What is the Raff Regression Channel?
Named after its creator, Gilbert Raff, the Raff Regression Channel is a linear regression tool traders can use to identify trends, track price swings, and anticipate potential support/resistance areas where the price can reverse. Also known simply as the linear regression channel, the tool tends to offer a more adaptive channel than traditional channel indicators.
It consists of a linear regression line in the middle with evenly spaced parallel trend lines above and below it. The gap between the linear regression line and the upper or lower channel line is based on the pullback high or low that is the furthest away from the linear regression line.
Traders can use this tool to track price swings in an uptrend or a downtrend. The trend is up if the channel is pointing upward, with the impulse price swings going up and pullbacks going down. A downward trend reversal happens when the price breaks below the lower channel line and keeps moving down.
Conversely, the trend is downward if the channel is pointing downward, with the impulse price swings moving down and pullbacks going up. An upward trend reversal happens when the price breaks above the upper channel line and keeps moving up.

How does the Raff Regression Channel work in trading?
In trading, the Raff Regression Channel works based on linear regression, which simply means using the least-squares method to find the line of best fit for a price series. This best-fit line forms the middle line in the tool and then evenly spaced parallel trend lines are placed above and below it to form a channel within which most of the price swings move.
The width of the channel is determined by the largest pullback swing as of the time the channel is plotted. As a result, to get an effective price channel where the price swings stay inside the channel, it is important to apply the Raff Regression Channel to only “mature” trends that have had at least two large pullbacks. This way, when the price eventually breaks out of the channel, you will know that the trend is either changing its momentum or direction.
Generally, the tool helps to track price swings in an uptrend or a downtrend, with the upper and lower channel lines working as dynamic resistance and support levels respectively. In an uptrend, the channel is pointing upward, with the impulse price swings going up and pullbacks going down. In this situation, traders look for buy setups when the price pulls back to the lower channel line so they can trade the impulse upswing toward the upper channel line. Sometimes, the price will break out of the upper channel line if the trend gets stronger and the price moves higher with stronger momentum. On the flip side, when the price breaks below the lower channel line and keeps moving down, the uptrend is likely to have reversed, and a downtrend possibly emerges.
Likewise, in a downward, the channel is pointing downward, with the impulse price swings moving down and pullbacks going up. In this situation, traders look for sell setups when the price pulls back to the upper channel line to trade the impulse downswing toward the lower channel line. Sometimes, the price will break below the lower channel line if the downtrend gets stronger and the price falls with stronger momentum. On the other side, when the price breaks above the upper channel line and keeps moving up, the downtrend is likely to have reversed, and an uptrend possibly emerges.
Who created the Raff Regression Channel?
The Raff Regression Channel was created by Gilbert Raff, a renowned American accountant, banker, and financial analyst. Before his death in 2021, Raff had been the chairman of the board of many companies in the American Stock Exchange.
He developed the Raff Regression Channel in 1991 to provide a more flexible and adaptive channel than traditional channel indicators. The tool uses the closing prices over a given lookback period to calculate the linear regression line from where the channel is created by plotting equidistant parallel lines above and below the regression line based on the farthest pullback swing.
What makes the Raff Regression Channel unique?
What makes the Raff Regression Channel unique is that it combines linear regression and the highest or lowest price swing to create a channel on a price chart. So, the channel is based on an existing trend in the chart. This is why it is best used in a trend that is already mature.
By mature, we mean trends that have had at least two large pullbacks that can be used to establish the trendline. Both the trendline and the opposite channel line help define the limits of price swings. The tool helps traders identify trends, track price swings, and anticipate potential support/resistance areas where the price can reverse.
Why is the Raff Regression Channel important in technical analysis?
The Raff Regression Channel is important in technical analysis because it defines the path of price swings in an uptrend or a downtrend so traders can easily see where to look for high-probability swing trades in the trend direction. In an uptrend, traders look for buy setups when the price pulls back to the lower channel line so they can trade the impulse upswing toward the upper channel line. Likewise, in a downtrend, traders look for sell setups when the price pulls back to the upper channel line to trade the impulse downswing toward the lower channel line.
How is the Raff Regression Channel calculated?
