# Glossary

**Alpha wallet**: a wallet at the head of the follow graph. Others have been observed buying after it. See [Alpha](/platform/alpha.md).

**Avg lag**: the typical delay between a leading wallet's buy and its followers'. Long lag is tradeable room; short lag is not.

**Band**: a range shown instead of an exact figure (for example a balance or PnL band). Ranges are ordered correctly, so sorting still works.

**Buy pressure**: buys against sells from tracked wallets. Well above 50% is accumulation; well below is distribution.

**Cluster**: holders linked to each other by shared funding, direct transfers or same-block buys. Likely one person or one coordinated group. See [Clusters](/concepts/clusters.md).

**Confidence (low / medium / high)**: how much evidence stands behind a signal verdict.

**Dump risk**: a calibrated probability that a token dumps, shown next to the signal verdict.

**Elite first buy**: an S or A tier wallet was among the very first buyers of a token.

**FOMO volume**: volume from swaps by tracked wallets. Not market volume.

**Fresh wallet**: a wallet with little or no history before this token.

**Hot**: the top band of the signal percentile, 80 and up. Bands: Quiet <30, Weak 30-54, Strong 55-79, Hot 80+.

**KOL**: a public figure whose calls move attention. Tracked separately from their wallets, because what they say and what they hold are different data.

**Milestone PnL**: profit booked at the milestone a trade is ranked on, not necessarily at the wallet's final exit.

**Position closed**: the wallet held this token and sold out. Its PnL is realized.

**Realized PnL**: profit actually booked on closed trades, as opposed to paper gains on a bag still held.

**Received, not bought**: the position arrived by transfer or allocation, so there is no purchase to compute a return from.

**Signal (percentile)**: a token's smart-money strength relative to other active tokens, 0-100 and directionally neutral. See [Thesis Intelligence](/platform/thesis.md).

**Signal (Tachyo Signal)**: the model verdict on a token, one of ENTER, WATCH, RUNNER, SKIP or OVERHEATED. See [The Tachyo Signal](/concepts/tachyo-signal.md).

**SM / Smart money**: wallets Tachyo scores as having a real track record.

**SM activity**: how recently smart money last traded a token in our feed. Green under 1h, amber under 6h, red beyond.

**Snapshot**: the last recompute of a token's holder census and tiers. A separate clock from live price and from the signal.

**Sniper**: a wallet that bought within moments of a token becoming tradeable.

**Thesis**: a smart-money wallet opening or describing a position in a token, in their own words.

**Tier (S / A / B / C)**: a wallet's quality band, earned from its track record. S is the strongest, C the weakest. See [Wallet tiers](/concepts/wallet-tiers.md).

**Top 100 of**: other tokens where a wallet is a top-100 holder. Cross-token conviction.

**Trend chips**: TREND BUILDING, FRESH CROSS, LOSING STEAM, TREND BROKEN, FALLING KNIFE. A price-structure reading, independent of the verdict.

**Unrated**: not enough closed-trade history to assign a tier. Unmeasured, not bad.

**Unknown**: we tried to measure and failed. Never rendered as a zero.

**Walk-forward / as-of**: testing a score using only what was knowable at the time, then evaluating what happened next. No look-ahead.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tachyo.ai/support/glossary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
