Markets, explained

Our charting workspace. Look at any coin, stock, ETF, index or commodity we cover on one full-size chart, draw on it, and keep your favourites in a watchlist beside it. Which assets it covers, where the prices come from, how the timeframes and the log scale work, and what a chart of past prices can and cannot tell you.

01

What is Markets?

It is our charting workspace. Pick any coin, stock, ETF, index or commodity we cover and see its price history on one full-size chart, with drawing tools, a fullscreen mode and a watchlist for the assets you follow.

It is the one place on the site where crypto and traditional markets share a chart, so you can move from Bitcoin to an index to a fund without changing tools. Today the chart shows price only, with nothing layered on top, so you are drawing on a clean view of the asset.

02

Which assets it covers

The asset box searches the top coins by market cap, and a fixed list of about 160 traditional tickers: roughly 90 stocks, 65 ETFs, a handful of indices and two commodities. That list leans toward companies and funds tied to crypto, AI, power and mining, such as crypto ETFs, miners and treasury companies.

It is a chosen list, not the whole stock market.

03

Where the prices come from

Crypto prices come from CoinGecko. Stocks, ETFs, indices and commodities come from Marketstack and update once a day. That is why both kinds of asset load the same way in the same chart.

Traditional prices are adjusted closing prices at the end of each market day. They are not live quotes.

04

Timeframes

The data is daily. 1D shows every day. The 3D, 1W, 2W and 1M buttons plot one daily close roughly every 3, 7, 14 or 30 days. That smooths out the day-to-day movement so the larger shape is easier to see.

These views are a thinner version of the daily series, not a summary of each period, so they do not show a period’s high or low.

05

Log scale, and why it is the default

On a linear scale, equal distances on the vertical axis are equal dollar amounts. An asset that has risen a hundredfold squashes its early years into a flat line along the bottom, and the detail of those years is lost.

On a log scale, equal distances are equal percentage moves. A fall of half takes the same height in any year, so every era stays readable and different periods can be compared. You can switch between the two with the Lin and Log buttons.

06

Drawing tools and the watchlist

The chart has the full drawing toolbar: lines, channels, zones, notes and measurements, saved per coin so your markings stay with the asset you drew them on.

Open the fullscreen view and the watchlist docks on the right. Keep your favourite coins and tickers there, group them into named sections, reorder them, and click one to switch the chart to it. Optional columns add things like a risk score, a rank and a seven-day sparkline. The watchlist lives on this page only.

07

How to read it

Compare eras on the log scale. A move of the same size in percentage terms looks the same height whether it happened early or late, which makes it fair to put two periods next to each other.

Step between timeframes. The coarser views show the shape of the larger trend. Daily shows a recent move up close. Both describe the past, not what comes next.

08

What the chart does not tell you

A single clean line feels complete, which is when it is easiest to over-read. Five things to keep in view.

It shows price and nothing else

There is no volume, no indicator and no model on this chart, on purpose. A price line cannot say why a move happened, who was trading, or how much money was behind it.

The weekly and monthly views are thinned, not summarised

Those views show one daily close every few days, not a candle with a high, a low and a close. A sharp move that began and ended between two plotted days does not appear on the coarser views.

Crypto and stocks run on different clocks

Crypto trades every day, so its line has a point for every date. Stocks, ETFs and indices only trade on market days, so their lines skip weekends and holidays. Put side by side, they are not sampled the same way.

The traditional list is fixed

Markets covers the top coins and a chosen list of about 160 tickers, mostly connected to crypto, AI, power and mining. It is not every stock. A ticker that is delisted, renamed or loses data coverage stops updating, and its line simply ends.

Stock prices are adjusted and end of day

Traditional prices are adjusted closing prices, updated once a day after the market closes. They can differ from the price a chart showed on a past day, and they are not live quotes.

A price chart shows what happened. It cannot show why, or what comes next.

A record of past prices, not a forecast

Where it fits

This is the charting tool in the Tools section, available on Plus and above. It is a workspace for looking at and marking up prices, and it is not an input to either Heatmeter. The model-based charts elsewhere on the site layer risk, cycles or on-chain data on top of price; Markets is the plain canvas.

More is on the way for this workspace: indicator panes beneath the chart, with our own indicators alongside the main ones, and macro charts. They are not in the tool yet, and this guide will be updated when they are.

Common questions

What is the Markets tool?

Our charting workspace. You pick a coin, stock, ETF, index or commodity from a searchable list and see its daily closing price over its full history, on a logarithmic scale by default. You can draw on the chart, and open a fullscreen view with a watchlist of your favourite assets docked beside it. It is a view of past prices, and it does not feed either Heatmeter.

Which assets can I chart?

The top coins from CoinGecko, plus a fixed list of roughly 160 tickers: about 90 stocks, about 65 ETFs, a handful of indices and two commodities. The traditional list leans toward companies and funds connected to crypto, AI, power and mining, such as crypto ETFs, miners and treasury companies.

Where do the prices come from?

Crypto prices come from CoinGecko. Stocks, ETFs, indices and commodities come from Marketstack and update once a day, so both kinds of asset load the same way in the same chart.

Why is the chart on a log scale?

Crypto assets can move across several orders of magnitude over their life. On a linear scale the early years flatten into a line along the bottom and the detail disappears. On a log scale the same percentage move takes the same height wherever it happens, so every era stays readable and different periods can be compared. You can switch to a linear scale at any time.

What do the 3D, 1W, 2W and 1M buttons do?

They change how often a point is plotted. The data is daily, and these views show one daily close roughly every 3, 7, 14 or 30 days. That smooths out day-to-day movement, but it is a thinner version of the same daily series, not a summary of each period.

Are the prices live?

Not for stocks, ETFs, indices and commodities: those are end-of-day closes, updated once a day. Crypto history comes from CoinGecko and includes the most recent day as it stands.

Is this a buy or sell signal?

No. It describes what an asset's price has done. Patterns in past prices have shown up before, but they are historical observations and not a guide to what happens next.
