PMCC Scanner

Finds optimal Poor Man's Covered Call setups by scoring symbols on option chain quality.

What is PMCC?

Buy deep ITM LEAPS call (delta ~0.80) + Sell short-term OTM call (delta ~0.20) against it. Cheaper alternative to covered calls.

Instructions

Note: If uv is not installed or pyproject.toml is not found, replace uv run python with python in all commands below.

uv run python scripts/scan.py SYMBOLS [options]

Arguments

• SYMBOLS - Comma-separated tickers or path to JSON file from bullish scanner
• --min-leaps-days - Minimum LEAPS expiration in days (default: 270 = 9 months)
• --leaps-delta - Target LEAPS delta (default: 0.80)
• --short-delta - Target short call delta (default: 0.20)
• --output - Save results to JSON file (use this; Claude generates the report from the JSON)
• --report - Save auto-generated markdown to file (programmatic fallback only — prefer Claude-generated reports)

Scoring System (max possible: 14, range: -4 to 14)

| Category | Condition | Points | |----------|-----------|--------| | Delta Accuracy | LEAPS within ±0.05 | +2 | | | LEAPS within ±0.10 | +1 | | | Short within ±0.05 | +1 | | | Short within ±0.10 | +0.5 | | Liquidity | LEAPS vol+OI > 100 | +1 | | | LEAPS vol+OI > 20 | +0.5 | | | Short vol+OI > 500 | +1 | | | Short vol+OI > 100 | +0.5 | | Spread | LEAPS spread < 5% | +1 | | | LEAPS spread < 10% | +0.5 | | | Short spread < 10% | +1 | | | Short spread < 20% | +0.5 | | IV Level | 25-50% (ideal) | +2 | | | 20-60% | +1 | | Yield | Annual > 50% | +2 | | | Annual > 30% | +1 | | Trend | Price > SMA50 | +1 / -1 | | | RSI > 50 | +0.5 / -0.5 | | | MACD > signal | +0.5 / -0.5 | | Earnings | Next earnings > 45 days | +1.0 | | | Earnings within 45 days | -1.0 | | | Earnings within short expiry | -2.0 |

Output

Returns JSON with:

• criteria - Scan parameters used
• results - Array sorted by score:
• symbol, price, iv_pct, pmcc_score, max_possible_score (always 14)
• leaps - expiry, strike, delta, iv (calculated from bid/ask), last_price, bid/ask, spread%, volume, OI
• short - expiry, strike, delta, iv (calculated from bid/ask), last_price, bid/ask, spread%, volume, OI
• earnings_date - next earnings date (YYYY-MM-DD) or null
• metrics - net_debit, short_yield%, annual_yield%, capital_required
• score_breakdown - every scoring component as a <name>_delta (float) + <name> (explanation string) pair:
• Base: leaps_delta, short_delta, leaps_liquidity, short_liquidity, leaps_spread, short_spread, iv, yield
• Trend: trend_delta, trend (per-indicator dict)
• Earnings: earnings_delta, earnings
• All _delta values sum to pmcc_score
• errors - Symbols that failed (no options, insufficient data)

Report Generation

When the user asks for a report, a written analysis, or a saved document:

1. Run the scanner with --output to capture JSON data: ```bash uv run python scripts/scan.py SYMBOLS --output sandbox/PMCC_Scan_YYYY-MM-DD_HHmm.json ```

1. Read the JSON output.

1. Generate the markdown report yourself using the template defined in templates/markdown-template.md. Do not use the --report flag — that produces mechanical string output. Claude-generated reports include real analysis, contextual warnings, and trader-relevant narrative.

1. Save the generated markdown to sandbox/PMCC_Scan_YYYY-MM-DD_HHmm.md (match the JSON timestamp).

1. Display the full report to the user.

Examples

# Scan specific symbols
uv run python scripts/scan.py AAPL,MSFT,GOOGL,NVDA

# Scan and save JSON for report generation
uv run python scripts/scan.py AAPL,MSFT,GOOGL --output sandbox/PMCC_Scan_2026-01-15_1430.json

# Use output from bullish scanner
uv run python scripts/scan.py bullish_results.json

# Custom delta targets
uv run python scripts/scan.py AAPL,MSFT --leaps-delta 0.70 --short-delta 0.15

# Longer LEAPS (1 year minimum)
uv run python scripts/scan.py AAPL,MSFT --min-leaps-days 365

IV Calculation

IV is always computed from market price data via Black-Scholes, never taken from Yahoo Finance's impliedVolatility column:

• During trading hours: IV derived from bid/ask mid price
• Off-hours (bid=ask=0): IV derived from last price, using the option's last trade timestamp as the pricing moment (not current wall-clock time)

This applies to both compute_atm_iv (used for scanner baseline IV) and per-option delta calculations.

Key Constraints

• Short strike must be above LEAPS strike
• Options with bid = 0 and no last price are skipped
• Moderate IV (25-50%) scores highest

Interpretation

• Score > 12: Excellent candidate (strong structure + bullish trend + clear earnings runway)
• Score 10-12: Good candidate
• Score 6-10: Acceptable with caveats
• Score < 6: Poor structure, bearish trend, or earnings risk
• max_possible_score is always 14 — use pmcc_score / max_possible_score to gauge how close a candidate is to perfect

Dependencies

• numpy
• pandas
• scipy
• yfinance

Timezone

All timestamps and time-based calculations must use the America/New_York timezone. All JSON output must include generated_at (NY time string) and data_delay fields.
