The Blast Off Indicator is a technical analysis tool designed by the renowned trader and author, Larry Williams. Developed in 2002, the Blast Off Indicator aims to identify explosive price moves in the market, whether they are to the upside or downside. The name “Blast Off” refers to the indicator’s ability to spot price explosions. The indicator works by measuring the day’s open and close prices, as well as the high and low prices of the day, to determine the trading range. This information is then used to identify potential breakouts, allowing traders to enter positions at the optimal time. In this article, we will take a closer look at the Blast Off Indicator, how it works, and how traders can use it in their trading strategies.
What is the Blast Off Indicator?
The Blast Off Indicator is a technical analysis tool designed to identify potential price explosions in the financial markets. Developed by legendary trader Larry Williams in 2002, this indicator utilizes the day’s open/close and high/low values to measure the range of price movement for a given trading day. Specifically, when the difference between the open and close is less than 20% of the range, it indicates indecision and a probable breakout. This information can be used to predict potential price movements in the market, making the Blast Off Indicator a valuable tool for traders looking to make informed investment decisions.
Blast Off Indicator Strategy
The Blast Off indicator is a trend-following indicator that can be used to identify strong trends in the market. If the BO (Blast Off) line is above 0, it indicates that the trend is bullish and we should look for buying opportunities. On the other hand, if the PO (Pullback) line is below zero, it indicates that the trend is bearish and we should look for selling opportunities.
To trade using this strategy, we need to first identify the trend direction by looking at the Blast Off and Pullback lines. Once we have identified the trend direction, we can then look for entry and exit points based on the above conditions.
It is important to note that this strategy is not foolproof and can result in losses. It is recommended to use proper risk management techniques. Additionally, it is important to backtest the strategy on historical data before using it in real trading.

Conclusion
In conclusion, the Blast Off Indicator is a useful tool for traders who are looking to identify potential price explosions in the market. The indicator compares the day’s open and close values with the high and low values to determine whether a breakout is likely to occur. While the indicator has its benefits, such as providing clear buy and sell signals and helping traders to identify potential breakouts, it also has its limitations, including its reliance on short-term price movements and the potential for false signals. Traders should, therefore, use the indicator in conjunction with other technical and fundamental analysis tools to confirm their trading decisions.
