What Are Wide-Ranging Days?
Let me explain wide-ranging days to you directly: they describe the price range of a stock on a particularly volatile trading day. These days happen when the high and low prices are much further apart than on a typical day. As a technical analyst, you might identify them using the volatility ratio, which I'll get into later.
Understanding Wide-Ranging Days
Wide-ranging days have a true range that's larger than the surrounding days, and they usually predict a trend reversal. You should note that extreme wide-ranging days signal major trend reversals, while less extreme ones point to minor reversals.
The average true range (ATR) gives you a way to compare the trading range between multiple days by calculating the difference between the current low minus the close of the previous period. The absolute true range for any period is the greatest of the high minus the low for that period, the high minus the previous close, or the previous close minus the current low.
Typically, the ATR is a 14-day exponential moving average (EMA) of the true range, though you can adjust the period based on your trading needs. Remember, an EMA weights the most recent data points more heavily, which is why it's also called an exponentially weighted moving average.
Important Signals from Wide-Ranging Days
Here's something crucial: after a sharp downtrend, a wide-ranging day with a strong close—meaning the close is near the high of the day—is a signal that the trend will reverse upward. On the flip side, after a strong advance, a wide-ranging day with a weak close near the low signals a downside reversal. Keep this in mind when analyzing charts.
Special Considerations for Identification
You can use the volatility ratio to identify wide-ranging days through a technical indicator that automates the process. This makes it easier for you to screen for opportunities without manually combing through charts.
Calculate the volatility ratio by dividing the true range for a given day by the exponential moving average of the true range over a period, usually 14 days. In general, wide-ranging days occur when this ratio exceeds 2.0 over that 14-day period. I recommend incorporating volatility ratios into your stock charts to spot potential reversal opportunities.
To sum it up, wide-ranging days happen when a stock's price range greatly exceeds normal volatility. You measure them with the ATR, and analysis is automated via the volatility ratio. These days usually predict trend reversals, but always confirm them with other technical indicators and chart patterns.
