How a EUR/USD lot works
One standard lot of EURUSD is 100,000 euros. The pair is quoted in dollars, so one pip (0.0001) is worth $10 per lot — $1 per mini lot (0.1) and $0.10 per micro lot (0.01) — whatever the exchange rate.
That fixed $10 is why EURUSD is the easiest market to size: lots = risk ÷ (stop in pips × 10). A 20-pip stop risking $100 is 0.50 lots.
Many brokers quote a fifth decimal (a pipette, 0.00001). Ten pipettes make a pip — enter prices as your platform shows them and the calculator does the rest.
