Often, chart patterns are used in candlestick trading, which makes it slightly easier to see the previous opens and closes of the market. There is no one ‘best’ chart pattern, because they are all used to highlight different trends in a huge variety of markets. Chart patterns are the basis of technical analysis and require a trader to know exactly what they are looking at, as well as what they are looking for. A chart pattern is a shape within a price chart that helps to suggest what prices might do next, based on what they have done in the past.
