Scaled Margin

Dynamic Slots

Base 4 entries/day, unlocking to 8 on profitable days.

Risk Management

Cron Architecture

Notification Policy

ONLY alert: Position OPENED or CLOSED, risk triggered, critical error.
NEVER alert: Scanner found nothing, DSL routine, any reasoning.
All crons isolated. NO_REPLY for idle cycles.

Bootstrap Gate

Check config/bootstrap-complete.json every session. If missing: verify MCP, create scanner + DSL crons, write completion file, send: "🐍 COBRA is online. Scanning for triple convergence. Silence = no convergence."
