How Many Accounts and Windows One Machine Will Hold — Lesotho

Several accounts sit under one login without effort. The ceiling that arrives first is the computer: connected accounts, open windows and saved arrangements all draw on the same memory.

Holding several accounts is not what strains a computer — a list of them is only a list. The cost appears when they are opened: each connected account carries its own stream of quotes and its own set of windows, and each open window carries the bars it is drawing plus every indicator drawn on top of them. The practical ceiling is therefore counted in windows, not in accounts.

Where the memory actually goes

What each open thing holds, and what closing it costs you

What is openWhat it holds while it is openWhat closing it costs
A second account connected in the same terminalIts own quote stream and its own set of windowsA reconnection when it is needed again
Ten charts in one windowLive bars for each symbol, redrawn as quotes arriveThe arrangement, unless it was saved as a template first
Several indicators on each of those chartsA calculation pass per chart on every new barThe drawing only — the underlying prices stay
A profile that restores everything at start-upAll of the above at once, before anything is asked of itHalf a minute of arranging windows by hand
Two terminals running side by sideTwo copies of everything, sharing one processorOne of the two views, until it is opened again

Why the list is cheap and the windows are not

Adding an account to a terminal writes a line in a list. Nothing is fetched, nothing is drawn and nothing is held until that line is opened, which is why a long list on a modest machine causes no trouble at all until the day somebody opens all of it.

Opening is where the arithmetic changes. A connected account subscribes to the symbols it is showing and keeps them updating; that work continues whether or not the window is in front of you. Two accounts open at once is roughly two of everything, and a machine that was comfortable with one can be visibly slower with both.

Indicators multiply, they do not add

One indicator on one chart is trivial. The same indicator placed on eight charts is eight separate calculations repeated on every new bar, and three indicators on those eight charts is twenty-four. This is why a workspace that grew slowly can feel fine on the day each piece was added and heavy a month later.

The useful habit is to keep indicators on the charts actually being read and to leave the rest bare. Removing a drawing removes only the drawing — the prices underneath are untouched and come back the moment it is added again.

Signs the machine has run out

The first symptom is usually not a message but a delay: scrolling a chart stutters, switching between windows takes a beat, and the whole thing recovers if a few charts are closed. Closing charts is a reliable test because it is instant and reversible.

The second symptom belongs to start-up. A profile that restores twenty windows asks for all of that work at once, before the machine has settled, and a computer that copes fine during the day can appear broken for the first minute after it is opened.

Trimming a workspace that has grown heavy

  1. Save the current arrangement as a template first, so nothing has to be remembered by hand.
  2. Close the charts nobody has looked at this week — they cost the same as the ones being read.
  3. Strip indicators from the charts kept for reference only, leaving them on the ones being worked.
  4. Disconnect the accounts that are not in use today; the list keeps them, the memory does not.
  5. Build the start-up profile deliberately, with the smallest arrangement that is still useful.

Everything in this list is reversible: templates restore an arrangement, and a disconnected account is reconnected from the same list it was always in.

Frequently asked questions

Does holding several accounts slow a computer down?
Holding them does not — an account that is only listed costs nothing. Connecting and opening them does, because each open account keeps its own quote stream and its own windows updating.
What is the expensive part: accounts, windows or indicators?
Windows first, indicators second, accounts last. A single account with twenty open charts is heavier than five accounts with one chart each.
How many open charts is too many?
There is no fixed number — it depends on the machine and what is drawn on them. The signal is behavioural: when scrolling begins to stutter and closing a few charts fixes it, that is the ceiling.
Is anything lost by closing a chart?
Only the arrangement, and only if it was not saved as a template first. Prices, positions and account settings are unaffected by what is on screen.
Why is start-up slower than the rest of the day?
A restored profile asks for every window at once before the machine has settled. Building a smaller start-up arrangement and opening extra charts by hand spreads that work out.
