/**
 * Calculate Exponential Moving Average (EMA)
 *
 * EMA is a trend-following indicator that gives more weight to recent prices
 * and responds more quickly to price changes than SMA. It uses exponential
 * smoothing to reduce lag.
 *
 * Formula: EMA = (Price - Previous EMA) * Smoothing Factor + Previous EMA
 * Smoothing Factor = 2 / (Period + 1)
 *
 * @param options - EMA calculation options
 * @returns EMA calculation result
 *
 * @example
 * ```typescript
 * const prices = [10, 12, 11, 13, 14, 12, 15, 16, 14, 13];
 * const result = calculateEMA({ prices, period: 3 });
 * console.log(result.ema); // [10, 11, 10.67, 11.83, 12.92, 12.46, 13.73, 14.87, 14.43, 13.72]
 * ```
