The chart that shows how much really moved
History
The free charts you already know draw the volume of a single market. Here several are queried at once and the chart's volume is the sum of those that responded. That is why the figures on this page do not match those of other sites: it is not that some are wrong, it is that they are looking at different pieces of the same thing.
What you are looking at
The bars above
Each bar is a slice of time: where the price opened, how high it went, how low it went and where it closed. The last one is usually the slice still running, so its numbers can still change. When the market signals that this bar is still open, the chart says so.
The volume below
It is how much was bought and sold in that same slice, adding up the markets that responded. No venue sees the whole market: each sees only what goes through it, and that is why this number does not match that of other sites. Right below are the measured figures and where each data point comes from.
What you can do on top
Sixteen indicators, each with its «what does it mean?», and the same one twice if you want (a 20-period average and a 50-period one). Lines, Fibonacci and rectangles saved per instrument. The Tokyo, London and New York sessions in Lima time, the week's economic data on the axis, comparing with another market and the same one on other intervals. Eight chart types (candles, bars, line, area, baseline, Heikin-Ashi, Renko and three-line break), named workspaces to return to your chart with one tap, and the image ready for WhatsApp or Instagram. And a practice mode with play money that tells you how much you risk in soles. None of this is a buy or sell signal.
Where these prices and this volume come from
This chart does not copy the price from any platform. It builds it from public data from five crypto markets, which your own browser queries directly: Binance, Bybit, OKX, Coinbase and Kraken. Each one publishes its trades for free, and here the five are put together.
Volume is added up. That is why it does not match other sites
Each market sees only what goes through its own house. In a single hour on September 10, 2026, in Bitcoin, Binance recorded 573,34 BTC, Bybit 194,51 and OKX 110,45. It is not the same money counted three times: they are different trades, by different people.
Almost all sites show you the volume of a single market. Here the five are added up, so the number is bigger and closer to what really moved. If you compare with another page and it does not match, this is why.
Price is weighted, not just averaged
The five markets do not quote at exactly the same price. To combine them, a simple average will not do: a market where 5 bitcoins moved cannot weigh the same as one where 500 moved. The price of each candle is a volume-weighted average, meaning each market weighs according to what was actually traded on it.
When a market is missing, we say so
Sometimes one of the five sources does not respond. When that happens, nothing is made up and it is not filled in from the one next to it: the candle is marked as incomplete and below the chart you will see which markets responded and which did not. A candle with three sources is not comparable to one with all five, and presenting them as equal would mislead you through form.
The last candle is almost always open: it has not closed yet and its volume will keep growing. It is also marked, because comparing it with the previous ones is comparing a full hour with half an hour.
Why you will not see forex volume here
In the forex market there is no real volume, and it is not that it is expensive to get: it is that nobody keeps that count. The New York stock exchange is a building with one door, and everyone who buys a stock goes through it, so at the end of the day there is an official number. The forex market has no building and no door: it is thousands of banks and brokers trading among themselves, and each one sees only its own counter.
What other platforms call «volume» on a pair such as euro/dollar is usually tick volume: how many times the price changed, not how much money moved. They are different things. You can check it yourself: if you request the euro/dollar history from a data provider, the volume field comes back as zero.
That is why, for assets that do not publish real volume, this chart does not draw the volume panel and tells you so. We prefer to leave it empty rather than show you a number that does not mean what it seems.
What this costs and what is stored about you
The data is requested by your browser directly from each market, without going through our servers. That has two good consequences: the chart is free for everyone and does not get more expensive however many people use it, and we keep no record of our own of what you look at: those requests do not touch any machine of ours, so there is nothing to store in our database.
What you should know, because you can check it yourself: if you accepted measurement, which pair and which timeframe are queried is recorded anonymously —no name, no account and none of your figures— and it serves to know what is really used and what is unnecessary. If you declined it, those notices do not leave your browser, and you can change your mind whenever you want from the cookie notice. The drawings you make, if you use them, always stay in your own browser and do not travel anywhere; the same goes for your list, your multi-chart layouts, your workspaces and the «on this page» alerts. Only if you create with your account an alert that reaches you even if you close the page do we store it so we can send it to you (the level, the instrument and your device; never your email). The full detail is in the privacy policy.
