Recap
The day’s closed trading activity showed a mixed performance profile. Out of 449 closed trades, the overall win rate was low at 7.1%. The average expected return across these trades was negative, at -3.14% per trade. Profitability was marginal, indicated by a profit factor of 0.05. The average winning trade yielded a gain of 2.08%, while the average losing trade resulted in a loss of 3.54%. Notable positive outcomes included gains from 셀바스AI (+13.40%) and EMB (+3.80%). Conversely, significant drawdowns were observed, particularly with 야스 (-29.44%) and LG이노텍 (-13.17%), which weighed heavily on the overall performance. 
Analysis of Outcomes
The disparity between the average win size and the average loss size suggests that while some profitable trades were executed, the magnitude of the losses was disproportionately large relative to the gains. The frequency of trades, combined with the negative expectancy, points to a period where capital preservation proved challenging. The notable losses, such as those seen in 야스 and LG이노텍, highlight instances where directional conviction did not translate into risk-adjusted returns. 
For Next Time
The outcomes from the losing trades, particularly those with deep drawdowns, underscore the importance of managing the risk exposure on the downside. The data suggests that the risk taken on the losing legs significantly outweighed the positive contributions from the winning trades. A focus on controlling the maximum loss per trade appears warranted when reviewing the sequence of events.
