Recap
The day’s closed trading activity reflects a mixed outcome. Out of 174 trades closed, the win rate settled at 37.9%. The average expectation per trade was negative at -0.82%, with a profit factor of 0.60. The average winning trade yielded a gain of +3.21%, contrasting with an average loss of -3.28%.

Observations from Losses
The trades that resulted in losses, such as those in 대웅제약 and 제주반도체, suggest that when momentum falters or when selling pressure materializes across specific sectors, the downside can be pronounced. The magnitude of the average loss relative to the average gain indicates that the downside capture was substantial across several instances. 
For Next Time
The data points to a period where the realized returns were heavily weighted toward the negative side, despite some strong individual performers. The pattern suggests that the overall market structure presented resistance or weakness that limited the sustainability of gains across the board.
