SIGNAL // OPTION CHAIN INTELLIGENCE
What institutional money
is doing.
In plain English.
Most analysts cannot read option chains. But the signals are incredibly valuable. We translate OI data, IV, PCR, and institutional positions into intelligence anyone can act on.
THE PROBLEM
Options data is the most valuable signal most analysts ignore.
Fundamental analysts spend months building financial models but never look at what the option chain is telling them. Technical analysts read charts but miss the institutional positioning in derivatives.
Option chain data reveals what large institutions are actually doing with their money — not what they say in research reports. But the raw data is impenetrable to anyone without derivatives expertise.
ZenoLattice solves this by translating every option chain signal into plain English that any analyst, fund manager, or investor can understand and act on.

}SIX SIGNAL TYPES
Raw data in. Plain English out.
For each signal type: what the raw data looks like, what it means, and why it matters.
RAW DATA
HDFC Bank 1800 CE: OI jumped from 2L to 48L contracts in 2 sessions.
PLAIN ENGLISH
Someone with deep pockets is betting HDFC Bank crosses Rs 1,800 before expiry. This is 24x normal open interest — likely institutional positioning ahead of results.
WHY IT MATTERS
Unusual OI buildup often precedes large moves. When big money positions aggressively, they usually know something.
RAW DATA
Nifty PCR shifted from 0.78 to 1.42 in 3 days.
PLAIN ENGLISH
Market participants are buying significantly more puts than calls. PCR above 1.2 historically signals either hedging by institutions (bullish) or fear-driven buying (bearish). Context needed.
WHY IT MATTERS
PCR is a contrarian indicator at extremes. Very high PCR often marks bottoms. Very low PCR often marks tops.
RAW DATA
Reliance IV: 18% → 34%. IV rank: 92nd percentile.
PLAIN ENGLISH
The market expects a massive move in Reliance. Current implied volatility is higher than 92% of the past year. Something is expected — results, deal, or event.
WHY IT MATTERS
IV spikes before events. When IV is at extremes without a known catalyst, it often signals information asymmetry.
RAW DATA
Nifty max pain: 22,500. Current: 22,180. 3 days to expiry.
PLAIN ENGLISH
Option writers make the most money if Nifty expires at 22,500. The market tends to gravitate toward max pain as expiry approaches. Short-term upward bias likely.
WHY IT MATTERS
Max pain is where option sellers lose the least. Institutional option writers actively manage positions toward this level.
RAW DATA
Highest call OI: 23,000 CE (1.2 Cr). Highest put OI: 22,000 PE (98L).
PLAIN ENGLISH
The market has drawn a range — 22,000 to 23,000 for Nifty this expiry. Breakout above 23,000 or breakdown below 22,000 would trigger significant gamma moves.
WHY IT MATTERS
High OI levels act as support and resistance. When these levels break, forced hedging by option sellers amplifies the move.
RAW DATA
FII net short 2.4L contracts index futures. DII net long 1.8L contracts.
PLAIN ENGLISH
Foreign institutions are heavily short — betting on downside. Domestic institutions are positioned for upside. This divergence often resolves with a sharp move in either direction.
WHY IT MATTERS
FII positioning reflects global risk appetite. DII positioning reflects domestic flows. When they disagree, volatility follows.
CROSS-SIGNAL INTEGRATION
Options data is just one layer.
When option chain signals combine with other ZenoLattice data, conviction multiplies. Here is what a high-conviction signal looks like:
HIGH CONVICTION SIGNAL
Unusual call buying at 2800 CE — 5x average OI
CFO appeared on CNBC-TV18, revised guidance upward
3 insiders bought shares in last 10 days
No new cases. Existing tax dispute moving toward settlement.
LATTICE VERDICT
STRONG BULLISH — Multiple independent signals converging. Option chain confirms institutional positioning aligned with fundamental catalysts.
