A cool little indicator that tells us what a market is ready to blast off, up or down. It allows us to pinpoint specific days when the market will have an explosion of energy.
The logic is simple: Larry Williams compares open and close values with high and low values and if the difference between the daily open and the daily close is smaller than the 20% of the daily range (h-l), it is probable that the next day prices will move widely.In other words, if the absolute value of (open-close)/High-Low is less than 20%, we expect to see a Blast Off.
A Blast Off often comes after a contraction in volatility together with the presence of important technical levels. Surely every trader would prefer to buy before such a Blast Off occurs, and the formula built by Larry Williams can be useful in this sense, helping us in identifying those potential situations where to conduct a more detailed analysis.
