Moving averages are moving average


Are more technical tools used by technical analysts, financial and strategic as well ..The reason it is a tool that gives the typical value of a data set, whether daily, weekly or other.Ie, it performed that purify and filter these data from the sharp fluctuations that accompany cyclical and seasonal earnings results and conditions to give the public areas and trends in the real movement.Piece and you can specify the path or direction or region where prices move according to the period of these dataThey are markers of a price and later with him .. that is, they are subordinateI mean>>> is the average of the data filter, which helps to clarify the vision.To find out areas of negative and positive areas of the MeanWe must know the signs of entry and exit by the movement of these averages.

Areas in or what is known as the golden cross "golden cross"Is the area to penetrate the line price for the average kineticOr the penetration of the average of the average long-shortThat is, trading above the average kineticThat is, we in the areas of strength and confidence, and the rush to the top.

Areas out or what is known as cross killer "dead cross"Broken line is the area average price of motorAverage short break or for the average long-That is, trading under the average kineticWe are in any areas of weakness accompanied by a lack of trust.

Also was a period when the higher average short-aliasing and increased the intersections with the positive and negative, which result in decisions to enter and exit the wrong cause considerable damage and confusion more ..Which is called "the wrong signals false signals"

Also abound in the wrong signals if the traffic sideAre advised not to venture bid for signals crossing of great importance in such casesWhich cause great losses.This is known as the movement to "stings prices whipsaws"

In general, the movement of averages with long periods, which contain data longer"Long moving average"Be more confident and stoicism of the averages of the short period data contains a short"Short moving average"

One of the advantages that make this the most important indicator of indicators and gives her at all because it is based on real prices and follow, unlike some of the indicators that contain complex equations involving trading volumes and number of transactions and values ​​and more.Also is the best and most heartfelt follow-up price movement along the lines of direction which is different analysts to pinpointAnd each analyst has a line of abuse and different from another analyst and margins are sometimes large.The average motor contains a calculation standard for all.

The piece, we find that most of the analysts who rely on "expert-mail" in determining entry and exit signalsIs dependent primarily on the intersections of arithmetic averages of kinetic rates or indicators.What distinguishes this type of indicators is adopted on the overall price movement regardless of the volumes and valueWhich leaves no room for emotion in decision-making.

And more deeply as the details of these averages ..We find that her methods of calculation and weights of multipleDifferent analysts to handle and give one of them more confidence from the other.Where we can calculate the average rates of movement: -Or opening or closing the upper or lowerEach analyst has his style in dealing withAlthough the majority deals with the closing prices as it represents the final outcome.

Also to the average kinetic many types ..Each type of method and calculation results and the advantages and disadvantages differ from one another.We will address this issue to the most important of these species and the most common among analysts and try to explain to classify and easy to understand and take advantage of them.

Kinetic types of averages: -


1 - simple average kinetic"Simple moving average" SMA

This is the kind of averages over the spread between the traders and the reason is due to the ease and being the first types of averages and the spread of knowledge.But with the passage of time and developments in the calculations for the adaptation of these averages as commensurate with the ambitions and aspirations of the analyst, the analyst has better options.The disadvantage of this type of averages because it gives all the prices, the same importance and weight within the time series, whether modern or old. Can not afford to rely entirely upon the knowledge of recent changes compared Balkadimp.The method adopted to calculate this average gives each period within the time series calculated according to their value regardless of its time and locationAlso ignores this kind of sharp price averages in the first period after the string to enter into a new period in Ember do not enter any interest in his plans for the future.

And the calculation of this type are ..(The collection of prices for all time periods and divided by the number)The next day, we delete the first day of the time series and add the new day and divide the same number of period and so on ...As is evident from the calculation ignoring the first day of the series after the addition of a new day.

2 - average kinetic likely or weighted"Weighted moving average" WMA

A favorite of senior analysts and experts inches WorldWhere he gives the average for each period according to the relative importance of different location, whether modern or old. And takes into account the importance of modern arrogance of prices. It is what distinguishes this type of averages.For this reason, called this kind of weighted averages or likely because it gives the weights and the weight of different prices depending on location.It gives no weight and the likelihood of the price according to its position in the time series of dataPeriod, the period I 1 II 2 3 ... third period, and so on,,,,Thus, the method of calculating this average as follows: -(Hit the value of each period and location, rounded up, divided them on the number of periods).Thus, we gave each period to its likely importance in the time series.The disadvantage of this type of averages have the disadvantage of the previous year "simple"Where both intermediate ignore the first period and Isagtanha calculation of the string after the entry of entirely new period in the string calculation.

3 - the average kinetic exponential"Exponential moving average" EMA

That the average managed process for exponential calculation and collection of all prices to be included in the string calculation for each specified time period did not ignore any old priceBut introduced within the accounts of the string modern.Which is thought senior analyst of the importance of back and look at him as a stronger and truer, especially for long periods. Where he does not ignore the ancient periods such as the former two types for each period by decreasing the importance of old location.For this average calculation is complex and difficult and very long For this reason it is important to use the computer to complete such complex operations.
