Technical

High-Low Method

Using the highest and lowest prices over a given period to determine trading range and potential breakout levels.

Definition

The high-low method is a straightforward technical approach that uses the highest high and lowest low over a defined period to establish a trading range. Traders use these levels to identify breakout points, set stop-losses, and gauge volatility. The range width reveals how much a market has moved, while breaks above the high or below the low signal trend continuation or reversal.

How It Works

Identify the highest and lowest prices over a chosen period (previous day, week, month)
These levels form a range that acts as a framework for the current session
Narrow ranges suggest consolidation and a potential breakout; wide ranges suggest an active trend
The method is used in Donchian Channels, which plot the highest high and lowest low over a rolling period

Trading Tips

Mark the previous day's high and low on your chart at the start of each session

A breakout beyond the weekly high or low often signals a trend move

Use the average daily range to set realistic profit targets
