How do I measure the difference between price and moving average?
Chartists can measure the difference between price and a moving average using the Percent Change Tool and the Percentage Price Oscillator (PPO). Knowing how far above or below a stock is from its moving average can help determine if it is overextended or if momentum is accelerating.
What happens to the moving average in a downtrend?
This is because the average acts like a floor (support), so the price bounces up off of it. In a downtrend, a moving average may act as resistance; like a ceiling, the price hits the level and then starts to drop again. The price won't always "respect" the moving average in this way.

What is exponential moving average?
For example, the exponential moving average (EMA) is a type of moving average that gives more weight to more recent trading days.
How to calculate EMA?
To calculate an EMA, you must first compute the simple moving average (SMA) over a particular time period. Next, you must calculate the multiplier for weighting the EMA (referred to as the "smoothing factor"), which typically follows the formula: [2/ (selected time period + 1)].

What is the 50% threshold for stocks?
The 50% threshold works best with the percent of stocks above their longer moving averages, such as the 150-day and 200-day averages. The percent of stocks above their 50-day moving average is more volatile and crosses the 50% threshold more often. This volatility makes it more prone to whipsaws. The chart below shows the S&P 100 %Above 200-day MA ($OEXA200R). The horizontal blue line marks the 50% threshold. Notice how this level acted as support when the S&P 100 was trending higher in 2007 (green arrow). The indicator broke below 50% at the end of 2007 and the 50% level turned into resistance in 2008, which is when the S&P 100 was in a downtrend. The indicator moved back above the 50% threshold in June-July 2009.#N#Even though the percent of stocks above their 200-day SMA is not as volatile as the percent of stocks above their 50-day SMA, the indicator is not immune to whipsaws. In the chart above, there were several crosses in August-September 2007, November-December 2007, May-June 2008 and June-July 2009. These crosses can be reduced by applying a moving average to smooth the indicator. The pink line shows the 20-day SMA of the indicator. Notice how this “smoothed” version crossed the 50% threshold fewer times.

Why Use A Moving Average
Types of Moving Averages
- A moving average can be calculated in different ways. A five-day simple moving average (SMA) adds up the five most recent daily closing pricesand divides the figure by five to create a new average each day. Each average is connected to the next, creating the singular flowing line. Another popular type of moving average is the exponential moving average (EMA). The calculati…
Moving Average Length
- Common moving average lengths are 10, 20, 50, 100, and 200. These lengths can be applied to any chart time frame (one minute, daily, weekly, etc.), depending on the trader's time horizon. The time frame or length you choose for a moving average, also called the "look back period," can play a big role in how effective it is.1 An MA with a short time frame will react much quicker to price c…
MA Disadvantages
- Moving averages are calculated based on historical data and nothing about the calculation is predictive in nature. Therefore, results using moving averages can be random. At times, the market seems to respect MA support/resistance and trade signals, and at other times, it shows these indicators no respect.4 One major problem is that, if the price actionbecomes choppy, the …
The Bottom Line
- A moving average simplifies price data by smoothing it out and creating one flowing line. This makes seeing the trend easier. Exponential moving averages react quicker to price changes than simple moving averages. In some cases, this may be good, and in others, it may cause false signals. Moving averages with a shorter look-back period (20 days, for example) will also respon…

Simple Moving Average
- The calculation for EMA puts more emphasis on the recent data points. Because of this, EMA is considered a weighted averagecalculation. In the figure below, the number of time periods used in each average is identical–15–but the EMA responds more quickly to the changing prices than the SMA. You can also observe in the figure that the EMA has a higher value when the price is rising …
Example of A Moving Average
- The moving average is calculated differently depending on the type: SMA or EMA. Below, we look at a simple moving average (SMA) of a security with the following closing prices over 15 days: 1. Week 1 (5 days): 20, 22, 24, 25, 23 2. Week 2 (5 days): 26, 28, 26, 29, 27 3. Week 3 (5 days): 28, 30, 27, 29, 28 A 10-day moving average would average out the closing pricesfor the first 10 days as …
Example of A Moving Average Indicator
- A Bollinger Band® technical indicator has bands generally placed two standard deviations away from a simple moving average. In general, a move toward the upper band suggests the asset is becoming overbought, while a move close to the lower band suggests the asset is becoming oversold. Since standard deviation is used as a statistical measure of volatility, this indicator adj…
