Volatility (Forex) refers to the uncertainty or risk associated with the size of exchange rate changes. Increased volatility means that the exchange rate could potentially have very big price bracket (the difference between the buying price and selling price). High volatility means that the price of currencies can change rapidly in a short period of time in any direction. On the other hand, lower volatility means that the exchange rate does not change abruptly, but slowly and over a long period of time. Typically, the higher the volatility, the more risky the transaction is in the currency pair. In practice, the term "volatility" usually refers to the standard deviation of change in the value of a financial instrument over a given period of time. It

Volatility for market investors

Volatility is often perceived as a negative thing, because it represents uncertainty and risk. However, this high variability often makes the Forex market transactions become more attractive to investors. For investors using the strategy of "day trading" is an important factor in the possibility of high earnings in volatile markets, as opposed to investing long-term investors. Volatility does not determine the direction of change in course. Only describes the level of fluctuations (changes) the exchange rate. Currency pair, which is more variable, is more likely to increase or decrease in value than a pair of low volatility. For example, a simple "conservative" investment such as a savings account is associated with low volatility. Do not lose 30% per year, but did not gain 30%.

Variability in time

Volatility of the currency pair fluctuates over time. There are periods when prices rise and fall rapidly (high volatility), but at other times can seem very stable (low volatility).
