Pips and lots

A pip is a standard way to describe a small price movement, while a lot describes trade size. Together they help traders compare movement and calculate how much money may be gained or lost.

A shop may change a price by a few coins. A currency pair can change by a tiny fraction of its quoted price. Traders need a convenient way to describe that move, but a small-looking change in a quote does not mean a small cash result. The position size matters too.

Some screens show an extra decimal place. On EUR/USD, a move from 1.10000 to 1.10001 is one tenth of a conventional pip, sometimes called a pipette. A different screen may display a smaller increment for a different pair or instrument.

If the account is in a different currency, the platform may convert the result. If the pair does not have USD as its quote currency, this simple USD calculation does not apply directly.

To go long EUR/USD is to take a position that benefits, before costs, when the euro rises relative to the dollar. To go short EUR/USD is to take the opposite direction; it can benefit when the pair falls, but a rise can create a loss. A short position is still risky, and its product rules matter. Neither direction is a prediction.

For 10,000 units of EUR/USD, a move of one conventional 0.0001 pip is 10,000 EUR × 0.0001 USD/EUR = US$1 before costs. At 100,000 euro units, the same move is US$10. In USD/JPY, a conventional pip is often 0.01 yen per dollar: 10,000 dollar units × ¥0.01/USD = ¥100 per pip. If your account is in a different currency, convert that yen or dollar result at an appropriate rate. Contract sizes, pip conventions and fractional “pipettes” vary, so confirm the instrument specification.

A lot describes the exposure, not the cash you deposited. Margin is the amount required to support a leveraged position. Planned risk is an estimate of loss under stated price and execution assumptions. These quantities answer different questions and should not be treated as interchangeable.

For example, 10,000 EUR units and a ten-pip EUR/USD adverse movement imply about US$10 of price-move loss before other costs. That does not tell you the margin requirement. Nor does it guarantee a stop order limits the final loss to exactly that amount: a gap or different fill can change it.

In Pip Value Calculator, choose EUR/USD, 0.1 lots, and USD as the account currency. Under its 100,000-unit contract convention, that is 10,000 EUR units and US$1 per pip. Change only the lots to 0.01: the estimate becomes US$0.10 per pip.

For a yen example, choose USD/JPY, 0.1 lots, and a JPY account: the estimate is ¥100 per pip. If you instead use a USD account and manually assume USD/JPY 150, enter 1 ÷ 150, approximately 0.006666667 USD per JPY, as the conversion rate. The result is about US$0.67 per pip. The conversion assumption matters.

In Profit-and-Loss Calculator, choose Long, EUR/USD, 0.1 lots, USD account, entry 1.1002, and exit 1.1012. The gross estimate is US$10. Use entry ask and exit bid for a long; use entry bid and exit ask for a short. The tool estimates the price-move result, not every fee.
