1. What is Yahoo Data Average?

The Yahoo Data Average (Moving Average) is a technical analysis tool that smooths out price data by creating a constantly updated average price. This helps identify trends by filtering out the "noise" from random short-term price fluctuations.

2. How Does the Calculator Work?

The calculator uses the simple moving average (SMA) formula:

Where:

• \( ClosePrice_i \) — The closing price at day i
• \( n \) — The number of periods in the moving average

Explanation: The moving average is calculated by adding the closing prices for the number of time periods and then dividing this total by the number of time periods.

3. Importance of Moving Averages

Details: Moving averages are fundamental tools in technical analysis used to identify trends, determine support and resistance levels, and generate trading signals.

4. Using the Calculator

Tips: Enter comma-separated closing prices (most recent last) and select the period length (e.g., 20 for 20-day MA). The calculator will compute the most recent moving average.

5. Frequently Asked Questions (FAQ)

Q4: Why use Yahoo Finance data?
