1) Support and Resistance
• Trendlines are a relatively simple tool that can be used to gauge the overall direction of a given asset, but, more importantly, they can also be used by traders to help predict areas of support and resistance.
• Trendlines are used to identify the levels on a chart beyond which the price of an asset will have a difficult time moving.
• This information can be very useful to traders looking for strategic entry levels or can even be used to effectively manage risk, by identifying areas to place stop-loss orders.
