Introduction
The Gann HiLo Activator is a trend-following indicator that can help traders identify the direction of the market and enter trades accordingly. It was developed by Robert Krausz and published in his book “W. D. Gann Treasure Discovered: Simple Trading Plans for Stocks & Commodities”. In this article, we will try and understand how the Gann HiLo Activator works and how to use it in trading.
The Gann HiLo Activator indicator consists of a simple moving average and a modified moving average. The simple moving average acts as a support or resistance level, while the modified moving average acts as a signal line. When the price is above the signal line, it indicates a bullish trend, and when it is below the signal line, it indicates a bearish trend.
The indicator is constructed based on a simple moving average of the previous three periods’ highs or lows, depending on the trend direction. When the price is above the Gann HiLo Activator, it implies the security is in an uptrend, and the indicator is computed based on the previous three lows. Conversely, when the price is below the Gann HiLo Activator, it implies the security is in a downtrend, and the indicator is computed based on the previous three highs.
How to use the Gann HiLo Activator

The Gann HiLo Activator can be used to generate entry and exit signals based on the trend direction and the price action. Here are some basic rules for trading with this indicator:
Identify and follow trend
The basic rule of using the Gann HiLo Activator is to follow the trend indicated by the position of the price relative to the indicator line. If the price is above the Gann HiLo line, it means that the trend is up, and you should look for buying opportunities. If the price is below the Gann HiLo line, it means that the trend is down, and you should look for selling opportunities. You can also look at the direction of the signal line. If the signal line is moving upward, it indicates a bullish trend, and if it is moving downward, it indicates a bearish trend.
Crossovers
One way to generate entry signals with the Gann HiLo Activator is to wait for a candle to close on the opposite side of the indicator line, indicating a trend reversal. For example, if the price was below the Gann HiLo line and then closes above it, it signals a bullish reversal, and you can enter a long position. Conversely, if the price was above the Gann HiLo line and then closes below it, it signals a bearish reversal, and you can enter a short position. You can use this information to enter or exit trades, depending on your trading strategy.
Use in conjunction with other tools
Another way to generate entry signals with the Gann HiLo Activator is to use it in conjunction with other indicators or tools, such as oscillators, chart patterns, or candlestick patterns. For example, you can use an oscillator like Relative Strength Index (RSI) or the Moving Average Convergence Divergence (MACD) or Stochastic to identify overbought or oversold conditions in the market, and then use the Gann HiLo Activator to confirm the trend direction and enter a trade in alignment with it.
By combining other indicators, traders can gain a better understanding of market trends and potential trade opportunities. Alternatively, you can use chart patterns like triangles or flags to identify breakout points in the market, and then use the Gann HiLo Activator to filter out false breakouts and enter a trade in the direction of the breakout.
Use as a trailing stop and an entry signal
The Gann HiLo Activator can also be used as a trailing stop and an entry signal. As a trailing stop, it helps traders protect their profits and stay in the trend as long as possible. As an entry signal, it helps traders catch the trend reversals and enter trades in the direction of the new trend.
To use the Gann HiLo Activator as a trailing stop, traders can place their stop-loss order below the indicator in an uptrend or above the indicator in a downtrend. This way, they can lock in some profits and exit the trade when the trend changes. The stop-loss order can be placed below the indicator and moved up as the price rises. When the price breaks below the indicator, it signals a trend reversal and a possible exit point.
Conversely, the stop-loss order can be placed above the indicator and moved down as the price declines. When the price breaks above the indicator, it signals a trend reversal and a possible entry point.

Therefore, it is advisable to use the Gann HiLo Activator with caution and discretion, and always combine it with other indicators or tools to confirm its signals and filter out noise. It is also important to use proper risk management techniques when trading with any indicator, such as setting stop-losses, trailing stops, and take-profits according to your trading plan and objectives.
