This depends on how liquid the currency is, or how much of it is being bought and sold at any one time. The most liquid currency pairs are the ones with the most supply and demand in the Forex market, and this supply and demand is generated by banks, businesses, importers and exporters, and traders. Major currency pairs tend to be the most liquid, with the EUR/USD currency pair moving by 90-120 pips on an average day.
Trading charts simply chronicle the price movements of different trading instruments over time, which allows traders to identify patterns in price movements and make trading decisions based on the assumption that these patterns will repeat in the future. For example, one trading chart format is the Japanese candlestick chart, which is formatted to emphasise high and low price points for certain time increments (these increments can be set by the trader in their trading platform).
Another important point for day trading is to choose a good Forex broker. The main attribute here is the spread and the commissions you have to pay. As a rule, a day trader executes a few transactions every day, and the cheaper this is for you, the more benefits you can get from day trading. Before choosing a brokerage firm, research their offers and track all of the possible expenses associated with day trading.
Inflation levels and trends: Typically a currency will lose value if there is a high level of inflation in the country or if inflation levels are perceived to be rising. This is because inflation erodes purchasing power, thus demand, for that particular currency. However, a currency may sometimes strengthen when inflation rises because of expectations that the central bank will raise short-term interest rates to combat rising inflation.
Set realistic trading goals: It's important to be realistic with your trading expectations, as this will help you assess the best times to open and close trades. Many new Forex traders have very high expectations about their potential profits, and this causes them to trade very aggressively, with large sums of money and fast decisions. Again, start small to test your knowledge and skills, and as you start to reliably achieve the results you want, you can set bigger goals.
