VIXnD¶

Using the discovery endpoints discussed in the Workflow section, let's investigate some data from the VIXnD set.

# VIXnD.
metric = "vixnd"
# S&P 500 index.
ticker = "SPXW"
# 2026-01-30 21:00:00 UTC, CBOE closing time.
expiry = "1769806800"
# 2026-01-26 17:39:32 UTC
measurement_time = "1769449172"

# Get the data from Reflex Research.
data = get_measurement(
    metric,
    ticker,
    expiry,
    measurement_time,
)

# Visual check of data.
print(data)

# Print the value represented as a percentage.
print(data["payload"]["data"])

The printed result is:

{'vixnd': 15.548}

VIXnD is the annualised standard deviation of returns over the next n days as implied by option prices, representing the volatility the market is currently pricing for that forward horizon.
