Bar graphs can be used to track multiple currency pairs, different time frames, and various trading strategies. They are an easy way to compare currencies, track market movements and make predictions. They are also used to identify support and resistance levels, and to determine when to enter and exit the market. Bar graphs can help traders make better decisions and maximize profits.
