IB Tactical Collar
Generate a tactical collar strategy report for protecting PMCC positions through earnings or high-risk events.
Prerequisites
User must have TWS or IB Gateway running locally with API enabled:
- Paper trading: port 7497
- Live trading: port 7496
Instructions
Step 1: Gather Data
uv run python scripts/collar.py SYMBOL [--port PORT] [--account ACCOUNT]
The script returns JSON to stdout with all position and scenario data.
Step 2: Format Report
Read
templates/markdown-template.md for formatting instructions. Generate a markdown report from the JSON data and save to sandbox/.
Step 3: Report Results
Present key findings to the user: recommended put protection, cost/benefit, and the saved report path.
Arguments
- Stock symbol to analyze (must be in portfolio)SYMBOL
- IB port (default: 7496 for live trading)--port
- Specific account ID (optional, searches all accounts)--account
JSON Output
The script returns JSON with these key fields:

- Basic infocurrent_price
,long_strike
,long_expiry
,long_qty
- LEAPS positionlong_cost
- List of short callsshort_positions

Report Sections
- Position Summary: Current PMCC structure (long calls, short calls)
- PMCC Health Check: Is structure proper (short > long strike) or broken?
- Earnings Risk: Next earnings date and days until event
- Put Duration Analysis: Comparison of short vs medium vs long-dated puts
- Collar Scenarios: Gap up, flat, gap down outcomes with each put duration
- Cost/Benefit Analysis: Insurance cost vs protection value
- Implementation Timeline: Step-by-step checklist with dates
- Recommendation: Optimal put strike and expiration
Key Concepts
Proper PMCC Structure:
- Long deep ITM LEAPS call
- Short OTM calls ABOVE long strike
- No additional margin required for collar
Broken PMCC Structure:
- Long call is now OTM (after crash)
- Short calls BELOW long strike require margin
- Collar still works but margin implications exist
Tactical Collar:
- Buy protective puts ONLY before high-risk events (earnings)
- Sell puts after event passes
- Balances income generation with crash protection
Put Duration Trade-offs:
- Short-dated: Cheaper, more gamma, but zero salvage on gap up
- Medium-dated (2-4 weeks): Best balance of cost, gamma, and salvage
- Long-dated: Preserves value on gap up, but expensive and less gamma
