Introduction to Trading Forex

2009-12-01T00:31:00.000-08:00

This short introduction explains the basics of trading Forex online, a brief explanation of the markets and the major benefits of trading Forex online. There are also two scenarios describing the implications of trading in a bear as well as a bull market to better acquaint you with some of the risks and opportunities of the largest and most liquid market in the world.
As an additional aid for those who are new to Forex, there is also a glossary at the bottom of this text which explains some of the terms used in connection with currency trading.
Overview Foreign exchange, Forex or just FX are all terms used to describe the trading of the world's many currencies. The Forex market is the largest market in the world, with trades amounting to more than USD 3 trillion every day. Most Forex trading is speculative, with only a low percentage of market activity representing governments' and companies' fundamental currency conversion needs.
Unlike trading on the stock market, the Forex market is not conducted by a central exchange, but on the “interbank” market, which is thought of as an OTC (over the counter) market. Trading takes place directly between the two counterparts necessary to make a trade, whether over the telephone or on electronic networks all over the world. The main centres for trading are Sydney, Tokyo, London, Frankfurt and New York. This worldwide distribution of trading centres means that the Forex market is a 24-hour market.

Gold & forex trading can be a deadly combo!

2009-11-27T09:46:00.000-08:00

MUMBAI (Commodity Online): Combining forex trading with gold trading can be highly lucrative. If you have been following gold prices, you must know that gold prices have reached their historical peak this week.Gold prices recently broke the historical barrier of $1,000 per ounce and now hovering over $ 1,150 per ounce. And, the market is anticipating a dollar depreciation.Whenever, the markets become jittery, investors start buying gold as a hedge against the dollar. Last year, after the stock market crash, many investors started investing in gold as a safe haven against the turmoil in the financial markets. Gold and dollar have an inverse correlation relationship. Gold and dollar are almost near perfect mirror image of each other. US dollar depreciation during the global financial uncertainty has been the primary reason for the gold appreciation as it is viewed as the ultimate form of money. Gold is also seen as the primary safe haven commodity. Countries like China, Russia and India are converting there dollar reserves into gold. This is putting upward pressure on the gold prices. Gold market has been in fact in a secular bull market for the last many years. Now the good news, if you are a forex trader or if you have just started trading forex, then you should know this fact that you can also trade gold along with forex. The technical analysis basics for both markets are almost the same.The details may vary but if you can trade forex, you can also trade gold. As said before, dollar and the gold prices have an inverse relationship so combining forex trading with gold trading can be a perfect hedge. Both compliment each other. Most of the brokers allow gold trading from the same platform that you use to trade forex. If you want to take part in this latest gold rush, you can start trading gold along with forex.

How Your Heart Works

2009-11-14T04:23:00.000-08:00

Everyone knows that the heart is a vital organ. We cannot live without our heart. However, when you get right down to it, the heart is just a pump. A complex and important one, yes, but still just a pump. As with all other pumps it can become clogged, break down and need repair. This is why it is critical that we know how the heart works. With a little knowledge about your heart and what is good or bad for it, you can significantly reduce your risk for heart disease.
Heart disease is the leading cause of death in the United States. Almost 2,000 Americans die of heart disease each day. That is one death every 44 seconds. The good news is that the death rate from heart disease has been steadily decreasing. Unfortunately, heart disease still causes sudden death and many people die before even reaching the hospital.

Certainly no other bodily organ elicits this kind of response. When was the last time you had a heavy pancreas?
In this article, we will look at this important organ so that you can understand exactly what makes your heart tick.

Snow

2009-11-12T08:25:00.000-08:00

Snow is a type of precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds. Since snow is composed of small ice particles, it is a granular material. It has an open and therefore soft structure, unless packed by external pressure. Snowflakes come in a variety of sizes and shapes. Types which fall in the form of a ball due to melting and refreezing, rather than a flake, are known as graupel, with ice pellets and snow grains as examples of graupel. Snowfall amount, and its related liquid equivalent precipitation amount, are determined using a variety of different rain gauges.
The process of precipitating snow is called snowfall. Snowfall tends to form within regions of upward motion of air around a type of low-pressure system known as an extratropical cyclone. Snow can fall poleward of their associated warm fronts and within their comma head precipitation patterns, which is called such due to its comma-like shape of the cloud and precipitation pattern around the poleward and west sides of extratropical cyclones. Where relatively warm water bodies are present, for example due to water evaporation from lakes, lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones. Lake-effect snowfall can be locally heavy. Thundersnow is possible within a cyclone's comma head and within lake effect precipitation bands. In mountainous areas, heavy snow is possible where upslope flow is maximized within windward sides of the terrain at elevation, if the atmosphere is cold enough.