The Raff Regression Channel is calculated by using the least square method to find the best-fit line (linear regression line), around which is then placed equidistant trendlines based on the farthest swing low or high. Here are the steps for calculating the Raff Regression channel:
- Choose a lookback period, say 14 periods, and mark the closing price for each bar within that period.
- Compute a linear regression analysis of selected closing prices using the least square method or by tracing it on the chart.
- Look for the farthest swing low if the linear regression line is pointing upward or swing high if the line is pointing downward and place a trendline there parallel to the linear regression line.
- Plot the opposite trendline at an equal distance from the regression line as that of the trendline applied in step 3.
What is the purpose of the Raff Regression Channel?
The purpose of the Raff Regression Channel is to show the path of price swings in a trend, using the dynamic support and resistance levels offered by the tool’s lower and upper channel lines respectively. In an uptrend, the impulse swings move from the lower channel line (support) to the upper line (resistance). So, traders can look for buy setups at the lower line and seek to trade the impulse swing to the upper line.
The opposite is the case in a downtrend where the impulse swings move from the upper channel line (resistance) to the lower line (support). In this case, traders can look for sell setups at the upper line and seek to trade the impulse swing to the lower line.
How can traders use the Raff Regression Channel effectively?
To use the Raff Regression Channel effectively, traders should consider the direction of the trend and ensure they trade only in that direction so that they can capture the impulse swings rather than the pullbacks.
If the trend is to the upside, the impulse swings will move upward, and the lower channel line provides a dynamic support level where to look for buy setups. If the market is trending downward, traders can look for sell setups at the upper line to trade the impulse swing down to the lower line.
What are the key components of the Raff Regression Channel?
The key components of the Raff Regression Channel are as follows:
- The Raff Linear Regression Line: This is a best-fit linear regression line through the price data. It constitutes the middle line of the channel, acting as the equilibrium level or central tendency.
- The Upper Channel Line: This is plotted above the regression line based on the farthest swing high in a downtrend or equal distance from the regression line with the lower channel line in the case of an uptrend. It acts as a dynamic resistance level, where traders can find potential sell setups in a downtrend or take profits from long trades in an uptrend.
- The Lower Channel Line: This is plotted below the regression line based on the farthest swing low in an uptrend or equal distance from the regression line with the upper channel line in the case of a downtrend. It acts as a dynamic support level, where traders can find potential buy setups in an uptrend or cover their short trades in a downtrend.
How does the Raff Regression Channel identify trends?
The Raff Regression Channel identifies trends by slanting in the direction of the trend, which also affects the direction of the impulse and correction price swings. Thus, if the channel is pointing upward, with the impulse price swings going up and correction swings (pullbacks) moving down, there is an uptrend.
Conversely, if the channel is pointing downward, with the impulse price swings going down and correction swings moving up, there is a downtrend.
What timeframes work best with the Raff Regression Channel?
The timeframes that work best with the Raff Regression Channel will depend on your trading style and backtesting results. For instance, if your trading style is day trading, you will carry out your trades on intraday timeframes, such as the hourly, 30-minute, 15-minute, or even the 5-minute timeframe.
To know the timeframes that work best out of these, you will need to backtest your strategy on the various intraday timeframes to find out.
How do you interpret the Raff Regression Channel on a chart?
To interpret the Raff Regression Channel on a chart, you primarily consider the direction of the trend, which is determined by the direction the channel is pointing and how the price swings move.
In an uptrend, the channel slants upward, with the impulse price swings going up and pullbacks going down. The price swings tend to remain within the channel, but sometimes, the price will break out of the upper channel line. This indicates that the trend is getting stronger, with stronger momentum. On the flip side, when the price breaks below the lower channel line and keeps moving down, the market is likely to have reversed to the downside.
In a downtrend, the channel slants downward, with the impulse price swings going down and pullbacks going up. The price swings will tend to remain within the channel, but sometimes, the price will break below the lower channel line. This indicates that the downtrend is getting stronger, with stronger momentum. On the opposite side, when the price breaks above the upper channel line and keeps moving up, the market is likely to have reversed to the upside.
What are the upper and lower lines in the Raff Regression Channel?
