# How AlphaEngine alerts are produced

What the system watches, when it sends an alert, what it excludes, what the tiers mean, how we measure results and where the limits are.

## What we watch

New Solana tokens launched on pump.fun, from the moment they are created, using public blockchain data and public market and risk tools.

## What an alert is

A notice that a token is in the final stretch of its [bonding curve](https://getalphaengine.io/en/bonding-curve/) and passes our filters. It carries the curve, market cap, trades, holders, top-10 concentration, the dev's share, the declared links and the contract address. **It is not a buy order**: you check the data and decide. Any term you don't know is in the [glossary](https://getalphaengine.io/en/glossary/).

## What we exclude

- Tokens on our blacklist.
- Copies of another token.
- Tokens with highly concentrated supply or very few holders.
- Tokens with little real activity.

Passing the filters does not make a token safe. Before you put money in, [check its contract](https://getalphaengine.io/en/check-memecoin-contract/).

## Tiers

Every signal has one tier: Élite, Selecto or Radar. The tier describes how many filters the signal passes, **not how much it will rise**. Which tiers each plan receives is on the [memecoin alerts](https://getalphaengine.io/en/memecoins/) page.

## How we measure results

For each alert we compare the market cap at the alert with the highest market cap reached in the following 24 hours. That peak **is not what a member earns**: it usually comes within minutes and nobody sells exactly at the top.

## Limits

- Most alerts do not double their market cap.
- Some tokens die before they have any price history and cannot be measured.
- The data comes from public sources that sometimes fail or arrive late.
- We don't know whether a member buys a token, at what price or when they sell: we don't measure anyone's profit.

## Review

Every week we review the filters against measured results and members' 👍/👎 votes. The criteria for each tier and the number of alerts can change.

## Hours

The system sends alerts every day from 09:00 to 05:00 UTC. Outside those hours no alerts are posted.

## Change log

- **13 Nov 2026.** First version of this page.

**Risk warning.** Memecoins are extremely volatile and you can lose 100% of what you put in. Alerts are information, not investment advice or a recommendation to buy any token, and past results do not guarantee future results.
