Options AI — Nifty & Bank Nifty Trading Models

By Shakti Tiwari · Nifty Options Trader & XGBoost Expert

This is the Options AI research vertical — focused entirely on Nifty 50 and Bank Nifty derivative models. It is a separate, topically-focused property from the main hub, built so Indian index traders get deep, repeatable method instead of tips.

The method is the same five-layer pipeline documented across Shakti Tiwari's research: Data Engine → Feature Engineering → Predictor (XGBoost/LightGBM) → Risk Filter → Executor. Here we go deeper on index-specific behaviour.

Why Nifty & Bank Nifty Need Their Own Models

Nifty 50 and Bank Nifty are not S&P 500. They have different expiry mechanics (weekly expiry, Thursday settlement), different OI concentration, and a retail-heavy participant base that creates repeatable sentiment patterns in the Option Chain. A model trained on US equities transfers poorly. Index-specific features matter.

Index-Specific Feature Set

Predictor Choice for Indian Indices

Both XGBoost and LightGBM work. For index data (larger row counts, more strikes), LightGBM's histogram splits give faster iteration. The predictor outputs P(direction | features) per strike; the filter then decides action.

import lightgbm as lgb
model = lgb.LGBMClassifier(n_estimators=400, learning_rate=0.05,
                          max_depth=5, subsample=0.85, colsample_bytree=0.8)
model.fit(X_train, y_train)

Risk Filter for Index Options

Worked Index Example (Illustrative)

Bank Nifty spot 52,000, ATM 52,000, IV 17%, PCR 0.92, India VIX 14, DTE 6, OI buildup +ve at 52,200 CE. Features: max_pain_distance 0.2%, vix_z −0.3. Predictor P(up)=0.64. Filter: band ✅, DTE ✅, VIX ✅, max_pain 0.2% ❌ (too close to pin) → SIZE REDUCED, not blocked. This nuance is what separates a framework from a signal.