The upper and lower lines in the Raff Regression Channel are trendlines that represent the channel’s dynamic resistance and support levels respectively. The upper channel line is plotted above the regression line based on the farthest swing high in a downtrend or an equidistance with the lower channel line from the regression line in the case of an uptrend. It could offer potential sell setups in a downtrend or profit targets for long trades in an uptrend.
The lower channel line is plotted below the regression line based on the farthest swing low in an uptrend or an equidistance from the regression line with the upper channel line in the case of a downtrend. It acts as a dynamic support level, where traders can find potential buy setups in an uptrend or cover their short trades in a downtrend.
How do you plot the Raff Regression Channel in trading software?
To plot the Raff Regression Channel in trading software, you look for the indicator in the indicator section of the trading software. In some software, it will be in the tools section.
Wherever it is, simply double-click and drag it to the chart. Make sure the trend already has at least two large pullbacks so that it doesn’t get redrawn when the main pullback happens.
What are the advantages of using the Raff Regression Channel?
The advantages of using the Raff Regression Channel include:
- The indicator can help you identify the trend
- It makes it easy to track the different price swings
- Its lower and upper channel lines serve as dynamic support and resistance levels respectively
Can the Raff Regression Channel predict market reversals?
Yes, the Raff Regression Channel can help predict market reversals when interpreted correctly. First, the upper and lower channel lines provide dynamic resistance and support levels where the individual price swings could potentially reverse.
Second, when these levels are broken, it could signal a market reversal, depending on the existing trend. In an uptrend, if the price breaks below the lower channel line, there is likely a downward reversal in the market. For a downtrend, if the price breaks above the upper channel line, there is likely an upward market reversal.
How does the Raff Regression Channel help with risk management?
The Raff Regression Channel helps with risk management by showing support and resistance levels beyond which traders can place their stop-loss orders. For a long trade in an uptrend, traders can place their stop loss below the lower channel line.
Likewise, for shorts in a downtrend, traders can place their stop loss above the upper channel line.
What are common mistakes when using the Raff Regression Channel?
The common mistakes when using the Raff Regression Channel include:
- Applying the tool to trends that have not had up to two deep pullbacks
- Not combining it with other forms of market analysis
- Taking mean-reversion trades against the trend direction
How does the Raff Regression Channel compare to other trend channels?
The Raff Regression Channel compares favorably to other trend channels because it uses actual price swing points to plot its primary trendline. Depending on the direction of the trend, it may use the farthest swing low (if there is an uptrend) or swing high (in the case of a downtrend) to plot the primary trendline and then plot the opposite trendline equidistant from the regression line. This is unlike other trend channels that use volatility means to calculate the levels of the upper and lower channel lines.
What markets are best suited for the Raff Regression Channel?
All markets are suited for the Raff Regression Channel since it is based only on price swings on the chart. However, regarding the best market condition for the tool, it works pretty well in nicely trending markets and range-bound markets. But it doesn’t work well if there are too many random walks.
Can the Raff Regression Channel be combined with other indicators?
Yes, the Raff Regression Channel can be combined with other indicators to improve its signals. It is best combined with momentum oscillators, such as the RSI and stochastic, which can show when a price swing is exhausted and an opposite swing is emerging.
Divergence signals from these indicators when the price is at the lower or upper channel line can be a powerful confirmation.
How do you adjust settings for the Raff Regression Channel?
To adjust settings for the Raff Regression Channel, you have to evaluate your trading results from time to time to know when you need to tweak the settings for better performance. After adjusting the settings, you may have to backtest to be sure the new setting offers an edge.
What is the difference between the Raff Regression Channel and the Linear Regression Channel?
There is no difference between the Raff Regression Channel and the Linear Regression Channel. It is named the Raff Regression Channel because it was introduced to the trading community by Gilbert Raff.
Is the Raff Regression Channel reliable in volatile markets?
No, the Raff Regression Channel is not reliable in volatile markets because it does not make use of volatility tools in plotting the upper and lower channel lines, and as such, the width of the channel remains the same regardless of any changes in market volatility.
How can beginners get started with the Raff Regression Channel?
To get started with the Raff Regression Channel, beginners can open a demo account, apply the tool to their charts, and practice as much as they need to learn how the tool works. Then, they can formulate strategies with it.
