Definition:

A moving average calculates the average value of a set of data points over a chosen time period. It’s called "moving" because, as new data points are added, the oldest ones are removed, allowing the average to shift over time.

Types of Moving Averages

1. Simple Moving Average (SMA):

This type computes the average of a specific number of past prices—typically closing prices—divided by the number of periods.

Formula:

SMA = (Sum of closing prices over n periods) / n

Example: A 10-day SMA sums the closing prices from the last 10 days and divides by 10.

2. Exponential Moving Average (EMA):

Unlike the SMA, the EMA gives more weight to recent prices, making it more responsive to new information.

Formula:

EMA_today = (Close - EMA_yesterday) × Multiplier + EMA_yesterday

Where:

Multiplier = 2 / (Number of periods + 1)

What Moving Averages Indicate

1. Trend Identification:

An upward-sloping MA suggests a rising trend, while a downward slope may indicate a declining trend.

2. Support and Resistance:

Prices often interact with moving averages, bouncing off them like support in uptrends or resistance in downtrends.

3. Crossovers:

When the price moves above or below a moving average, it could signal a potential trend reversal or continuation.

Trading Strategies with Moving Averages

1. Crossover Techniques:

Golden Cross: A bullish signal where a short-term MA (e.g., 50-day) crosses above a long-term MA (e.g., 200-day).

Death Cross: A bearish signal where the short-term MA crosses below the long-term MA.

2. Price Interaction:

Support in Uptrends: When an asset retraces to a rising MA, it might present a buying opportunity.

Resistance in Downtrends: If the asset touches a declining MA during a pullback, it could be a potential point to sell.

3. Moving Average Envelopes:

These are bands placed at a set percentage above and below a moving average.

Any type of MA (simple, exponential, weighted) can be used.

Example: A 50-day MA with a 5% envelope would generate bands 5% above and below the MA line.

These bands can act as dynamic support and resistance levels.-

Note:

While moving averages are powerful tools, they are not foolproof. It's best to use them alongside other technical indicators and analysis methods to validate trading signals and ensure informed decisions.
