The Keltner Channel is a technical analysis indicator that is made up of three independent lines that are connected. It consists of a central moving average line, as well as channel lines that are situated above and below the center line.

Keltner The term "channel” describes to a technical analysis indication that is made up of three distinct lines. In addition to a central moving average line, channel lines positioned above and below the central one is included in this equation.
It was called after American grain trader Chester W. Keltner, who described it in his 1960 book, "How to Make Money in Commodities." Keltner was a pioneer in the commodity trading industry.
As a result of revisions, the contemporary version of the indicator employs the exponential moving average (EMA) of the price as the center line.
Keltner Channer Middle Line = EMA
Keltner Channer Upper Band = EMA+2*ATR
Keltner Channer Lower Band = EMA-2*ATR
EMA = Exponential Moving Average(usually over 20 periods)
ATR = Average True Range(range over 10 or 20 Periods)
2 = Multiplier
Keltner channel formula
Choose the asset's holding term, which is normally 20 periods but could be changed before computing the EMA.
Immediately after the selection of the number of periods, calculate the Average True Range (ATR) (usually 20 but may change).
Select the Multiplier to be used for the ATR. This is normally two, although it may be changed if necessary.
To obtain the value of the upper band, multiply the ATR by the multiplier (which is normally two), and then add the resultant value to the EMA to get the value of the lower band.
Using a specified multiplier (usually two), multiply the ATR by that number and remove that value from the moving average to determine the value of the bottom band.
The Keltner Channel is named after after an American trader Chester W. Keltner, who is also credited to have written a book in the 1960 on assets.
Keltner changed his initial version that showed a 10-day moving average and closing prices. He later focused on the central line and the typical price and presented the average of high, low and closing price of the commodities. Keltner Channel remains one of the widely implemented concepts despite it not being implemented in its exact form.
