When a moving average is heading upward and the price is above it, the security is in an uptrend. Conversely, a downward sloping moving average with the price below can be used to signal a downtrend Another method of determining momentum is to look at the order of a pair of moving averages. When a short-term average is above a longer-term average, the trend is up. On the other hand, a long-term average above a shorter-term average signals a downward movement in the trend. Moving average trend reversals are formed in two main ways: when the price moves through a moving average and when it moves through moving average crossovers. The signal of a trend reversal is when one moving average crosses through another. For example, as you can see in following figure, if the 10 day moving average crosses bellow the 25-day moving average, it is a negative sign that the price will start to decrease. If the periods used in the calculation are relatively short, for example 10 and 25, this could signal
