A Practice Account as a Test of the Machine — Lesotho

A practice account is also a load test: it puts a full set of charts and a live quote stream on the computer you actually own, and lets you watch what that computer does with them.

The usual reason given for a practice account is the strategy. There is a second one that is easier to settle and rarely gets done: it is a cost-free way to find out what the computer in front of you does when a full workspace is loaded onto it. Open charts until it stutters, note the number, and the working ceiling of that machine is known.

What a practice account tells you about the computer

The account is free of charge and the machine is not, so the sensible order is to find out what the machine does under a full workspace while nothing depends on the answer.

When the machine has answered the question

The exercise ends with a number: how many charts this computer holds without complaint, and which of them it holds comfortably. A workspace built to that number behaves the same afterwards, whichever account it is later pointed at, and it is far easier to arrive at the number now than to discover it later.

Why this is worth doing before anything depends on it

A machine near its limit does not announce it. It gets slightly slower, then noticeably slower, and the moment it becomes obvious is usually a busy one. Finding the ceiling deliberately, on a quiet afternoon, turns that into a known number instead of a surprise.

It also costs nothing to run. Nothing has to be arranged, nothing has to be justified afterwards, and the whole thing takes the time it takes to open ten charts and scroll them.

What the number is actually for

A layout should be built to what the machine holds, not to what somebody else's screenshot shows. Once the ceiling is known, the workspace can be arranged to sit comfortably under it, saved as a template, and reopened in one step for as long as that computer is in use.

It also tells you which upgrade would help, if any. If the stutter arrives as charts are added, the limit is the machine; if it arrives only when indicators are added to existing charts, the limit is the workspace and it costs nothing to fix.

A short load test, and what each part of it tells you

What to tryWhat to watchWhat it tells you
Open charts one at a time, up to tenThe point where scrolling begins to stutterThe working ceiling of this machine
Add indicators to each of the open chartsWhether the delay grows with each additionWhether the load is the charts or what is drawn on them
Open a symbol nobody has opened here beforeHow long the bars take to appearHow much of the wait is fetching rather than drawing
Close the program and open it againWhether the arrangement returns intactWhether the profile is being written properly
Leave it running for a full working dayWhether it is still responsive by the eveningWhether memory is being given back as windows close

Each step is reversible and none of them needs a plan. The output is a number of charts, which is the only figure the exercise is trying to produce.

Frequently asked questions

Can a practice account show whether a computer is fast enough?
That is the one thing it settles cleanly. Open charts one at a time until scrolling stutters, and the number reached is the working ceiling of that machine.
How many charts is too many?
There is no fixed number — it depends on the machine and on what is drawn on the charts. The signal is behavioural: when closing a few charts restores smooth scrolling, the ceiling has been found.
Does the same test say anything about a handset?
Very little. A handset is limited by screen space long before it is limited by memory, so the useful test there counts taps rather than charts.
Should the test be repeated after adding indicators?
Yes, and separately. If the delay appears as charts are added the limit is the machine; if it appears only as indicators are added the limit is the workspace.
What does the restart step check?
Whether the arrangement of windows is being written to the profile and read back correctly on this machine. If it is not, that is worth knowing before a workspace is built on top of it.

Disappearing Demo Accounts. the fact that a Demo account gets deleted because you haven’t been on it in a week or less is just weird, I’ve lost about 5 accounts in total I’ve been practicing on, such a shame I actually liked the UI & everything else
