The Alligator indicator, developed by legendary trader Bill Williams, is a popular trend-following tool used to identify market phases such as consolidation, trend initiation, and trend continuation.

While MetaTrader includes the standard Alligator indicator, it does not provide any alert functionality. Traders must constantly monitor charts to detect when the Alligator lines align and signal potential trading opportunities.

The Alligator with Alert Indicator for MT4 & MT5 enhances the original indicator by adding real-time alerts and visual signals, allowing traders to react quickly and trade more efficiently.

What Is the Alligator Indicator?
The Alligator indicator is composed of three smoothed moving averages, each representing a different part of the “Alligator”:

• Jaw – Smoothed Moving Average (period 13, shift 8)
• Teeth – Smoothed Moving Average (period 8, shift 5)
• Lips – Smoothed Moving Average (period 5, shift 3)

These three lines help traders identify whether the market is:

• Sleeping (consolidation)
• Awakening (trend beginning)
• Eating (strong trend in progress)

When the three lines separate and align in one direction, it often signals the start of a trending move.

What Is the Alligator with Alert Indicator?
The Alligator with Alert Indicator for MetaTrader is an enhanced version of the standard Alligator indicator that includes automatic notifications and visual trade signals.

The indicator detects when:

• The Alligator lines align and begin to separate
• The “mouth” of the Alligator opens, signaling a potential trend
• The moving averages cross, generating possible buy or sell signals

When these conditions occur, the indicator notifies the trader instantly.

Key Features
The Alligator with Alert Indicator for MT4 & MT5 offers the following features:

• Standard Bill Williams Alligator calculation
• Automatic detection of line alignment
• Alerts when the Alligator opens its mouth
• Buy and Sell arrows displayed on the chart
• Alerts triggered once per signal to avoid noise
• Works on all timeframes and instruments
• Lightweight and easy to use

Alert Types Supported:

• On-screen alerts

Why Use an Alligator Alert Indicator?
Without alerts, traders must watch charts constantly to catch Alligator signals. With alerts enabled, traders can:

• Save time and reduce screen monitoring
• React faster to new trend opportunities
• Trade multiple instruments simultaneously
• Maintain discipline in trend-following strategies

The indicator can be used in:

• Trend-following strategies
• Trend reversal strategies
• Bill Williams trading systems
• Combination with other indicators such as Fractals, Awesome Oscillator, or RSI

How to Trade with the Alligator Indicator
Typical trading approaches include:

• Trend Entry – Enter trades when the Alligator opens and lines align
• Trend Continuation – Stay in trades while the lines remain separated
• Trend Exit – Consider exiting when lines start converging

The alert system ensures traders are notified exactly when these conditions occur.
