Asset, Lookback period (default 252 days)

Output range: 0–100

Example condition

text

High IV Rank favors premium-selling structures; low IV Rank favors long volatility. Do not confuse with IV Percentile.

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.
