Volatility
Also known as: market volatility
Volatility: Volatility is how much and how quickly a currency pair’s price moves over a period. Higher volatility means larger price swings and, for the same position size, greater risk.
What drives volatility
Economic data releases, central bank decisions, political events, shifts in risk sentiment and the time of day all affect how much prices move. Volatility often rises when major sessions overlap and around scheduled news, and it can spike when liquidity is thin.
How it is measured
Traders often look at the average daily range in pips, indicators such as the Average True Range (ATR), or statistical measures of historical volatility. Options markets also price expected, or implied, volatility.
Why it matters
In more volatile conditions, prices travel further in a given time, so stops are often placed further away — which, for the same risk per trade, means a smaller position. Spreads and slippage can also increase.
Example
A pair that moves 150 pips on an average day is more volatile than one that moves 60 pips, so the same 20-pip stop is far more likely to be reached on the first pair.

Liquidity is how easily a currency pair can be bought or sold without moving its price much. Highly liquid pairs tend to have tighter spreads and less slippage.
- Slippage
Slippage is the difference between the price you expect when placing an order and the price at which it is actually filled. It can work against you (negative slippage) or in your favour (positive slippage).
- Stop loss
A stop loss is an order that closes a position automatically if the price moves against you to a set level. It is designed to limit the loss on a trade, but it does not guarantee the exit price.
