Common Terms in MT4 (2): Overnight Interest (Swap Fee): Overnight interest in foreign exchange refers to the interest generated by a forex trader after holding a particular currency for a full day (overnight). This interest is due to the different interest rates of different currencies, resulting in an interest differential. For example, when you deposit money in a bank, you earn interest, and when you borrow from a bank, you have to pay interest. When trading currency pairs, it usually involves two currencies. For instance, buying EURUSD actually means buying (equivalent to a deposit) EUR and selling (equivalent to a loan) USD. This creates an interest differential, also known as overnight interest. Candlestick Chart: A candlestick chart is a graphical representation of the price movement of an asset. It consists of multiple candlesticks, and each candlestick is based on four data points: the opening price, the highest price, the lowest price, and the closing price. Each candlestick represents a specific time period, which can be 1 minute, 1 hour, 1 day, and so on. This corresponds to different chart types such as the 1-minute chart (M1), 1-hour chart (H1), and 1-day chart (D1). For example, if you plot a candlestick every hour on a chart, you will get a 1-hour candlestick chart, where each candlestick represents one hour and includes the four data points. Similarly, you can create weekly candlestick charts and monthly candlestick charts.
