Coin indices

GET https://data.vike.io/v1/hl-cohorts/symbols/{symbol}/indices

The asset page's Smart Money Index (SMI), Whale-vs-Shrimp Index (WSI) and whale and smart bias for one symbol, as ratios in [−1, +1] — the site multiplies them by 100 for display. latest is the newest 5-minute snapshot; series is the settled hourly rows, newest first. Both are computed with the site's own rung sets and SQL.

What each value is

A long share is long / (long + short) notional of a set of rungs.

smi and smart_bias use the realized-PnL ladder, wsi and whale_bias the account-size ladder; both are on Cohorts and axes. The hourly sets also count the older hours that were stored under the retired spellings of the same rungs. Values are rounded to six decimal places.

A value is null, never 0, when a rung set holds no positions — null says nothing is there, and 0 would read as perfectly balanced. A symbol with no snapshot at all answers with latest.ts and every latest value null.

The response

The window and paging

The window is start as given, or else the hours newest hours at or before end (default 168, max 8760). At most limit rows come back (default and max 5000), so a window over 5000 hours takes two calls; has_more says older rows exist. Page back with end = the oldest ts minus 1 second: end is inclusive, so passing the oldest ts itself repeats that row. A start more than 8760 hours before end (or now, when end is omitted) is a 400.

Errors

Every rung's own hourly positioning on a symbol is on /symbols/{symbol}/cohort-metrics; the point-in-time labels are explained on Label basis.
