Technical analysis is a school of market analysis that studies the internal dynamics of an asset’s price action with a view to forecasting its future movements. Technical analysts presuppose that everything that needs to be known about a given asset has already been priced in, they also take as a given that trends repeat themselves and that market participants behave similarly in similar situations. For these reasons they focus exclusively on applying mathematical tools to historical price action and studying chart patterns in order to determine whether an asset is looking bullish or bearish.
