Charting methods are essential for automated trading systems, and some of the most common ones are line charts, bar charts, candlestick charts, and point and figure charts. Line charts show the closing prices of an asset over time and can be used to identify the overall direction and strength of a trend, as well as support and resistance levels. Bar charts provide more detail, displaying the opening, closing, high, and low prices of an asset for each time period. They can be used to identify price patterns such as reversals, breakouts, and continuations. Candlestick charts are similar to bar charts but use different colors and shapes to represent the price movements of an asset. They can be used to identify doji, hammer, engulfing, and shooting star patterns as well as sentiment and psychology. Point and figure charts only show significant price changes of an asset while ignoring time and minor fluctuations. They help eliminate noise and focus on main trends and signals while also projecting price targets and objectives.
