Random article: Basics of Technical Analysis
By technical analysis we should basically understand employment of price chart (and results of its math interpretation) for further market and price forecast. Technical analysis rests upon repeated nature of market and implies that ups and downs of currency quotations on charts are rotated according to certain time periods.
An advantage of technical analysis is its universal application: with its help one can research any financial contract for any period of time. The market accounts for everything. That means that any event, which could affect price behavior is already accounted by market and is reflected on the price chart. This proposition means that all factors impacting the price will be definitely reflected in its behavior, therefore, it is required to monitor quote graph.
