One fetch, then no line at all
Exness calculator on a scarce line: loaded once, answering afterwards
The useful property of this page has nothing to do with arithmetic: once it has arrived, it stops asking the connection for anything. Required margin, pip value, spread cost, position size and both overnight swaps are worked out where the page is already sitting, with the bars gone. The figures behind it — spreads and contract specifications from Exness's own MT5 (Standard) feed — came down with the page, and the date they were measured on is printed in the panel header.
Trading calculator
Fill it in during the quiet, not during the window
Volume is entered in lots — a standard trade size, and on forex pairs one lot is 100,000 units of the base currency. The list holds 23 measured instruments, including forex majors and crosses, gold and silver, oil, BTC/USD and ETH/USD, and equity index CFDs, which track an asset's price without owning the asset. All 23 arrived together, so switching between them costs nothing on the line — and neither does changing the volume or the leverage ratio.
Three outputs are worth writing down first. Required margin says how much of the balance the position ties up; spread cost says what crossing the gap between buy and sell takes out of it at the measured moment; pip value says what each step of price movement is worth afterwards. Position size and the two swap lines for holding past the daily rollover can be re-derived whenever this page loads again.
Calculations use spreads and contract specs from Exness's own MT5 (Standard) feed, measured in the trading terminal (2026-08-24). Figures are indicative — spreads may fluctuate and actual results will vary.
Read by what it costs
What one fetch brings, and what is never fetched again
The panel and its instrument table are part of the document. They are not requested when a calculation runs, and no calculation afterwards sends anything back over the connection — there is no lookup, no submission and no quiet refresh in the background. Sorted by what the line actually pays for, the page splits cleanly.
| Costs the connection | Costs nothing once loaded | |
|---|---|---|
| Opening the page | One fetch, including the instrument table | — |
| Choosing a different instrument | — | All 23 are already here |
| Changing the volume or the ratio | — | Recalculated in place |
| Reading margin, pips, spread cost, swaps | — | Nothing is requested to produce them |
| Reloading the page | The whole fetch again, from the start | — |
| Getting a fresher measurement | A reload — the snapshot arrives with the page | — |
| Placing the order this was sizing | A live terminal session and a steady link | — |

Two rows in the left-hand column are the same event. Freshness and a reload are one purchase, which is why it is worth knowing what a reload actually costs before reaching for it.
The expensive reflex
Refreshing is the move that costs something
A reload pulls the whole document down again and empties every field on the way. On a line that is charged by the megabyte or that takes a minute to deliver a page, that is the difference between one visit and several — and the entries that were typed are gone before the replacement arrives. It is worth filling the panel in once, in one sitting, rather than treating it as somewhere to return to.
Four habits that turn one fetch into three
- Pulling down to refresh out of habit. Nothing on this page updates by itself, so a refresh buys a newer snapshot and loses the inputs — a fair trade only when the date in the header genuinely matters.
- Navigating away to check a definition, then coming back. Going back may re-fetch; reading the notes under the panel first is cheaper.
- Closing the tab before the numbers are recorded. Nothing is saved; the page has no memory between visits.
- Waiting for a spinner that will never resolve. If the outputs read as dashes, the inputs are empty rather than the connection being slow.
Where the good minutes go
Sizes decided while the line is down, orders sent while it holds
A weak connection is rarely uniformly weak — it comes in usable stretches. The practical arrangement is to spend those stretches on the things that genuinely need them and to do everything else in between. Sizing belongs firmly in the "in between" category.
Settle it offline
Instrument, volume in lots and leverage ratio can all be decided with no link at all, provided this page is already open. Nothing about that decision needs the market to be reachable.
Spend the window on sending and closing
Placing an order, amending a level and closing a position are the actions that must reach the trading server. They are also short, which is what makes them fit into a good stretch.
Choose the route by what it repeats
An installed terminal downloads once and then carries a price stream; a browser terminal fetches its interface every session. On a costly line the difference compounds. Routes sorted by what they repeat →
Rehearse where nothing is lost
A demo account behaves the same way over the same line and costs nothing to interrupt. Trading is risky and may not be suitable for everyone. Demo account guide →
After the tab is gone
Keeping the answer, and knowing how fast it ages
A dropped session takes the page with it. Three figures written down survive that, and they are enough to work from until the next time the page can be fetched: the required margin, the pip value and the spread cost. Copied out with the instrument, the volume and the ratio beside them, they can be checked against a terminal later without loading anything again.
Worth recording alongside them: the date in the panel header. On a USD account, 0.01 lot of EUR/USD is 1,000 units of the base currency — about $1,143 at the measured mid rate of 1.14349 — which asks about $5.72 of margin at 1:200, makes one pip worth about $0.10, and costs about $0.08 to cross at the measured 0.8-pip spread. Margin and pip value are arithmetic and do not age; they follow from contract size, volume and leverage. Spread cost is the line that ages, because spreads fluctuate and widen around news and around the open and close.
Figures are indicative, taken from spreads and contract specifications from Exness's own MT5 (Standard) feed on the date shown in the panel. Actual results will vary, and the quote in the terminal at the moment an order is placed is the one that counts.
Quick answers
Asked with the panel loaded and the connection gone
Does the calculator work with no connection at all?
Once the page has loaded, yes. The instrument table and the arithmetic are part of the document, so every output continues to respond to the inputs with nothing reachable.
Is anything sent back when a calculation runs?
No. Changing an instrument, a volume or a leverage ratio produces a new row without any request leaving the page.
How much does a reload cost?
The whole page again, including the instrument table, and every field returns to its starting value. The only thing gained is a newer measurement, when a newer one exists.
How stale can the numbers get before they mislead?
The margin, the position size and the pip value follow from contract terms and do not decay. The spread cost tracks a fluctuating quote, so it is the line to treat as indicative once the measurement date is no longer recent. Swap rates are updated by the broker.
Which figures are worth writing down before the line drops?
Required margin, pip value and spread cost, together with the instrument, the volume in lots, the ratio used and the measurement date. That is enough to rebuild the reasoning later without the page.
Can an order be placed from this page?
No. Sizing happens here; sending happens in a terminal signed in to a trading account, which does need the connection. The account type behind the cost line is chosen when the account is opened. Account types in detail →
The sizing is free; the account needs one steady stretch
Registration is the part of this that genuinely wants an uninterrupted connection, and it is short: an email address and a brief questionnaire on the official Exness website, then identity verification in the Personal Area, where the leverage setting also lives.
