Standard Deviation

Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a set of values. In finance, it is used to measure the risk of an asset by calculating how much its returns deviate from the mean return.

A low standard deviation indicates that the returns are close to the average, while a high standard deviation suggests wide fluctuations. For cryptocurrencies, standard deviation is typically very high, reflecting the volatile nature of the market.

It serves as a core component for calculating volatility, which in turn informs risk management and position sizing. Traders use it to establish confidence intervals for price movements and to define their risk tolerance.

It helps in understanding the likelihood of an asset reaching certain price levels within a given timeframe. By providing a clear numerical value for dispersion, it enables objective comparison between different assets.

It is a fundamental statistical tool for any quantitative approach to trading.
