An easy way to calculate the “daily” risk in dollars for owning a stock or index
Using ATR is a simple and easy way of determining how many shares you can afford to own and still be able to sleep at night.
According to Investopidia, “J. Welles
Wilder … introduced the world to the indicators known as true range and average
true range as measures of volatility. Although they are used less frequently
than standard indicators by many technicians, these tools can help a technician
enter and exit trades, and should be looked at by all systems traders as a way
to help increase profitability.”
I might add that ATR also helps the average trader to calculate and understand the amount of risk you are taking by holding a given stock or index position.
What Is the Average True Range?
ATR is an actual number that represents a stock's average daily price range movement. "It is the difference between the high and low price on any given day. It reveals information about how volatile a stock is. Large ranges indicate high volatility and small ranges indicate low volatility. The range is measured the same way for options and commodities - high minus low - as they are for stocks."
Here is the link to a page where the ATR is calculated for you. Just plug in the stock or index that you are interested in and it will do the rest, including create a chart for you.
