# Keltner Channel

## What is the Keltner Channel and how is it calculated?

The Keltner Channel is a technical analysis indicator that is used to identify trends and determine overbought and oversold conditions. It consists of three lines: a central line, an upper band, and a lower band. The central line is typically a 20-day exponential moving average (EMA) of the security’s price, and the upper and lower bands are typically set a certain number of average true ranges (ATR) above and below the central line.

The formula for calculating the Keltner Channel is as follows:

Central Line = 20-day EMA of the security’s price

Upper Band = Central Line + (ATR * Number of ATRs above the central line)

Lower Band = Central Line – (ATR * Number of ATRs below the central line)

Where “ATR” is the average true range of the security, which is a measure of volatility, and “Number of ATRs” is the number of ATRs above or below the central line.

## There are several ways that the Keltner Channel can be used in an algorithmic trading strategy:

1. Trend identification: The Keltner Channel can be used to identify trends in the security’s price. If the security’s price is consistently above the upper band, it can be taken as a sign of an uptrend. Conversely, if the security’s price is consistently below the lower band, it can be taken as a sign of a downtrend.
2. Overbought/oversold: The Keltner Channel can also be used to identify overbought and oversold conditions. An overbought condition occurs when the security’s price reaches or exceeds the upper band, indicating that the security may be becoming overvalued and that a price reversal may be imminent. An oversold condition occurs when the security’s price falls to or below the lower band, indicating that the security may be undervalued and that a price reversal may be imminent.
3. Breakout trades: The Keltner Channel can be used to identify breakout trades, where the security’s price breaks out of the upper or lower band. A long position can be taken when the security’s price breaks out above the upper band, while a short position can be taken when the security’s price breaks out below the lower band.

It’s important to note that the Keltner Channel should be used in conjunction with other technical analysis tools and fundamental analysis in order to provide a well-rounded view of a security’s market conditions.
