Moving Average Calculator

Calculate Simple Moving Average (SMA) and Exponential Moving Average (EMA) with custom period windows and trend signals.

Quick Definition & Answer

What is the Moving Average Calculator?

Moving average calculation smoothes historical financial asset price series to identify underlying market trends and filter out short-term price noise. It computes simple, exponential, or weighted averages across specified price intervals, assigning uniform or exponential weightings to recent asset closing prices. This equips technical analysts and algorithmic traders with objective trend indicators to generate trade signals, confirm trend direction, and manage risk.

The Moving Average Calculator smooths financial time-series price data to identify trend direction, support levels, and momentum inflection points using SMA and EMA models.

How to Use the Moving Average Calculator

Follow these 3 simple steps for instant, accurate calculations.

1. Set Window Period (N)

Choose your calculation window length (e.g. 5, 20, 50, or 200 periods).

2. Enter Historical Price Data Points

Input your sequential numerical price series or recent closing prices separated by commas or spaces.

3. Analyze SMA & EMA Trend Metrics

Review the computed Simple Moving Average, Exponential Moving Average, percentage trend deviation, and momentum signals.

Core Moving Average Calculator Inputs & Terminology

Window Period (N)

The number of historical observation intervals used to calculate the rolling smoothed average.

Simple Moving Average (SMA)

The unweighted arithmetic mean of price data over the specified N-period lookback window.

Exponential Moving Average (EMA)

A weighted average that applies exponentially decreasing weights to older price data, placing greater priority on recent observations.

Smoothing Multiplier (alpha)

The weighting factor 2 / (N + 1) used to compute the continuous recursive EMA value.
