.
Lessons from Drawdowns
The trades that resulted in the largest losses, such as F&F and SOOP, highlighted instances where momentum reversal occurred more rapidly than anticipated. These outcomes suggest that while identifying strong directional moves is valuable, the market’s ability to quickly negate established trends remains a significant factor to monitor. The magnitude of the losses relative to the average win size underscores the importance of managing the risk profile across multiple positions 
.
Observation
The positive expectancy derived from the day’s closed positions indicates that the selection process captured several profitable market movements. The disparity between the best gain (+26.27%) and the worst loss (-13.32%) suggests a range of market conditions were encountered, confirming the inherent volatility within the KOSPI structure.
