The dollar is the second currency in the pair (the "quote" currency). That's why the Pip value is a flat $10 per standard lot. No conversion needed.

What moves it

Two central banks sit on either side of this pair.

Money tends to flow toward higher interest rates. So when traders expect the gap between US and euro rates to change, EUR/USD often moves before the banks do anything.

The data that matters most:

Two moves on ECB days. The rate decision is one event. The press conference 30 minutes later is often a second one, because that's where the ECB explains what it might do next.

When it's busiest

EUR/USD is quietest in the Asian session, roughly 7 pm to 2 am ET. It wakes up when London opens around 3 am ET. The busiest stretch is the London–New York overlap, about 8 am to noon ET. After London closes, it often slows down for the US afternoon.

One catch: Europe and the US change their clocks on different dates in March and in late October / early November. For those few weeks, European times shift an hour against ET. Our market hours tool does that math for you.

Its personality

Calm is not the same as safe. It can still move fast on US news at 8:30 am ET.

Reading it with our method

  1. Start on the daily chart. Mark the last few places price clearly turned around. Is it making higher highs and higher lows, or lower ones?
  2. Drop to a smaller chart only in that direction. If the daily trend is up, you only look for buys.
  3. Use the body-close rule. A level only counts as broken when a candle body closes past it. A tail poking through doesn't count.
  4. Set your stop from the chart, then size from the math. Risk a small, fixed slice, like 1%. The lot size calculator turns your stop in pips into a size.

Our multiple timeframe guide shows step 1 and 2 in more detail.

How much is 1 pip on EUR/USD?

$10 on a standard lot (100,000 euros), $1 on a mini lot and $0.10 on a micro lot. It stays fixed because the dollar is the quote currency.
