Market liquidity

Updated 2026-09-20

Definition

How easily you can buy or sell without moving the price: it depends on the number of participants ready to trade.

Why it matters

Forex is very liquid, especially during the London-New York overlap. With thin liquidity spreads widen and moves become erratic. In SMC language "liquidity" also means the waiting orders above highs and below lows.

Practical example

At 3 in the morning EUR/USD's spread is higher and moves more erratic than at 3 in the afternoon.
