Linear Regression R2
What Is the Linear Regression R2 Indicator?
If you're a trend trader, you want to trade when price is trending. If you prefer to get in and out of trades more frequently than a trend trader, you'd prefer to trade in a non-trending market.
The Linear Regression R2 (LR-R2) is a moving linear regression that plots the R-squared value of a linear regression over a specified time. It's an oscillator that moves between zero and one. When it's at zero, it indicates a lack of trend and when it's at one, it indicates a strong trend.

LR-R2 can be used with indicators such as the Stochastic Oscillator or the Relative Strength Index (RSI). The chart below adds the Fast Stochastic Oscillator in a separate panel. On the chart, you see that between April 22 and May 1, 2024 the trend strength had declined from 0.8 to 0. After that decline, the LR-R2 started rising, and the %K line of the Fast Stochastic Oscillator crossed over the %D line. In addition, the Fast Stochastic Oscillator moved into overbought territory.
The Linear Regression Forecast indicator was overlaid on the price chart to add additional confirmation. Note that price crossed above the LRF. All three indicators confirm the start of an uptrend, which means you could potentially open a long position in SPY.
