Do you think it is healthy to look at MACD and RSI indicator for a single chart and wait for them to agree, or is it just better to follow only either?

It is not necessarily unhealthy to consider both MACD and RSI indicators on a single chart, but it is important to use them in a way that complements your trading strategy and does not lead to redundant or conflicting signals.

1. Complementary Use: Using indicators from different categories, such as momentum (like RSI) and trend (like MACD), can provide a more comprehensive view of the market. The RSI can help identify momentum plays, while the MACD finds trends. This combination can enhance your understanding of price movements and improve timing for trade entries and exits.
2. Avoiding Redundancy: Be cautious of using multiple indicators that provide similar information, as this can lead to information overload and potential confusion. For instance, using multiple momentum indicators like MACD, RSI, and Stochastic can result in redundant signals.
3. Price Action Priority: It is important not to rely solely on indicators but also to consider price action, as it is the most direct relationship with market participants and is less lagging. Price action can provide valuable insights that may not be captured by indicators.
4. Customization: Tailor your approach to your trading style and the specific markets you engage in. For example, if you are a trend follower, you may want to emphasize trend indicators like MACD and de-emphasize momentum indicators like RSI.

In summary, it is beneficial to consider multiple indicators, but only if they complement each other and do not create redundant signals. Price action should always be the primary focus, and indicators should be used to enhance your understanding and confirm your analysis.
