Methodology
How WhaleRoom tracks smart money
Every figure on WhaleRoom comes from first-party data we collect and score ourselves. Here is exactly what we track, how it is sourced, and how our daily reports are written.
Live whale positions (Hyperliquid)
We continuously monitor the open perpetual positions of large accounts on Hyperliquid, a fully on-chain derivatives exchange where positions are publicly visible. For each tracked account we record side (long/short), notional size, entry, leverage, live PnL and ROI, and liquidation distance. Accounts are ranked by size and by realised performance, and we flag profitable whales — accounts with a positive historical track record — separately from the crowd.
The 17-signal accumulation index
For each coin we compute a single 0–100 accumulation index from a composite of momentum, valuation and flow indicators, including:
- RSI (daily and weekly) and Stochastic RSI
- Bollinger %B and the Money Flow Index (MFI)
- Mayer Multiple (price relative to the 200-day average) and further trend/valuation measures
A reading above ~60 leans toward accumulation; below ~40 leans toward distribution; the middle is neutral. The index is a summary of many signals, not a single indicator, so no one metric dominates the verdict.
24-hour position delta
By comparing tracked positions across a rolling 24-hour window we label each whale as building (adding), trimming (reducing) or new, and aggregate the net dollar change — the “smart money, last 24h” figure you see across the site.
Spot ETF net flows
We track daily US spot Bitcoin and Ethereum ETF net flows, per fund and in aggregate, sourced from Farside Investors. ETF data is reported once per trading day.
How the daily reports are written
Our per-coin pages and the daily News report are generated by an automated data-to-text pipeline: a language model narrates the figures from our own data snapshot into plain English. A numeric-provenance check rejects any number that does not appear verbatim in the underlying data, so the prose can never introduce a figure we did not measure. The reports contain no price targets, forecasts or trading advice — only what the data shows — and are reviewed before publishing.
Update cadence
Whale positions and the accumulation index refresh continuously throughout the day; ETF flows update once per trading day. Each page shows its own “updated” timestamp in UTC.
Data, not financial advice
WhaleRoom is a research and data product. Nothing on the site is financial, investment or trading advice, and none of it is a recommendation to buy or sell any asset. Markets are risky; do your own research.
