IV Percentile provides insight as to how the current IV for a given term compares to a 1-year history of previous IVs for the same term.
Consider an example 5-day history where the 10d IV has had the following ordered values: 20, 25, 25, 40, 50):
The following represents IV Percentiles for hypothetical “current” 10d IVs:
| 10d IV | Number Of Days Below | IV Percentile |
|---|---|---|
| 20 | 0/5 | 0% |
| 26 | 3/5 | 60% |
| 32 | 3/5 | 60% |
| 38 | 3/5 | 60% |
| 44 | 4/5 | 80% |
| 50 | 4/5 | 80% |
