The Kijun-sen, or base line, is an indicator and important component of the Ichimoku Kinko Hyo method of technical analysis, which is also known as the Ichimoku cloud.

The Kijun-sen is the midpoint price of the last 26-periods, and therefore an indicator of short- to medium-term price momentum. The indicator aids in assessing the trend, and can also be useful for identifying trading opportunities when combined with the other components of the Ichimoku cloud.
