Forex Technical Analysis Indicators are usually used to forecast price changes on the currency market. They are calculations which take the volume and price of a certain financial instrument into account. By using Forex indicators, traders can make decisions about market entry and exit. In the MetaTrader 4 trading platform there is a function which allows indicators to be added right into trading graphs or to place them in a special window. Psychological Forex Indicators help to identify market participant sentiment and, based on this, attempt to define possible price movements. The oscillators are used to ascertain the force of the trend or the time when a change in the tendency is to take place.
