<p>Volatility, in the context of Forex and CFD trading, refers to the degree of price fluctuation of a financial instrument over a specific period. It is a measure of the dispersion of returns for a given security or market index. In simple terms, it indicates how much the price of an asset is likely to fluctuate in a given time frame.</p>

<h2>How It Works</h2>
<p>Volatility is typically measured using statistical tools that analyze historical price data. The most common method is to calculate the standard deviation of daily logarithmic returns over a specific period, usually 20 or 60 trading days. This gives an annualized volatility figure, which can then be annualized to give a percentage figure.</p>
<p>There are different types of volatility, including:</p>
<ul>
  <li><strong>Historical Volatility</strong>: Measures the actual price fluctuations of an asset over a specific period.</li>
  <li><strong>Implied Volatility</strong>: Derived from option prices, it reflects market expectations of future volatility.</li>
</ul>

<h2>Why It Matters for Traders</h2>
<p>Volatility is a crucial concept for traders as it influences risk management, strategy selection, and profit potential.</p>
<ul>
  <li><strong>Risk Management</strong>: Higher volatility means increased risk. Traders need to adjust their position sizes and stop-loss levels accordingly to manage risk effectively.</li>
  <li><strong>Strategy Selection</strong>: Different trading strategies perform better in different market conditions. High volatility may favor range trading or scalping strategies, while low volatility may suit trend-following strategies.</li>
  <li><strong>Profit Potential</strong>: High volatility can lead to larger price swings, potentially resulting in higher profits. However, it also increases the risk of significant losses.</li>
</ul>

<h2>Example</h2>
<p>Consider the EUR/USD currency pair. If its historical volatility is 8%, this means that, on average, its price fluctuates by 8% per annum. However, this doesn't mean the price will change by exactly 8% every day. On some days, it might change by more, and on others, by less.</p>
