How to validate
- Validate Settlement separately for index weeklies vs stock options.
- Stress-test with expiry-week and event-week subsets (RBI, budget, results).
- Confirm margin and tail-loss scenarios are logged for short premium books.
- Discard readings polluted by untagged discretionary adjustments.
How to track in TradeLyser
- Tag every leg: structure, DTE, moneyness, and whether Settlement was a primary driver.
- Log planned max loss ₹ on entry for short premium strategies.
- Weekly: list open short ITM/ATM legs before expiry with a written roll/close rule.
- Separate F&O account tags from cash equity for Settlement statistics.
Best practices
- Size Settlement trades with margin headroom for gaps and assignment.
- Prefer defined-risk structures when learning a new options concept.
- Roll or close based on written DTE rules, not convenience.
- Keep weekly index and monthly stock books in separate tags.
Common pitfalls
- Short premium without defined max loss while Settlement risk builds.
- Holding illiquid stock options into expiry without a plan.
- Blending index and stock gamma exposure in one tag.
- Ignoring margin spikes on gap opens.
