The Figure Before You Open and the Figures After · Tanzania
A calculation describes one moment — the one before a position exists. From the next tick the account reports something else, and the two are not the same number.
Open Exness Account →A margin calculator answers a question about a position that has not been opened. Its answer is tied to the figures that were typed in and to the price of that moment, and nothing keeps it up to date afterwards. Once the position exists the account itself becomes the source: equity, free margin and margin level are recalculated on the broker side with every tick, including while nobody is signed in. An estimate that stops matching is not a broken estimate — it answered a different question.
Measured contract values for your calculations
Read live from Exness’s MT5 Raw+ feed — the contract size, tick value, lot limits and average daily range behind any margin, pip-value, stop-size or profit calculation:
| Instrument | Contract size | Tick value (USD) | Min lot | Max lot | Avg daily range |
|---|---|---|---|---|---|
| EUR/USD | 100,000 | $1.00 | 0.01 | 200 | 47.9 pips |
| GBP/USD | 100,000 | $1.00 | 0.01 | 200 | 60.2 pips |
| AUD/USD | 100,000 | $1.00 | 0.01 | 200 | 41.6 pips |
| USD/CAD | 100,000 | $0.72 | 0.01 | 200 | 49.8 pips |
| USD/JPY | 100,000 | $0.63 | 0.01 | 300 | 155.7 pips |
Tick value is the cash change per minimum price move, per standard lot; the 14-day average daily range helps you size stops and targets. Account stop-out levels (measured): margin call at 60%, stop-out at 0% — confirm the live values in your terminal.
Why a calculated figure stops matching the screen
- A calculator answers a question about a position that does not exist yet, at the price of the moment the question was asked.
- Prices move between the question and the order, so the estimate and the entry are two different moments.
- Once the position exists the account reports its own figures, and nothing keeps the earlier estimate up to date.
- Equity, free margin and margin level are produced on the broker side and keep moving while the screen is closed.
- Opening a second position is a second question; it does not revise the answer given for the first.
- An estimate that no longer matches is not wrong — it answered a different question, at a different moment.
An estimate and a report are different objects
| Calculator | Account screen | |
|---|---|---|
| Describes | A position that does not exist yet | Positions that already exist |
| Valid for | The moment its figures were entered | The current tick |
| Updated by | Asking again | The market, continuously |
| Moves while nobody watches | No | Yes |
| Exists while you are signed out | No | Yes |
An answer with a timestamp on it
Everything a calculator produces is bound to the instant it was produced. It took the figures that were entered, took a price, and returned a result for that combination. The result does not carry any mechanism for noticing that the combination has since changed.
That is not a flaw. A tool for describing a position that does not exist cannot follow a market, because there is nothing yet for the market to act on. The moment the position exists, the job of describing it moves elsewhere.
The account does not consult the calculator
After the order is filled the account starts producing its own figures, and it produces them from live prices rather than from anything that was typed in earlier. No link is kept back to the estimate, and no comparison is made against it.
This is why the two can diverge quietly and legitimately. The estimate is a fixed point; the account is a moving one, and it was already moving during the minutes, hours or weeks when nobody had it on screen.
Which screen to read, and when
Before the order, the calculator is the only thing that can say anything, because the position it describes has no existence anywhere else. After the order, the account is the only honest source, because it is the one being updated.
Returning to the calculator to check on an open position produces a number that looks authoritative and describes nothing. The state of an open position is read where the position is kept.
