The trend is seen as down when the shorter moving average is below the longer moving average.EMA Scanner is used to scan the stock market for signals based on the exponential moving averages. A shorter moving average rising above the longer moving average (in the same way that the price going above a moving average) is generally bullish, while a shorter moving average going below the longer moving average is bearish.Īs long as the shorter moving average remains above the longer moving average, the uptrend is considered intact. CrossesĪnother method of confirming a trend is by observing where a shorter (also known as “faster”) moving average is relative to a longer (or “slower”) moving average. During that time frame, the price may have moved significantly. Another challenge with trading based on changes in the slope of moving averages is identifying when that slope definitively changes from being positive to negative or vice versa.Īs seen in the weekly chart above, the slope of a moving average may be close to zero for several weeks. Some longer term bulls may have ignored the 20-week EMA turning down, comforted with the 50-week EMA (the indigo line) and 100-week EMA (the light purple line) still sloping up, suggesting the longer-term uptrend remained intact.Īs with other mathematical indicators, when there is less lag, there is a higher probability of false signals. However, even the 20 week EMA was a lagging indicator, as by the time it had begun sloping down, BTC/USD had already fallen significantly. In the BTC/USD chart above, the most reliable moving average in anticipating the downturn from the beginning of 2018 was the 20-week EMA (the violet line). A generic trading rule is to buy as the moving average begins sloping up, and to sell as the slope of the moving average turns negative. A rising moving average reflects a rising trend, while a falling moving average points to a falling trend. There are 2 Exponential Moving Averages, one fast and one slow. It can also be useful to judge price action momentum or severity by looking at the angle of the 2 EMAs, or the distance between them. Identify trends with moving averages SlopesĪ trader may identify an existing trend through a visual inspection of the moving average. EMA Crossover Strategy A simple EMA cross is a useful indication of a change in direction of a trend and is a very popular tool in trading. The lagging nature of moving averages and their signals make trading off them relatively conservative, as price moves are largely completed by the time a moving average-based trading signal triggers. Since moving averages are customisable, the time frame and the length of the moving average dictate the strength of the signal.īecause of the delayed response to recent price movement, moving averages are known as trend-following indicators. Just like with other indicators, the longer the time frame you are using, the stronger the signal. When the price crosses below the moving average, a sell signal is generated, as the trend is seen as broken to the downside. When the price crosses above the moving average, it is seen as a break above the trend, generating a buy signal. The most common trading signals generated with moving averages when trading cryptocurrency is from watching the interaction between price and the moving average indicator.Ī moving average is a trend indicator and can provide support or resistance. Trend identification using EMA can be more reliable than with SMA as it is more sensitive to recent price changes, although high sensitivity to recent price changes can also result in more false trade signals. EMA vs SMAĪn EMA is a moving average with a different distribution curve that places more weight on recent trading periods.Īs a result, EMAs react faster to sudden changes in price and are especially useful for trading breakouts. For example, if you have a 21 EMA switched on and you are looking at the 1h chart, the EMA will average the last 21 hours of price movement. Popular periods include 21, 50, 100 and 200. When using a moving average in cryptocurrency trading, you can select the length of the average which dictates the amount of periods that will be averaged. They are often used in conjunction with other mathematical indicators and perform best in a trending market. Simple Moving Average (SMA) or Exponential Moving Average (EMA) are two popular, but different, moving average indicators. Moving averages smooth out recent price action to help the trader identify trends, asses trend strength and find support and resistance levels.Ī moving average is calculated by adding the closing prices from a specified number of trading periods and dividing the sum by the number of trading periods.
