Definition
Constant-maturity at-the-money implied volatility for the underlying, built from the options chain (near-target-DTE expirations, |delta|≈0.50 call/put average, linearly interpolated). Units are annualized decimals (0.25 = 25%).
Parameters
Asset, DTE (target tenor in calendar days)
Output range: > 0 (annualized decimal)
Example condition
`ImpliedVolatility(NVDA, 30) > 0.40` (30-day ATM IV above 40%)Usage notes
Pair with IVRank/IVPercentile for relative richness, or IVHVRatio to compare implied vs realized vol before selling premium.
Use in a strategy
Add this indicator to a strategy condition, choose its supported parameters and compare the output with the threshold required by your rule. Preserve the same interval and lookback when comparing backtests.
After saving the condition, inspect its asset, interval, lookback and comparison operator against the parameters above. If no trades occur, check whether the condition ever became true and whether the requested input data exists for that period. A missing input is not a zero-valued signal. An indicator produces an input to a rule. It does not establish future returns, and data availability can differ across assets and periods.
