Whether the finite current value strictly exceeds every one of period prior
observations, excluding the current bar. Equality fails. Default propagate
uses prior chronological bars; skip collects prior finite observations.
Missing current values, gaps in required history, and insufficient history
return false. Invalid periods throw RangeError; unknown policies TypeError.
