How to Use Moving Average Envelopes

Babypips Elementary - Grade 4

"What is a Moving Average Envelope (MAE)?

A technical indicator consisting of a moving average plus an upper and lower line plotted at a fixed percentage above and below that moving average.

Why is it called a 'dynamic' support/resistance tool?

Because the envelope lines move continuously with the moving average, adapting to recent price action rather than remaining horizontal.

Which moving-average types can be used to build an MAE?

Any moving average (SMA, EMA, etc.); the chosen MA forms the center line.

How do you calculate the upper envelope of an MAE?

Upper Envelope = Moving Average + (Moving Average × envelope %).

How do you calculate the lower envelope of an MAE?

Lower Envelope = Moving Average − (Moving Average × envelope %).

Give an example of a 10-day SMA with 1 % envelopes.

Upper = 10-SMA + (10-SMA × 0.01); Lower = 10-SMA − (10-SMA × 0.01).

What does it mean if price closes ABOVE the upper envelope?

Bullish signal: possible trend start or continuation upward; potential buy trigger.

What does it mean if price closes BELOW the lower envelope?

Bearish signal: possible trend start or continuation downward; potential sell trigger.

How can MAE confirm trend direction?

If the MA and envelopes slope up, trend is bullish; if they slope down, trend is bearish; if flat, market is directionless.

When is an MAE used to spot overbought levels?

When price rises above the upper envelope while the moving average slope is flat (sideways market).

When is an MAE used to spot oversold levels?

When price drops below the lower envelope while the moving average slope is flat.

What buy signal can be taken in a sideways market using MAE?

Buy if price touches or falls beneath the lower envelope, then rises back above it.

What sell signal can be taken in a sideways market using MAE?

Sell if price touches or rises above the upper envelope, then falls back below it.

What is the main limitation of using MAE for overbought/oversold readings?

In strong trends, price can remain overbought/oversold (outside an envelope) for extended periods.

What envelope percentage is common for daily FX charts?

Typical settings range between 1 % and 2 %, but traders adjust based on volatility and timeframe.

In an MAE, what is the role of the central moving average?

It acts as the baseline trend indicator; envelopes are plotted symmetrically around it.

How does MAE differ from a standard moving average crossover?

MAE uses fixed-percentage bands for dynamic support/resistance, whereas crossovers use interactions of two different moving averages.

When does an MAE generate more reliable breakout signals?

When the moving average has a clear slope (up or down) and price closes beyond the corresponding envelope.

Why should MAE envelope levels be confirmed with horizontal support/resistance?

To filter false signals and increase the probability that a breakout or bounce will hol
