You can understand BEI in a few minutes. The main point is simple: use it as context, not as a buy or sell button.

Quickstart in 60 seconds

  1. Open the dashboard and note whether BEI is above, below, or near 50.
  2. Open Top Narratives or Latest News and read the original source before acting on anything important.
  3. If a story looks important, check whether multiple sources are covering it and whether it looks official, event-driven, or still more like a rumor.

What BEI means

BEI is EchoIndex's live reading of recent Bitcoin-related news. It updates throughout the day and tries to show whether the latest news flow feels more positive, more negative, or mixed.

BEI above 50
Recent news flow is leaning more positive than negative
BEI below 50
Recent news flow is leaning more negative than positive
BEI around 50
The current picture looks mixed or neutral

Where to click

Dashboard

Start here if you want the quickest overview. Daily Sentiment, BEI, Topic Heatmap, Top Narratives, and Latest News tell you what is driving the market right now.

Market

Use Market if you want to compare BEI with BTC price, volume, and volatility over time.

News

Use News when you want to dig deeper. You can filter by time, topic, and sentiment, hide lower-signal items, and open the article details.

Calendar (Coming Soon)

Calendar is planned as a look-back view. It will help you revisit past days, check how BEI moved on each date, and read a compact summary of the main news behind those moves.

How news becomes signal

At a high level, EchoIndex does four things: it collects recent news, analyzes each article, groups repeated coverage together, and then turns that into the live BEI reading.

Step 1: Fetch and analyze articles

Each article is tagged with fields like topic, type, sentiment, Bitcoin relevance, impact, and confidence.

Step 2: Only some story types affect BEI directly

In the current production setup, only stories labeled official_filing, official_announcement, official_ruling, reported_event, developing_event, and unconfirmed directly move BEI. Other article types can still appear on the site, but they are treated more as background context.

Step 3: Deduplicate repeated coverage into events

If many publishers are covering the same story, EchoIndex tries to group them together first. That helps prevent one widely repeated headline from being counted again and again as if it were many different events.

Step 4: Compute Echo Points

Each eligible article gets Echo Points based on how strong the impact looks, how relevant it is to Bitcoin, how confident the model is, and what kind of topic it belongs to.

Step 5: Aggregate into BEI

BEI updates in 5-minute steps. New source confirmation usually matters more than repeated updates from the same source, and older stories gradually matter less over time. The final result is shown on a 0-100 scale, with 50 as the rough neutral line.

Example scenarios

Example A: BEI jumps quickly

  • Check the recent move on the Market page.
  • Open the strongest items in Top Narratives, then compare them with the latest articles in News.
  • Check whether several sources are repeating the same story or whether multiple different stories are moving together.
  • Open at least one original publisher link.

Example B: BEI looks neutral but the market feels chaotic

  • Check whether different topics are pulling in opposite directions, such as ETF optimism offset by regulation worries.
  • Look for lots of lower-signal stories or several clusters pointing in different directions.
