The Alligator Indicator for MT4 is one of the most powerful trend-following tools designed to help traders identify high-probability buy and sell signals. Created by Bill Williams, this indicator uses three smoothed moving averages to determine market direction, trend strength, and trend-reversal points. For day traders in Forex, stocks, and commodities, the Alligator Indicator for MT4 offers a structured approach to enter trades confidently, even in unpredictable intraday market conditions.
The indicator consists of three lines—called the Jaws, Teeth, and Lips—each representing a different moving average period. When these lines intertwine, the market is ranging or preparing for a trend. When they spread apart, the Alligator “awakens,” signaling a potential trend-running opportunity. This makes the indicator ideal for filtering false breakouts and capturing strong market movements.
The Alligator is made up of three smoothed moving averages:
Lips (Green) – 5-period Smoothed Moving Average
Teeth (Red) – 8-period Smoothed Moving Average
Jaws (Blue) – 13-period Smoothed Moving Average
These lines shift into the future to predict potential price movement. The arrangement of these lines helps traders identify whether the market is sleeping (range), waking (breakout), or feeding (strong trend).
When all three lines are tightly braided, the market is consolidating. This is a no-trade zone because the probability of false signals is high.
When the three lines begin to separate and point in the same direction, a new trend may be starting. This is often the earliest and most important signal for breakout traders.
As the lines widen, the trend strengthens. Traders can hold positions longer and use trailing stop strategies for bigger profits.
Day trading often comes with increased volatility, uncertainty, and frequent trend reversals. This is where the Alligator becomes highly effective.
A buy signal appears when:
Green Lips crosses above Red Teeth
Red Teeth crosses above Blue Jaws
The price remains above all three lines
All lines point upward and widen gradually
Entry:
Buy immediately after the crossover and candle close.
Stop Loss:
Below the Jaws (13-period MA), which acts as dynamic support.
Take Profit:
When the Lips cross back downward or when candles close inside the moving averages.
A sell signal appears when:
Lips cross below the Teeth
Teeth cross below the Jaws
The price stays under all three lines
All lines slope downward and separate cleanly
Entry:
Sell after confirmation of all three lines turning downward.
Stop Loss:
Place above the Jaws (acting as resistance).
Take Profit:
Exit when the Lips cross upward or when the Alligator lines contract again.
Helps avoid trading in choppy markets
Confirms strong directional moves
Reduces false breakout entries
Works in all intraday timeframes (M5, M15, M30, H1)
Ideal for trend continuation and pullback trading
Works well with other indicators like RSI, MACD, and Momentum Oscillator
Compared to exponential or linear weighted moving averages, the Alligator can filter noise effectively, although it may lag slightly in highly volatile market conditions.
Avoid placing trades when the lines are intertwined
Combine signals with price action (breakouts, trendlines, candlestick patterns)
Monitor higher-timeframe Alligator structure for overall trend direction
Use trailing stops during strong “feeding” phases to maximize profits
Apply support/resistance levels for confirmation and better risk management
The Alligator Indicator for MT4 is a reliable technical analysis tool that helps traders capture profitable trend movements while avoiding low-probability trades. Its unique structure of Jaws, Teeth, and Lips provides deep insight into market behavior, making it ideal for Forex day trading and trend-following strategies. When combined with multi-timeframe analysis and price action confirmation, the Alligator can significantly enhance accuracy and risk-to-reward performance.
