Recap
The trading session saw 201 closed trades, resulting in a win rate of 62.2% and a positive expectancy of +0.77% per trade. The profit factor of 1.70 suggests that winning trades significantly outweighed the losses. Notable successes included 엔켐 (348370) posting a gain of +12.01%, alongside strong performances from 에스원 (012750) at +11.73% and 삼성SDI (006400) at +9.72%. Conversely, the losses were notable, with 와이씨 (232140) recording a -10.16% decline, and 실리콘투 (257720) at -9.21%. Despite the notable drawdowns on some names, the overall positive expectancy indicates a solid day for the executed trades 
.
Lessons from Drawdowns
The losses observed, particularly the -10.16% on 와이씨 (232140) and the -9.21% on 실리콘투 (257720), highlight the sensitivity of certain names to momentum shifts. It is clear that even when the overall market structure appears supportive, individual stock price action can deviate sharply from expectations. The fact that 에스원 (012750) appeared in both a notable win (+11.73%) and a notable loss (-8.05%) suggests that the stock exhibited high volatility within the observed trading window, demanding careful observation of intraday support/resistance levels 
.
Observations
The positive average win size (+3.02%) relative to the average loss size (-2.93%) contributes positively to the overall expectancy. This suggests that when the directional bias is correctly identified, the magnitude of the return can be substantial. The breadth of the results, spanning from a +12.01% peak to a -10.16% trough, underscores the wide dispersion of outcomes across the analyzed securities
