The RSI study offers signals that are sensitive to trend change, but the study has been and remains steadily bullish since turning up on 6 February 2014.
Financial markets are predictable because segments of price action fit together in a limited number of patterns that are not random. Markets are unpredictable too because there is enough variability in the patterns to hide the trend at some stages of development. I am fascinated by the market and spend a lot of time working to identify price trends so I can exploit them for profit.
