Basics
Liquidity
How easily an asset can be bought or sold without significantly affecting its price. EUR/USD is highly liquid — tight spreads, instant fills, little slippage; exotic pairs and low-volume crypto are not.
In practice
On EUR/USD during the London–New York overlap you can trade 5 standard lots with a 0.2-pip spread and near-zero slippage. The same size on an exotic like USD/ZAR can move the price several pips against you on entry alone, with a spread measured in tens of pips.
Why it matters for traders
Liquidity is the hidden cost and the hidden safety of a market. In liquid conditions your stop fills where you expect and your costs stay predictable; in thin markets, slippage and wide spreads can turn a calculated risk into a much larger loss. Beginners are far safer learning in the most liquid pairs.
Common pitfall
The pitfall is taking a thin, exotic pair for its 'big moves' without pricing in the wide spread and slippage that come with illiquidity. A pair that jumps 200 pips can cost you 20 pips just to enter and exit, and your stop can gap through on a quiet hour. Beginners should learn on the majors, where spreads are tight and fills are honest, and leave exotics until position sizing and cost analysis are second nature.
