United Arab Emirates — Working Out Lot Size From the Amount at Stake — on an Exness Account

Volume is an output, not a preference. The amount to be put at stake is decided first, the distance to the point where the idea is wrong is measured second, and the number of lots is what falls out of dividing one by the other. Standard, Cent, Pro, Raw Spread and Zero accounts all run the same arithmetic on MT4, MT5, the Exness Terminal and the Trade app — only the lot step and the instrument change. Terms can change, so check the current details before you trade.

Position sizing runs backwards from the usual instinct. The starting point is not how much to buy but how much to put at stake, stated as an amount in the account currency. The second input is the distance from the entry to the price at which the idea is simply wrong, measured in points of that instrument. The third is what one lot of that instrument is worth per point. Divide the amount by the distance multiplied by the per-point value and the result is the volume — a number that was never chosen, only calculated. Everything that makes the answer feel uncomfortable is information: if the figure comes out below the smallest volume the account allows, the amount at stake is too small for that distance, and either the distance or the instrument has to change.

Exness — the short version on sizing

Exness has run since 2008, and for this particular arithmetic three details matter. Standard and Standard Cent accounts open with no minimum initial deposit, so the amount at stake is not forced upwards by an entry requirement. Cent-sized lots make the volume step small enough that the calculated figure can actually be used rather than rounded past. Negative balance protection limits losses to the funds deposited. Independent accounts of how this works out in practice sit in the Exness reviews on Trustpilot. CFDs carry a high risk of losing money — confirm the latest terms before depositing.

Three inputs, and where each one actually comes from

The amount at stake is a decision about the account, not about the trade. It is set once, as a figure or as a fraction of the balance, and it does not move because a particular setup looks convincing — the whole point of fixing it in advance is that conviction is exactly the thing it is meant to be independent of.

The distance is a property of the chart, not of the wallet. It is the gap between the entry and the level that would mean the reasoning was wrong, and it has to be measured before the volume is known, otherwise the two get chosen together and the arithmetic becomes circular. Typical daily range is the sanity check here: a distance far tighter than an instrument's ordinary movement is not a tight risk, it is a short wait until the position is closed by noise.

The per-point value is a property of the instrument and the contract size. It is the reason the same amount at stake produces very different volumes on a major currency pair, on gold and on an index: one point of each is worth a different sum, so the divisor changes even when the other two inputs do not.

What the arithmetic looks like end to end

Take an amount at stake of 100 units of account currency and a distance of 25 points. That allows 4 units of currency per point. If one lot of the instrument is worth 10 units per point, the volume is 0.4 lots; if one lot is worth 100 units per point, the same inputs give 0.04 lots. Nothing about the trader's opinion entered the calculation at any stage, which is the property that makes it worth doing.

Now widen the distance to 100 points and hold the amount at stake constant. The allowance per point falls to 1 unit, and the volume falls with it, to a quarter of what it was. This is the relationship that surprises people: a wider stop does not mean more risk, it means less volume for the same risk. Risk is the amount, and it was fixed before either of the other numbers was known.

Finally, round the result down to the volume step the account supports, never up. Rounding up quietly increases the amount at stake past the figure that was supposed to be fixed, and it does so by an arbitrary percentage that depends only on where the calculated number happened to fall. On cent-sized lots the step is small enough that this rounding costs almost nothing; at full lot sizes it can be the difference between the plan and something rather more expensive.

Where the calculated figure meets the account

Two separate checks run on the same volume, and they answer different questions. Sizing asks how much is at stake if the idea is wrong; the margin requirement asks whether the account can carry the position at all. A volume can pass the first and fail the second, and passing the second says nothing whatsoever about the first — a position the account can afford to open is not the same as a position it can afford to be wrong about.

Correlated positions break the arithmetic quietly. Two trades sized correctly on their own but moving together are, in practice, one trade at double the amount, and nothing in the per-position calculation notices. The fix is to size the group rather than the entry, treating instruments that move together as a single line in the plan.

The last check is arithmetic rather than judgement: total the amounts at stake across everything open. If a fixed amount per trade was the plan, this number should be predictable at any moment. If it is not, the position sizes are not being calculated — they are being chosen and then justified. Trading is high-risk; use only money you can afford to lose.

From an amount to a volume, in six moves

  1. Fix the amount to be put at stake on this trade, in account currency, before looking at the chart.
  2. Mark the price at which the reasoning would be wrong, and measure the distance from the entry in points.
  3. Compare that distance with the instrument's ordinary daily range — if it is a small fraction of it, widen it or leave the trade.
  4. Find what one lot of that instrument is worth per point; on a currency pair, gold and an index the three figures are not close.
  5. Divide the amount by distance multiplied by per-point value; the result is the volume in lots.
  6. Round down to the volume step the account supports, then confirm separately that the margin required for that volume is available.

Indicative arithmetic. Per-point values depend on the instrument, the contract size and the account currency; the lot size calculator on this site works from live specifications.

Frequently asked questions

Which comes first, the volume or the stop distance?
The distance. It is measured on the chart from the entry to the level that would mean the idea was wrong. Choosing the volume first and then placing the stop wherever the loss looks acceptable inverts the whole calculation and makes the amount at stake a consequence of a guess.
How is the number of lots actually calculated?
Divide the amount to be put at stake by the distance in points multiplied by what one lot is worth per point. The result is the volume, rounded down to the smallest step the account supports.
Does a wider stop mean more risk?
No, it means less volume for the same risk. The amount at stake is fixed first; widening the distance reduces the allowance per point, and the calculated volume falls in proportion. Risk is the amount, not the distance.
Why does the same amount give a different volume on gold and on a currency pair?
Because one point of each is worth a different sum per lot. The per-point value is the divisor in the calculation, so an instrument with a heavier point produces a smaller volume from identical inputs.
What if the calculated volume is below the smallest the account allows?
That is a real answer, not a rounding problem: the amount at stake is too small for that distance on that instrument. The options are a shorter distance, a different instrument, or an account tier with a finer volume step, such as one trading cent-sized lots.
Should the calculated volume be rounded up or down?
Down, always. Rounding up increases the amount at stake beyond the figure that was fixed in advance, by an amount that depends on nothing more than where the calculation happened to land.
Is the margin requirement part of position sizing?
No, it is a separate check run afterwards. Sizing answers how much is lost if the idea is wrong; the margin requirement answers whether the account can hold the position at all. A volume can satisfy one and not the other.
How should two positions that move together be sized?
As one. Instruments that track each other produce a combined outcome the per-position arithmetic does not see, so the amount at stake should be set for the group and then divided between the entries.
Does the account currency change the calculation?
It changes the units, not the method. The amount at stake and the per-point value have to be expressed in the same currency; the account base currency is chosen when the account is opened, from the options offered on the sign-up form.
