Recap
The session saw a high volume of closed trades, totaling 97 transactions. The overall performance metrics indicate a positive expectancy of +1.76% per trade, supported by a profit factor of 2.86. The average winning trade realized a gain of +4.11%, significantly outperforming the average loss of -2.78%.

.
Lessons from Outcomes
The losses recorded, such as those in 에스티팜 (-5.59%) and 엘앤에프 (-5.13%), suggest that while the overall directional bias was favorable, specific names proved resistant to the prevailing momentum. These instances highlight that even within a generally positive market structure, individual stock-specific headwinds or sudden profit-taking can override broader sector strength 
. The spread between the best gain (+15.39%) and the worst loss (-5.59%) confirms a wide dispersion of outcomes across the sampled names.
For Next Time
The data suggests that the positive expectancy is being generated by a clear separation between successful trades and those that incurred losses. Observing the magnitude of the wins relative to the losses indicates that capturing the upper end of the daily range remains a key feature of the recent trading activity 
. The consistency in the win rate, combined with the positive expectancy, points toward a robust capture of intraday movements when the setup criteria are met.
