The basics of economics are an area of knowledge that you absolutely need to be familiar with in order to understand price fluctuations. Prices move, or oscillate, based upon their supply and demand. An increase in demand while supply stays constant will lead to an increase in price. In other words, the more people want a scarce item, the more expensive that scarce item will become. If demand stays the same, but the supply increases, the scarce item becomes abundant and prices will drop.
This has a huge bearing on the price of an asset. For example, if you are interested in buying the Japanese yen, you will not pay very many dollars per yen since the market has such a huge amount of yen within it. But if you were to buy the Euro, because there are fewer Euros out in the marketplace, you will end up paying more per Euro than you will yen.
This has nothing to do with demand, however. Each individual currency has its own ebbs and flows when it comes to how badly it is wanted by Trade Vantage. Most currencies will see oscillation over the course of the day as people grow more and less confident in the price that it is moving. This isn’t unique to just currencies, but will apply to all assets up for regular trading. As prices rise, consumers become less and less confident that they will continue to rise. Eventually, it reaches a point where consumers are extremely convinced that they will stop rising and the price actually starts to drop as consumer demand dries up. This doesn’t mean there is no demand—it only means that there is not enough demand to increase the price.
Prices, when looked at with a chart, will be seen to go up and down like a roughly drawn sine curve. This might seem odd at first, but this oscillation takes place at any time period you choose to look at. Whether you are looking at weekly candlesticks or 1 minute, the price will be moving up and down on a seemingly predictable tide of change.
