Definition
Daily level for a market index or benchmark (e.g. VIX, SPX) from hydrated index price data — not a tradable equity price.
Parameters
Metric (ticker key: VIX, SPX, NDX, DJI, …)
Output range: Unbounded (index points)
Example condition
`VIX < 20` (Lower volatility regime)Usage notes
Hydrate `indices.index_price_data` and run full cache rehydration so backtests have the binary cache.
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.
