What is the 80 Rule in Trading?
The 80 rule in trading is a concept used primarily in market profile analysis, indicating that if the market opens outside of the previous day’s value area and then moves back into it, there’s an 80% chance it will traverse the entire value area. This rule helps traders identify potential price movements and make informed trading decisions.
Understanding the 80 Rule in Trading
What is Market Profile?
Market profile is a charting technique that displays price and volume data over a specific period. It helps traders understand market sentiment and identify key levels of support and resistance. The market profile organizes price data into a distribution curve, highlighting where the majority of trading activity occurs.
How Does the 80 Rule Work?
The 80 rule is based on the idea that if the market opens outside the previous day’s value area and then returns to it, there’s a high likelihood it will move through the entire value area. The value area is the price range where 70% of the previous day’s trading occurred.
- Opening Outside the Value Area: When the market opens outside the prior day’s value area, it may indicate a shift in market sentiment.
- Reentering the Value Area: If the market reenters the value area, it suggests that the initial sentiment shift may not be sustained.
- Traversing the Value Area: The 80 rule posits that there’s an 80% chance the price will move through the entire value area, offering potential trading opportunities.
Practical Example of the 80 Rule
Consider a scenario where the previous day’s value area ranges from $100 to $110. If the market opens at $95 (outside the value area) and then rises back to $101, traders might anticipate that the price will continue to $110, leveraging the 80 rule to make trading decisions.
