💫 Practical option plays · Systematic theta
Theta decay exploration
Systematically sell 30–45 DTE options and manage at 50% profit. Consistent theta capture with defined-risk structures (iron condors, credit spreads).
Setup
- Instrument: Nifty/Sensex monthly expiries; use 30-45 DTE for cleanest theta profile
- Structure: iron condor or credit spread — defined risk is critical for systematic deployment
- Strike selection: short leg at ~15-20 delta; wings at 3-5% further OTM
- India VIX filter: only enter when VIX > 12 (premium adequate)
Entry
Rules-based: on the first trading day at least 30 DTE from the current monthly expiry (typically 3rd Friday-Tuesday of the month), enter the defined-risk structure.
Exit
Take profit at 50% of max credit. Time-based exit at 21 DTE regardless of P&L (avoid last 3 weeks of gamma). Loss stop at 200% of credit received.
Stop-loss
Combined loss ≥ 200% of credit → close position. Also 21-DTE time exit as a hard rule to escape the gamma zone.
When it works
- Low-to-medium IV regime (VIX 12-18) where premium exceeds realized vol
- Consistent monthly execution over many cycles — the edge shows up over 20+ trades
- Discipline to take 50% profit (don't get greedy) and honor 200% stop (don't get scared)
When it fails
- Crisis regime (VIX > 25) where realized vol beats implied vol
- Holding through 21 DTE — gamma dominates and P&L becomes binary
- Chasing higher premium by moving strikes closer — you're just taking more risk without more edge
General trading rules that apply
Regardless of the specific setup, these apply to every strategy on this site:
- Never risk more than 2% of your account on a single trade
- Place a hard stop-loss before entering — no exceptions
- Journal every trade: setup, reason, outcome, one lesson
- After two consecutive losses, stop for the session
- Backtest and paper-trade for a month before deploying real capital
