Ranking now favors high OI, positive OI addition, and strikes closer to spot. If OI change is unavailable, use 0 for the last two columns.

How smart ranking works
Supports are ranked from strikes at or below spot using Put OI, Put OI addition, and closeness to spot. Resistances are ranked from strikes at or above spot using the same idea with Call OI.
OI by Strike
Compare Call OI and Put OI visually across the entered strikes.

How to use this Nifty Support/Resistance Finder
- Enter realistic values based on your current plan or trade setup.
- Review the output metrics, not just the headline number.
- Run multiple scenarios to compare best/base/worst cases.
Practical tips
- Validate OI-derived levels with recent swing highs/lows.
- Watch how rankings change after large OI additions or unwinds.
- Treat levels as zones, not exact tick-perfect points.
Model assumptions
- Support/resistance is inferred from OI concentration, OI change, and spot proximity.
- Only provided strikes and spot reference contribute to computed zones.
- Macro/news events can invalidate levels quickly.
Support and resistance levels derived from OI can shift rapidly with intraday positioning changes.
