Currency Pairs, Pips, and Lots

A forex price is written as a pair because one currency is valued in terms of another. In EUR/USD, the euro is the base currency and the US dollar is the quote currency.

If EUR/USD is quoted at 1.1000, one euro is valued at 1.10 US dollars. If the quote rises, the euro has strengthened relative to the dollar for that observation. If it falls, the euro has weakened relative to the dollar.

Pips measure movement

A pip is a conventional unit used to describe a change in a forex quote. For many currency pairs, one pip is the fourth decimal place:

• EUR/USD moves from 1.1000 to 1.1001: one pip
• EUR/USD moves from 1.1000 to 1.1050: fifty pips

Pairs containing the Japanese yen are commonly quoted differently, with a pip often represented by the second decimal place. Brokers may also show an extra fractional digit. Always confirm the contract specification rather than assuming every instrument is identical.

Lots measure position size

Lot terminology describes how large a position is. Common labels include:

Label	Typical currency units
Standard lot	100,000
Mini lot	10,000
Micro lot	1,000

These units do not tell you whether the trade is safe. The money gained or lost per pip depends on the pair, position size, account currency, and current exchange rate. Broker calculators can help, but you should still understand what inputs are being used.

Connect movement to risk

Two traders can use the same chart entry and stop price but carry very different risk because their position sizes differ. That is why a setup is incomplete until the monetary loss at the stop has been calculated.

Practice

Using a demo quote, identify the base currency, quote currency, current price, and a hypothetical 20-pip move. Then compare how a micro-lot and a standard-lot position would change exposure. Do not place a live trade for this exercise.

Key takeaway

Pips describe price movement; lots describe position size. Neither should be considered alone when deciding how much money is at risk.
