Holidays and Thin Liquidity
On holidays the currency market usually does not close — it becomes thin. That is more dangerous than closing: the chart keeps drawing, quotes keep coming, and the market's familiar properties no longer hold.
What a thin market is
Liquidity is created by participants. When the largest of them are away, there are fewer opposing orders and the same size trade moves price further. Externally it looks like an ordinary chart, but the mechanics behind it differ: the spread is wider, slippage is larger, and moves occur on volumes that would pass unnoticed on a normal day.
The thinnest periods
Late December and early January, when both Europe and the United States are closed. National holidays in large countries, especially American ones. Long Asian holidays, which noticeably affect the yen and the Australian dollar. A separate case is days when one centre is closed and another is working: the market is not empty but lopsided, and moves in the currencies of the absent centre behave unusually.
Why thin is more dangerous than calm
A calm market means low amplitude with normal liquidity, and it can be traded. A thin market means low liquidity that does not prevent amplitude: a move can be large, it simply arrives without cause and disappears the same way. Technical levels work worse on such days because the usual volume of participants is not standing behind them.
How to change your approach
The simplest solution is to reduce size or skip such days, and most often that is the right one. If you keep trading, widen stops to match the degraded execution, avoid trading level breakouts, and do not carry large positions through long weekends when a gap on the open is possible.

Frequently asked questions
Does forex trade on holidays?
Usually yes, but with sharply reduced liquidity. The market is formally open while few large participants are present, so spreads are wider and execution is worse.
Which periods are the thinnest?
Late December and early January, American national holidays and long Asian holidays. A separate category is days when one financial centre is closed while another works.
Why do levels work worse on holidays?
Because the reaction at a level is created by the volume of participants. With large participants absent, a level has no support and price passes through without the usual resistance.
