Yes, study every indicator that you happen to come across in your trading and use it even for a shorter while ... that will not only broaden your understanding about the market's requirements and you will also be aware of what to expect in certain circumstances. For instance, take Bollinger Bands for example ... if bands were invented to determine volatility range of the market that must tell you a lot about market behavior and help you understand what a chart pattern delves into when in big picture.
