Sizing an Exness order is four numbers taken in a fixed order: volume in lots, contract size from the symbol specification, required margin, then pip value. Required margin equals lot size multiplied by contract size multiplied by price, divided by the leverage on the account. Pip value on most USD pairs is about $10 per pip on a standard lot of 100,000 units and about $0.10 on a 0.01 lot. Compare the result against free margin, not against the balance.

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:

InstrumentContract sizeTick value (USD)Min lotMax lotAvg daily range
EUR/USD100,000$1.000.0120042.5 pips
GBP/USD100,000$1.000.0120050.5 pips

USD/CAD100,000$0.720.0120059.6 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.

Four numbers, in the order they are needed

Why the order of the numbers matters

Margin and pip value answer two different questions and are easy to confuse. Margin answers whether the order can be opened at all. Pip value answers what it will cost if the price moves against it. An order can pass the margin check comfortably and still be far too large once the stop-loss distance is converted into money.

Running them in this order also makes the stop-loss a calculation rather than a guess. With pip value known, the distance to the stop is a number in currency, and the volume can be adjusted until that number is the one intended before the order is ever sent.

Where to confirm the figure

Exness provides a margin, pip and swap calculator inside the Personal Area and on its website, and this site carries interactive calculators built on measured contract specifications. All of them are estimates until the order window is open.

The figure that decides the trade is the one the platform displays at the moment of confirmation, because it uses the live price and the leverage actually applied to that account. Treat every number worked out beforehand as the plan and that one as the fact.

The pre-order margin check

  1. Write down the volume in lots first. Every other number in the check is scaled from it.
  2. Open the symbol specification and read the contract size. It is what turns lots into units, and it differs between instruments.
  3. Work the margin: lot size multiplied by contract size multiplied by price, divided by leverage. A 0.10 lot of EUR/USD at 1.10 needs about $110 at 1:100 and about $22 at 1:500.
  4. Work the pip value for the same volume, so the stop-loss distance can be converted into money before it is placed.
  5. Read free margin in the terminal, not balance. An open position has already committed part of the account, and floating loss reduces what is left.
  6. Open the order window and confirm the margin figure it shows. That is the number the server applies, and it is the one that decides whether the order is accepted.

Higher leverage lowers the margin needed to open the same position. It does not lower the risk the position carries.

Questions that come up mid-way

In which order should the numbers be worked out?
Volume, then contract size from the specification, then required margin, then pip value. Margin decides whether the order opens; pip value decides what it costs when the price moves.
How is the required margin calculated?
Lot size multiplied by contract size multiplied by price, divided by the leverage on the account. A 0.10 lot of EUR/USD at 1.10 needs about $110 at 1:100 or about $22 at 1:500.
Balance or free margin - which one is the check against?
Free margin. Balance ignores what open positions have already committed and what floating loss has taken away, so it will pass orders that the server then rejects.
Does the platform figure ever differ from the calculation?
It can, because the platform uses the live price and the leverage actually applied to that account. The figure in the order window is the one the server acts on.