Once on the ground, snow can be categorized as powdery when fluffy, granular when it begins the cycle of melting and refreezing, and eventually ice once it packs down, after multiple melting and refreezing cycles, into a dense mass called snow pack. When powdery, snow moves with the wind from the location where it originally landed, forming deposits called snowdrifts which may have a depth of several meters. After attaching to hillsides, blown snow can evolve into a snow slab, which is an avalanche hazard on steep slopes. The existence of a snowpack keeps temperatures colder than they would be otherwise, as the whiteness of the snow reflects most sunlight, and the absorbed heat goes into melting the snow rather than increasing its temperature. The water equivalent of snowfall is measured to monitor how much liquid is available to flood rivers from meltwater which will occur during the upcoming spring. Snow cover can protect crops from extreme cold. If snowfall stays on the ground for a series of years uninterrupted, the snowpack develops into a mass of ice called glacier. Fresh snow absorbs sound, lowering ambient noise over a landscape due to the trapped air between snowflakes acting to minimize vibration. These acoustic qualities quickly minimize, and reverse once a layer of freezing rain falls on top of snow cover. Walking across snowfall produces a squeaking sound at low temperatures. For motion pictures, the sound of people walking across snow are duplicated through the use cornstarch, salt, and cat litter.
The term snow storm can describe a heavy snowfall while a blizzard involves snow and wind, obscuring visibility. Snow shower is a term for an intermittent snowfall, while flurry is used for very light, brief snowfalls. Snow can fall more than a meter at a time during a single storm in flat areas, and meters at a time in rugged terrain, such as mountains. When snow falls in significant quantities, travel by foot, car, airplane and other means becomes highly restricted, but other methods of mobility become possible: the use of snowmobiles, snowshoes and skis. When heavy snow occurs early in the fall, significant damage occurs to trees still in leaf. Areas with significant snow each year can store the winter snow within an ice house, which can be used to cool structures during the following summer.

What is air made of?

2009-11-12T08:17:00.000-08:00

Dry air is primarily made up of nitrogen (78.09%) and oxygen (20.95%). The remaining 1% is made up of argon (0.93%), carbon dioxide (0.03%) and other trace gases (0.003%). Water vapor (water in its gaseous state) is also present in air in varying amounts.
Interesting facts:
CARBON DIOXIDE: The amount of carbon dioxide, although small, will double in the next 100 years as more petroleum and coal is burned to fuel societies need for energy. About half of the carbon dioxide produced in this way get absorbed by vegetation, which uses it for "food". OXYGEN: While we know that vegetation produces oxygen as part of photosynthesis, the origin of the huge amount of oxygen in the atmosphere is somewhat of a mystery. It is thought to have been produced from chemical reactions in ocean sediments

AH-1 Cobra Background

The AH-1 Cobra was the world's first dedicated (that is, specifically designed) armed attack helicopter. The need for an armed gunship to protect unarmed helicopters had quickly become apparent during the early months of the Vietnam conflict, when many helicopters were lost to ground fire. The AH-1, being fast, heavily armed, and highly maneuverable, proved itself a powerful combatant throughout the rest of the war. Its precedent-setting design has led to many other variations (including some with two engines) and a number of other armed helicopters have been developed by different manufacturers.

The Secret Life of an Anaconda

2009-11-11T04:18:00.000-08:00

Anacondas in the wild spend most of their time hanging out in rivers hunting for their food. They are solitary creatures that are somewhat shy and not many of them are easily seen. They are very well camouflaged in the swamps and bogs in which they thrive. There are some historical reports of early European explorers of the South American jungles seeing giant anacondas up to 100 feet long and some of the native peoples of the South American jungle have reported seeing anacondas up to 50 feet long. No one has caught and measured an anaconda anywhere near that size. It is important to note that when a dead anaconda's hide or skin is laid out it can be stretched very easily, expanding to much longer lengths than the snake exhibited when alive. Reports of outsize anacondas that cannot be verified are usually due to distortions in perception, or a snake skin being disproportionately stretched and inaccurately measured. People are generally really bad at estimating length, especially for larger snakes. In fact, the larger the snake, the larger the margin of error.
Anacondas like to hang out in rivers so it would be difficult to estimate the length of one seen swimming, without seeing the entire snake. It's the anaconda's ability to remain partly hidden in the water that makes it difficult to accurately find (and document) a specimen that exceeds the current world's record.

Ancient Egypt

2009-11-11T03:20:00.000-08:00

Ancient Egypt was an ancient civilization of eastern North Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. The civilization coalesced around 3150 BC[1] with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next three millennia.[2] Its history occurred in a series of stable Kingdoms, separated by periods of relative instability known as Intermediate Periods. Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. Egypt was conquered by a succession of foreign powers in this late period, and the rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province.[3]
The success of ancient Egyptian civilization stemmed partly from its ability to adapt to the conditions of the Nile River Valley. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which fueled social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system, the organization of collective construction and agricultural projects, trade with surrounding regions, and a military intended to defeat foreign enemies and assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes, religious leaders, and administrators under the control of a pharaoh who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs.[4][5]
The many achievements of the ancient Egyptians include the quarrying, surveying and construction techniques that facilitated the building of monumental pyramids, temples, and obelisks; a system of mathematics, a practical and effective system of medicine, irrigation systems and agricultural production techniques, the first known ships,[6] Egyptian faience and glass technology, new forms of literature, and the earliest known peace treaty.[7] Egypt left a lasting legacy. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world. Its monumental ruins have inspired the imaginations of travellers and writers for centuries. A newfound respect for antiquities and excavations in the early modern period led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy, for Egypt and the world.
