+/// The Median indicator is particularly useful in financial analysis for:
+/// - Providing a robust measure of central tendency that is less affected by extreme values than the mean.
+/// - Identifying the middle value in a dataset, which can be helpful in understanding price distributions.
+/// - Serving as a basis for other indicators or trading strategies that require a stable reference point.
+///
+/// Unlike the mean, the median is not influenced by extreme outliers, making it valuable
+/// in markets with occasional large price swings or in the presence of data anomalies.
