How it works
The volatility range is (high − low) divided by the average rate, showing how much the rate swung during the period. Net change shows the direction and size of the move from start to end. Together they tell you both how choppy the period was and which way it trended.
FAQ
Q. Should I delay exchanging money if risk is high?
A. Not necessarily — when volatility is high, splitting the exchange into several smaller transactions (rather than one lump sum) is the more common way to manage the risk.
