Precision-engineered volatility metrics

The only independent at-the-money volatility indexes for equities, fixed income, and bitcoin — built by traders, for traders.

📊
VolDex®
At-the-Money Implied Volatility
The first ATM implied vol index. A consistent, real-time measure of what the market is pricing for near-term moves — without the skew distortion of VIX.

📈
CallDex®
OTM Call Option Cost
Measures the price of out-of-the-money calls over time. Compare across assets to spot when upside is being bid aggressively.
Explore CallDex®
📉
PutDex®
OTM Put Option Cost
Tracks the cost of tail-protection puts. When PutDex® rises sharply, the market is pricing real downside fear — not just elevated vol.
Explore PutDex®
⚖️
RiskDex®
Skew & Sentiment Index
Measures the balance between put and call demand. A neutral, objective lens into directional bias baked into option pricing.
Explore RiskDex®
🦅
TailDex®
Tail-Risk Cost Index
The cost of insuring against extreme market moves. TailDex® rises ahead of crises — even when VIX is complacent.
