There are many controversies about this issue. However, my opinion is not to use too much indicator in one chart because you’ll get confused. On the other hand, it is good to take a look at more indicators. It is important to find out which of the indicator is working for the given financial instrument. There many combinations that you must consider. One of the best for me is a combination of Elliot waves with Fibo. Another, good strategy is finding top and bottoms by using RSI, MACD, OsMa and etc. However, the signals that this indicator will generate must be confirmed by candle formations, support/resistance and patterns. Trend lines are the best way to catch the move. Also, most indicators give good signals when used at higher time frame charts.
