The document discusses the appropriate use of indicators for risk management and calculating risk-reward ratios in trading. It notes that indicators should be used objectively to develop trading strategies, rather than creating signals on their own. Traders need to understand their own psychology and risk tolerance before selecting indicators to develop strategies. Both subjective and objective indicators are discussed, as well as how different indicators can provide congruent or incongruent signals. The relationship between indicators and risk management strategies is also covered.
