Taking full responsibility for trading outcomes is the cornerstone of developing a winning attitude.

This shifts focus from blaming external factors to controlling internal response.

Acting on your own planned ideas forces you to accept responsibility for outcomes, making it harder to rationalize losses.

Random trades allow blame-shifting to external sources.

Calculate the maximum intraday retracement that can occur without violating the symmetry and integrity of the longer-term trend direction.
