Some traders may prefer to use only one or two indicators to simplify their analysis and reduce the risk of conflicting signals. Others may use multiple indicators to gain a more comprehensive view of the market, confirm signals, and filter out false signals.
It's important to note that the number of indicators used is not as important as the quality and reliability of the indicators. Traders should focus on using indicators that are well-suited for their trading strategy, have a proven track record, and provide reliable signals. Additionally, traders should always use indicators in conjunction with other forms of analysis, such as price action and fundamental analysis, to make informed trading decisions.
