ingredients.
The activity index describes observed activity on one venue. It does not rank investment safety, forecast returns or describe all exchanges.
The four inputs.
| Input | Weight | Mapping to 0–100 |
|---|---|---|
| Absolute UTC move | 35% | abs(last / UTC open − 1) / 0.12 × 100 |
| 24h range | 25% | (high / low − 1) / 0.20 × 100 |
| 24h USD turnover | 25% | (log10(max(volume × VWAP, 1)) − 5) / 4 × 100 |
| 24h trade count | 15% | log10(max(trades, 1)) / 5 × 100 |
Each component is clamped to 0–100. Available weighted inputs are summed and divided by their available weight. Coverage shows how much original weight was available. A missing input is not replaced with zero. An index with no inputs is unavailable.
The state has a trigger.
Priority order: Wide spread when bid/ask gap is at least 0.5%. Otherwise Watch when 24h range is at least 12% or absolute UTC move is at least 8%. Otherwise Moving when absolute UTC move is at least 2% or range is at least 5%. Otherwise Quiet. Quiet does not mean safe.
A size check is a snapshot.
The service walks up to 100 returned price levels on Kraken, from best price outward. For a buy it consumes asks; for a sell it consumes bids. Each level contributes min(remaining quantity, available quantity) × price. Reference VWAP is total value / covered quantity. Uncovered quantity remains visible. Slippage compares that average with the best returned price; fees and later changes are excluded. No order is submitted.
Addresses need a chain.
The DEX lookup accepts an explicit supported chain and token address. Only matching base-token pools on that chain are used. Up to 30 returned pools are shown, ordered by reported USD liquidity. Summed liquidity and the largest-pool share describe that returned sample, not the entire network. Unknown liquidity, holders and contract permissions stay unknown. A scan is not a security audit or sellability check.
Robinhood Chain scans only registered stock-token contracts from the issuer registry. Token price equals the raw issuer midpoint multiplied by current shares per token. Supply is read at a fixed chain block. DEX volume and holder distribution are not inferred.
Sources, times and limits.
- Kraken public API: USD spot quotes, 24h fields, OHLC and order-book levels. The UTC open is not a trailing 24h open. The last 15-minute candle can still be open.
- DEX Screener API: token-pair samples with price, liquidity, volume and pair creation time.
- Robinhood Chain: issuer registration and public chain RPC for registered tokens.
Quotes cache for 20 seconds, candles 45 seconds, pool scans 30 seconds and order books 5 seconds. Refresh uses the same bounded caches. Read time is the retrieval time, not an exchange trade timestamp. Provider failure displays a retry state.
Your research stays private.
Stars, up to 20 observations and 30 editable notes are stored on the server under a random browser access key. Anyone with that key can access the workspace. Keep it and a signed backup before clearing browser storage. This is not end-to-end encryption; the server operator can access stored data. Saved observations retain their original source record; saving fetches provider data again. No email recovery.
