Exness on a Windows PC: the History Behind a Complete Chart — Lesotho
Bars are fetched, not shipped. A new installation is short of them, a change of timeframe asks for a different set, and the size of the request is far better measured in bars than in minutes.
Open Exness Account →A newly installed terminal shows a short chart, and nothing is wrong with it: the bars have not been fetched yet. History arrives per symbol and per timeframe, on request, and the size of that request is the thing worth knowing.

Why a fresh installation looks empty
A chart is drawn from bars, and bars are downloaded rather than shipped with the program. Opening a symbol for the first time asks for the recent stretch of it; scrolling backwards asks for more, in blocks, as the view reaches the edge of what has already arrived. Until that has happened the chart is short, which is a description of what has been fetched rather than of what exists.
The same symbol on a different timeframe is a separate request. A machine that has filled in one hour bars for a symbol has not thereby filled in the daily ones, which is why a chart that looked complete a moment ago can look short again after a single change of timeframe.
Measuring the wait in volume rather than in the clock
Counting in minutes is unhelpful, because the same download is quick on one connection and slow on another. Counting in volume is stable: a short timeframe holds far more bars for the same stretch of calendar than a long one, so the request behind a one minute chart is a large multiple of the request behind a daily chart covering the same period.
That ratio is the whole planning rule on a connection that is not generous. Filling a long history on a short timeframe, for several symbols at once, is the expensive combination; the same symbols on a longer timeframe are cheap by comparison and usually answer the same question.
What stays on the machine afterwards
Bars that have arrived are written to disk, which is why the second opening of a symbol behaves nothing like the first. The store grows with what has been looked at rather than with what exists, so a machine used for four symbols keeps a modest store and a machine used to browse everything keeps a large one.
It also survives closing the program, so the emptiness of a fresh installation is a one-off rather than a recurring cost. Reinstalling, or moving to another computer, starts the same accumulation again from the beginning — which is the practical argument for doing the filling-in deliberately rather than discovering it in the middle of something.
How Exness runs on a Windows PC
On a desktop PC, Exness runs through the MetaTrader 5 and MetaTrader 4 Windows terminals, which install on Windows 10 and Windows 11. The download links are in the Exness account area once you have signed in.
Desktop app or web on the PC
If you would rather not install a desktop app, the Exness Terminal runs in any browser on the PC with nothing to download. MetaTrader gives more advanced charting and automated trading; the web terminal starts without an install.
MetaTrader 5 & MT4 for Windows
See the MetaTrader 5 and MetaTrader 4 pages for what each desktop terminal does. Using a phone instead? See Android or iPhone & iPad.
