RSI or Relative Strength Index

RSI or Relative Strength Index is an oscillator and is constructed by measuring a stock or index' gains against their losses. So if the range of its gains is greater than its losses the oscillator would rise, conversely if the range of its losses were greater the oscillator would fall. Like Moving Averages the oscillator needs a time period offset to measure this activity. The normal default number used by many technicians is 14 although I have also seen and used 20.

The oscillator just like a stock moves up and down in value. The oscillator only has a range of 1 -100 and it is within the confines of this range that it attempts to define what an overbought or oversold condition is in a stock or market. Most programs or analysts follow it using the default below 30 as oversold and above 70 as overbought. This range of under 30 to over 70 does not mean that a stock will not continue to sell down or continue to move up once it hits these ranges. The oscillator can remain below 30 or above 70 for weeks or months depending on which chart you are looking at. There are some who watch for the RSI to pass 50 as an indication that price is trending more dynamically in one direction or the other.

There are many times when the oscillator will not reach 30 during a correction and not reach 70 during an uptrend. We use this indicator as a way of gauging the relative strength of price now to price previous. Those investors that use charts to gauge the significance of price activity want to know if price is strengthening or weakening. It is in this manner that we can help visually to determine if a stock is trending up significantly or downwards in a fashion that will allow us to trade it profitably. Charts are a must if you are an investor/speculator. Without charts and indicators one has no way of knowing whether a stock or market is building strength or becoming weaker.

The RSI can be used in conjunction with other indicators to time the market and gain a, more, well rounded view of trading activity.

The RSI oscillator is also subject to interpretation when viewed through a different, figurative, lens filter. Since the oscillator is subject to movement up and down that activity can be measured or gauged against other activity that has taken place prior to it. Perhaps the most well known (subjective/objective) measure of this activity is called divergence.

Divergence occurs when an oscillator either rises more than or less than it did previously at a same or similar price. This occurrence can also be measured when the oscillator is significantly higher or lower at a current high or low price than at a previous high or low price. Highs and highs and lows and lows can be measured against one another this way. There are other significant nuances to divergence we will not go into in this article but suffice it to say, for now, it can be very important in gauging relative market strength or weakness. Divergence is frequently used to time the market to determine if an uptrend is beginning to fade or if a sell off has lost steam and is getting ready to reverse. Divergence should also be used in conjunction with other tools to more accurately time when this becomes of greater importance.

Trendlines can help to time this activity, with greater precision. As the oscillator begins to rise, or fall,. we watch for pivot points (please see more on pivot points in our article Trendlines and Pivot Points) that have trendlines intersecting them. These trendlines, inevitably, are crossed by price during a reversal or continuation of trend. It is during this crossing that we must watch the oscillator's activity and gauge whether it is in a strong position or a weak position and is the break of the trendline supporting the direction of the oscillator. If the oscillator and trendline both support the direction and magnitude of the move then we have a greater opportunity to profit from a trade.

This is actually a fairly simple relationship to distinguish but it takes time to appreciate its value which can only be done through observation and patience.

Rolex Datejust

Rolex is the largest single luxury watch brand by far,producing about 2,000 watches per day.Rolex watches are popularly considered status symbols,many people all over the world are proud to own a Rolex watch.Rolex has innovated a series of watch models,Rolex Air king,Rolex Datejust,Rolex Day Date,Rolex Daytona,Rolex Explorer,Rolex GMT,Rolex Milgauss,Rolex Prince,Rolex Sea-Dweller,Rolex Submariner,Rolex Yacht-Master.Now i am going to discuss one of the watch models,Rolex Datejust.

Rolex Datejust was launched in 1945,it was the Jubilee Datejust Model 4467,it was only available in 18K gold at first.This model features a fine coin edged bezel,a gold edged date window,alternating red/black date figures,a tiny bubbleback winder and a deeply domed back.

1954:dramatic change

In 1954,Rolex introduced the Cyclops lens at Basel,this allowed the date to be read easier and has now become part of the Rolex signature.

1957:the new movement calibre 1065

In 1957,the new movement calibre 1065 was introduced,it was much lighter and much slimmer than its predecessor making the old domed back obsolete.And in 1957,the stainless steel Rolex Datejusts were released.

1962:one of the most popular watch Rolex has ever produced.

The stainless and gold Datejusts were introduced around 1962 and has proved to be one of the most popular Rolex's ever produced.Since there was quite a large gap between sales in gold Datejusts and steel Datejust,Rolex filled the void with a mixed metal model.

1970:"Mid Size" watches

2030 movement was a scaled down version of the 1030 movement and was immediately fitted to a series of watches universally known as the "Mid Size".These watches were perfect 80% replicas of the Oyster Perpetual and Datejust were available in all the metal and dial variations. They have proved to be one of Rolex's success as they were very popular in the Europe, South America and Asia. Because they were an in between size they also appealed to large women or small men to whom the standard sizes did not appeal.

At the end of the 1980's:Sapphire mineral crystal glass

At the end of the 1980's,Rolex Datejust watches were fitted with the sapphire mineral crystal glass,it was more aesthetically pleasing as it slimmed the look of the Datejust and it also rendered the glass virtually scratch proof, which was extremely practical.

Nowadays,people are more likely to choose a top quality Rolex watch with cheap price,so a Rolex Datejust replica watch will be a good choice to many of them who like Rolex Datejust.You must admit,a replica watch  has price advantage when compared with original,though someone still has a doubt about their quality.

What is a fair price for a used camera and lenses?

A friend is offering me a Cannon A-1 35mm camera(about 20 years old)+ several lenses. These include a macro zoom lens and a wide angle lens, as well as a 28-50mm zoom lens and a few others that are just basic lenses. All together about 7 lenses. Also an auto winder attachment, a couple of cable releases, about 12 filters, several lens adapters, a light meter and a bellows. I need to figure out what to offer her, but I don't know what is a fair price. I don't want to cheat either one of us. Does anybody have any idea what would be a fair price to offer for these items. I must have the camera and at least a couple of lenses, along with the cable releases, and at least a couple of filters. So an idea of what to offer for the smaller number of items would also be helpful. Thank you.

Since Canon developed the EOS camera system, the A-1 vintage cameras became obsolete ... sort of. While they are still great cameras and can shoot amazing images. What you will not get is auto-focus and the ability to use the new Canon EOS and DSLR's cameras.

A fair price could be as low as $200 for the whole kit. You will not be cheating anyone by knowing the limitations of the camera and lenses.
