Technical Analysis Basic Education Simple vs. Exponential Moving Averages: What's the Difference? Partner Links. Chande Momentum Oscillator Definition, Calculation and Example The Chande momentum oscillator is a technical momentum indicator that calculates relative strength or weakness over a user-defined time frame. Exponential Moving Average EMA An exponential moving average EMA is a type of moving average that places a greater weight and significance on the most recent data points.
Market Breadth Definition Market breadth is a technical analysis technique that gauges the strength or weakness of moves in a major index. Fibonacci Extensions Definition Fibonacci extensions are a method of technical analysis commonly used to aid in placing profit targets.
Adjusting the time frame can remedy this problem temporarily, although at some point, these issues are likely to occur regardless of the time frame chosen for the moving average s. 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 respond quicker to price changes than an average with a longer look back period days. Moving average crossovers are a popular strategy for both entries and exits.
MAs can also highlight areas of potential support or resistance. While this may appear predictive, moving averages are always based on historical data and simply show the average price over a certain time period. Investing using moving average, or any technique requires an investment account with a stockbroker. Investopedia's list of the best online brokers is a great place to start your research on the broker that fits your needs the most.

Muscle contractions may cause bone fractures from either the con-tractions themselves or from falls. A severe shock can cause much more damage to the body than is visible. A person may suffer internal bleeding and destruction of tissues,nerves, and muscles. Sometimes the hidden injuries caused by electrical shock result in a delayed death. Shock is often only the beginning of a chain of events. Even if the electrical current is too small to cause injury, your reaction to the shock may cause you to fall, resulting in bruises, broken bones, or even death.
The length of time of the shock greatly affects the amount of injury. If the shock is short in duration, it may only be painful. A longer shock lasting a few seconds could be fatal if the level of current is high enough to cause the heart to go into ventricular fibrillation. This is not much current when you realize that a small power drill uses 30 times as much current as what will kill. At relatively high currents, death is certain if the shock is long enough. However, if the shock is short and the heart has not been damaged, a normal heartbeat may resume if contact with the electrical current is eliminated.
This type of recovery is rare. The amount of current passing through the body also affects the severity of an electrical shock. Greater voltages produce greater currents.
So, there is greater danger from higher voltages. Resistance hinders current. The lower the resistance or impedance in AC circuits , the greater the current will be. Dry skin may have a resistance of , ohms or more. Wet skin may have a resistance of only 1, ohms. Wet working conditions or bro-ken skin will drastically reduce resistance. The low resistance of wet skin allows current to pass into the body more easily and give a greater shock.
When more force is applied to the contact point or when the contact area is larger, the resistance is lower, causing stronger shocks. Power drills use 30 times as much current as what will kill.
The path of the electrical current through the body affects the severity of the shock. Currents through the heart or nervous system are most dangerous.
