Traders rely on price charts, volume charts and other mathematical representations of market data (called studies) to find the ideal entry and exit points for a trade. Some studies help identify a trend, while others help determine the strength and sustainability of that trend over time. Technical analysis can add discipline and minimize emotion in your trading plan. It can be hard to screen out fundamental impressions and stick with your entry and exit points as planned. While no system is perfect, technical analysis helps you see your trading plan through more objectively and dispassionately.
