SimulationA calculation on the figures you entered. A conversion between units of size. The notional value uses the price you typed: it is not a quote. Educational information, not investment advice or a recommendation to trade.

How it works

Formula

units = standard lots × contract size; 1 standard lot = 10 mini lots = 100 micro lots; notional value = units × price

With your numbers

1Units (standard lots × contract size)1 × 100,000 = 100,000
2Mini lots (standard lots × 10)1 × 10 = 10
3Micro lots (standard lots × 100)1 × 100 = 100

Assumptions

A mini lot is a tenth of a standard lot and a micro lot a hundredth. Those two ratios are the convention everywhere; what a standard lot holds is not.
The contract size of a listed instrument is the one in its published contract description. For anything else, type the contract size your own platform’s specification gives: a lot of a metal, an index or a share is not 100,000 of anything.
The notional value is the full value of the position at the price you type, in the currency the price is quoted in. It is not the margin, which is a fraction of it, and it is not the amount at risk.
No price is supplied or fetched by this page. Without a price the conversion still works; only the notional value waits.
Platforms round sizes to their own step, often 0.01 lots, and may refuse a size between steps.

In plain language

A lot is a number of units, and the number depends on the contract.

Sizes are quoted in lots so that a platform and a trader mean the same quantity. For a currency pair one standard lot is 100,000 units of the base currency by convention. A mini lot is a tenth of that and a micro lot a hundredth, so 0.01 lots and one micro lot are the same thing said two ways.

The ratios between standard, mini and micro never change. What a standard lot contains does: a lot of gold is counted in ounces, a lot of a share CFD in shares, and the number differs from one instrument and one broker to another. That is why the contract size is an input here, taken from the published contract description for the instruments this site lists and from your own platform for anything else.

Multiply the units by a price and the result is the notional value: the full value of what the position controls. Margin is a fraction of that figure and profit and loss are calculated on all of it, which is the reason to know it. The page supplies no price; the notional value appears when you type one.
