Exness Lot Size Calculator - and How Long a Size Stays Current · South Africa
A position size is a reading with a shelf life. The specifications under the calculator carry the date they were captured on, the market moves on while the arithmetic is being done, and an order that has been placed is not yet an order that has been filled. This page covers that time dimension: how long a worked-out size stays current, what ages it, and what each waiting state around it means.
An Exness lot size calculator turns your risk into a position size: enter your account balance, how much you are willing to risk per trade and your stop-loss in pips, and it returns the volume in lots. Sizing your position to your risk is the core of trading risk management. Pro mode sizes in your account currency, checks the margin the size needs and sets the stop from the instrument's measured average daily range; switch to Simple for a quick lots-from-risk figure.

What lot size fits a $1,000 account risking 2%?
Risking 2% of a $1,000 account puts $20 at risk. With a 30-pip stop-loss on EUR/USD, where one pip per lot is worth about $10.00 at measured specs, the size is about 0.07 lots — around 7,000 units, needing about $40.62 of margin at 1:200 leverage.

The capture date is part of the figure
Every specification the tool works from was read at a moment and printed with that moment attached. A reading does not stop being true afterwards; it stops being current, and those are two different failures. Treating the capture date as decoration is how a figure taken in one stretch quietly gets reused in a very different one.
How quickly a reading ages is not constant. Through a calm stretch the same inputs keep returning effectively the same answer for a long while; around a busier one they stop describing the present much sooner. The date says when the reading was taken; only the stretch it was taken in says how fast it drifted afterwards.
That is why the honest word for the output is indicative. It is a measured starting point with a time attached to it, not a figure held open for anyone.
The gap between working it out and the order resting
Between the moment a size is settled and the moment an order actually rests on the server, time passes: reading the result, typing it, confirming it, and the trip to the server. No leg of that is long on its own, and together they are long enough for the ground underneath to have moved.
The size itself does not change in that gap — arithmetic does not go stale by sitting. What changes is what it was computed against. A size worked out in one state of the market and placed in another is not wrong; it is simply older than it looks.
The practical consequence is about order of operations rather than speed: settle every input first and place afterwards, instead of adjusting inputs while an order is half-entered, which restarts the gap without announcing it.
Placed, resting and filled are three different waits
An order that has been sent has finished one wait and begun another. Placed means it reached the server; resting means it is sitting there with conditions that have not been met; filled means the wait ended and the position exists. On a clock the three read nothing alike: the first is short and bounded, the second is open-ended, the third is a single moment.
A resting order can wait through stretches when nothing on it moves at all, including any period when its market is not trading. That stillness is not the order failing — it is the clock the order depends on standing still.
The distinction matters most when a figure is reused. A size worked out for an order that filled straight away and the same size carried over to an order that has been resting since are two different things by the time anyone compares them.
When to recompute instead of reusing
A worked-out size has expiry points rather than a fixed lifetime. The first is the end of the stretch it was computed in. The second is any gap during which its market was closed. The third is any change to the inputs themselves, however small it looked at the time.
Carrying a number across one of those points is where reuse goes wrong, and nothing announces it. The figure looks exactly the same the next morning, which is the whole problem: everything it was measured against had a night in between.
Recomputing costs one pass through the tool. Deciding whether an older figure is still current takes longer than redoing it, which is the entire argument for redoing it.
Keeping a size from quietly going stale
- Read the capture date printed with the measured specifications before reading the result — it is the age of the ground, not the age of the answer.
- Settle every input first and take the output once; changing an input after the number is out restarts the gap between calculation and placement.
- Place while the reading is fresh, or accept that it is not fresh and treat the figure as a starting point rather than a current one.
- Write down which stretch a figure belongs to. A number kept without the moment it came from cannot be judged current or stale later.
- Recompute after any closed stretch instead of carrying the previous figure into the first order of the next one.
- When an order has been resting a long time, recompute before changing anything on it rather than after.
The tool's figures are indicative and come from specifications measured at the date shown beside them; they describe the moment they were captured in and no other.
How long each figure keeps
| The figure | What ages it | When it reads as stale |
|---|---|---|
| A size from settled inputs | Nothing, on its own | Only when an input it used changes |
| The measured specifications behind it | Time and the state of the stretch | Once the capture date is no longer the current stretch |
| An amount converted into another currency | A rate that moves through the day | Sooner than the size itself |
| A size carried across a closed stretch | The gap itself | At the reopening, before the first order |
| A size attached to a resting order | Every stretch the order waits through | Whenever that order is next touched |
Ageing here is about currency, not correctness: a reading stays true for the moment it was taken and stops describing the present one.
What each waiting state means on the clock
| State | Which wait has ended | Which wait is running |
|---|---|---|
| Inputs settled | Deciding | The gap before placement |
| Placed | The trip to the server | The conditions written on the order |
| Resting | Placement | Time, for as long as those conditions take |
| Filled | The order's own wait | Whatever the position does from here |
| Cancelled or expired | All of them | Nothing — starting again needs a fresh reading |
The states describe how time passes around an order; they are not a suggestion to place one.
