1) Traders should think in terms of probabilities rather than certainties when making predictions about market movements, as no one can know with absolute certainty how markets will react.
2) Analyzing patterns in market history can provide insights into the probabilities of how markets may react to current conditions.
3) Successful trading systems are those that increase the probabilities in the trader's favor over numerous trades, not those that correctly predict each individual trade. Risk management is crucial for long-term success.
