What is important to know is that too many indicators can confuse the trader. That is why we often recommend using maximum two Technical Indicators from each category. Furthermore we recommend that the trader does not choose two Technical indicators that pretty much show the same, such as Relative Strength Index (RSI) and Stochastic.
Think of trading as a Top Down Approach. The trader should use Lagging Indicators to identify the right market conditions to trade. After that the trader should use Leading Indicators to try to get into the trade as fast as possible giving the trader the highest Risk-Reward scenario. Lastly the trader should use Confirming Indicators to see that the move is confirmed. If not then the move might end abruptly.
