EUR/USD Profile: The Benchmark Pair and How It Behaves
EUR/USD is the most traded currency pair in the world, and it sets the tone for many others. Its deep liquidity means tight spreads, orderly price action, and fewer random spikes than smaller pairs.
Its drivers are the relative policies of the Federal Reserve and the European Central Bank, growth and inflation differences between the United States and the eurozone, and broad risk sentiment. Because the euro makes up more than half of the dollar index, the pair is largely the mirror image of dollar strength.
Behavior varies by session. Asian hours are usually quiet, with narrow ranges. The London open often brings the first real move, and the overlap with New York contains US data releases, which can move the pair dozens of pips in minutes.
Typical daily ranges have often fallen somewhere between 50 and 100 pips, though they expand during volatile periods and shrink in quiet ones. Check the current average true range instead of relying on a number from memory.
Because so many traders watch it, technical levels on EUR/USD, such as round numbers and prior swing points, tend to attract attention and reactions.
For newer traders, it is a sensible first pair, since costs are low and behavior is relatively clean.
Practical step: record the daily range of EUR/USD for twenty sessions and calculate your own average, then compare with the stop sizes you use.

Re: EUR/USD Profile: The Benchmark Pair and How It Behaves
Because it's more than half the dollar index, I check DXY before I look at EURUSD at all. If the dollar is ripping across every pair, my euro read barely matters that day. A quick way to do it is to pull up GBPUSD, AUDUSD and USDJPY next to EURUSD. If they're all moving the same way against the dollar, the euro chart is mostly a dollar chart and you should trade it like one, with the US calendar in mind. If EURUSD is the odd one out, something euro specific is going on, maybe ECB comments or eurozone data, and that's when the euro side really deserves your attention.

Re: EUR/USD Profile: The Benchmark Pair and How It Behaves
One thing worth knowing for scalping: the first hour after the London open and the hour around US data are where most of the daily range tends to happen. Outside those windows the pair can crawl, and tight targets just sit there while the spread and your patience slowly bleed. From Lagos that means roughly 8am to 9am during BST, and then 1:30pm when a lot of the big US numbers land. Outside those windows I'd either widen the target and hold longer, or not trade at all. Trying to scalp EURUSD in the quiet early afternoon or the late New York session is mostly a way of paying spread for nothing.