Forex, indices, commodities and stocks: a single source, and we say so
Since September 2026 the chart also shows currencies (EUR/USD, USD/PEN, USD/MXN…), indices (S&P 500, Nasdaq 100, Dow Jones, DAX), commodities (gold, silver, oil, copper, gas) and stocks (Apple, Tesla, Nvidia…). Those markets do not publish their data for free like crypto exchanges: exchanges charge for live data. That is why here they come from a single source, Yahoo Finance, through an AR4 Mercados server that stores each response for one minute so as not to overload it, and with these truths written on screen:
- There may be a delay. Commodity futures arrive with about ten minutes of delay and stocks, depending on the exchange, up to fifteen. The chart marks it next to the price; it does not hide it.
- There is no combined volume. With a single source there is nothing to add up: for stocks and futures the volume that Yahoo publishes is shown, from that source, and for forex and indices none is shown because a real volume to show does not exist.
- There are no 4-hour candles in these markets: Yahoo does not publish them and they are not manufactured here by adding up others.
The twelve cryptocurrencies continue as always: five markets, combined volume, volume-weighted price, and your browser requesting it directly.
Cryptocurrency data comes from five markets and forex, indices, commodities and stocks data from Yahoo Finance; they may differ between platforms. This page is educational and reference material, not a recommendation to buy or sell.
Frequently asked questions
Why does this chart's volume not match that of other sites?
Because almost all of them draw the volume of ONE market, normally the biggest, and each market sees only the trades that go through it. A measurement from September 10, 2026 on the same one-hour candle of the BTC/USDT pair: Binance recorded 573,34 BTC, Bybit 194,51 and OKX 110,45. No figure is false; each one is true for its own house. Adding up those that responded gets much closer to how much really moved. Markets that do not respond are not estimated or filled in from the neighbor: they are left out and below the chart it says which ones went into the sum.
Where does the data come from and why is it free?
Your own browser requests it, directly from the free public APIs of Binance, Bybit, OKX, Coinbase Exchange and Kraken. It does not go through any AR4 Mercados server, so showing this chart costs us nothing per visit. That is why it is free: without an account, 10 minutes a day (the same as in the AR4 Terminal); with your free account, with no usage limit.
Why does no volume appear for forex?
Because that data does not exist. Currencies are not traded on a central exchange: each broker sees only what goes through its own desk, and nobody publishes the total. What many platforms call volume on a currency pair is actually tick volume, that is, how many times the price changed, not how much money moved. Rather than show a number that looks like money and is not, no volume panel is drawn for those assets and the screen says why.
Is the forex, indices, commodities and stocks data as reliable as the crypto data?
It is true, but it is not the same, and the chart says so. Cryptocurrencies are built from five markets that your browser queries directly, with combined volume. The other markets do not publish their data for free, so it arrives from a single source, Yahoo Finance, through an AR4 Mercados server that stores each response for one minute. It may carry a delay (about ten minutes on commodity futures and up to fifteen on stocks, depending on the exchange), has no combined volume, and for forex and indices no volume is shown because it does not exist. There are also no 4-hour candles for them, because Yahoo does not publish them and they are not manufactured here.
Are the prices real-time?
They are recent data, not the continuous flow of a professional terminal. The chart requests the data again at intervals, not on every movement of your finger, so as not to overload APIs that are public and free. Below the chart the exact time at which they were requested always appears: that time is the truth, not the word now.
What is an unclosed candle and why is it flagged?
The last candle on the chart is usually the slice of time that is still running. Its close, its high, its low and its volume can still change before it ends. When the market indicates that this candle is still open, a notice is shown, because making a decision by reading a half-formed candle is a very common and very expensive mistake.
Does this chart give buy or sell signals?
No. It is a reference tool: it shows price and aggregated volume and nothing more. It does not issue signals, does not predict prices, does not execute trades and does not constitute financial advice. The decision and the risk are always yours.
The chart shows what the markets publish and nothing more: it does not issue signals, does not predict prices and does not execute trades. Before deciding with real money, check the price and conditions at your own broker or exchange, because they may differ from what you see here. Trading with leverage can make you lose all your capital.
