News Radar: crypto news events on a price chart

News Radar is a chart that answers one question: what was going on in the news when the price moved? It draws the price line for an asset and marks the important news events on the date they happened.

Each event is a dot. A green dot is a bullish event, a red dot is a bearish one. The dot carries a short title, a write-up and a source. Below the chart you also get a list of the latest market news articles, so the history and today's headlines sit on one page.

It is built for context. Seeing that a big regulation story landed in the middle of a drop helps you remember why the market felt the way it did. It does not tell you what comes next.

Three things on each dot matter: the colour, the impact score and the category. Colour tells you whether the event was good or bad news for the market. The impact score runs from 5 to 10, where a higher number means a bigger event. Events below 5 are not shown at all.

Events that land close together are grouped into one cluster dot, so the chart does not turn into a wall of dots. How close is close depends on how much of the chart you are looking at: the more history is in view, the wider the grouping window gets. Zoomed in, only events a few days apart merge. A cluster can mix bullish and bearish news when you are viewing all news.

You can switch the chart metric between Impact (how big the events are) and Event count (how many there are). The sentiment filter lets you show all news, only bullish events or only bearish events.

The events come from two places. A curated list of historical events is built into the tool. On top of that, an automated review runs once a day at 07:15 UTC. An AI model reads recent articles from our news feed, scores them and only keeps the ones that reach impact 7 or higher. Only events that pass this review are added to the chart, and the page shows when events were last reviewed.

The price line comes from CoinGecko, which supplies the daily price history, with a backup source for some long Bitcoin history. The same events are drawn over every asset you pick. They are market-wide news, not news filtered per coin. Besides Bitcoin and Ethereum you can overlay market totals, dominance lines, baskets such as memecoins or DeFi, and the Fear & Greed Index.

Because part of the scoring is automated, impact scores and the bullish or bearish label are judgements, not measurements. Read the write-up behind a dot before leaning on it.

Above the chart, the bullish and bearish groups each show what the price did on average 24 hours, 7 days and 30 days after their events. Next to them sits the baseline drift: what the price did on an average day across the whole loaded history, with or without news. Comparing the two shows whether event days looked different from normal days.

A small chip at the top shows how closely news sentiment and the following 7-day price move lined up. It is labelled weak, moderate or strong and appears once there are at least 3 matched events. The tooltip shows how many events it is based on. More events give a more reliable read. With fewer than 5 events in a group, the averages are replaced by a note that there are too few events.

Smoothing is a separate option. Raw shows the price as it is. 7D avg and 30D avg replace each day with an average of the days around it, which calms the line and makes bigger swings easier to see.

Keep these in mind before you read anything into a dot.

A made-up example. You open Bitcoin and spot a red cluster with a high impact score during a long drop. You click it, read the write-ups and see that two regulation stories and one security story landed in the same fortnight. That gives you a picture of why sentiment was so poor at the time.

You then look at the bullish group average against the baseline and note that the sample is small, so you do not read much into it. For another angle on market mood, you could read our guide on DCA during extreme fear. News Radar helped you understand the period. It did not tell you what to do.

This explainer is free to read for everyone. In the app, free members get the Bitcoin chart with the full price history and all event dots. Dots and write-ups for the last 365 days are readable. Older dots still show on the chart, but their write-up is locked. Smoothing, the metric switch and the sentiment filter are free too, and so is the Bitcoin news list below the chart.

Premium unlocks the other assets, indexes and baskets, the range picker (90d, 1y, 2y, 3y, 5y and All), the impact and category filters, the readable write-ups on older events, and the news articles from all categories. See pricing for what is included today.
