Recap
The day’s closed activity involved 108 trades, resulting in a win rate of 45.4%. The average outcome suggests a negative expectancy of -0.68% per trade, with a profit factor of 0.61. The average winning trade yielded a gain of +2.31%, while the average losing trade registered a loss of -3.15%. Notable positive outcomes included 성광벤드 (+5.78%), 에이피알 (+4.90%), and 다우데이타 (+4.67%). Conversely, the most significant drawdowns were observed in 원익IPS (-7.08%), 브이엠 (-5.96%), and 고려아연 (-4.74%). 
Observations on Drawdowns
The losses recorded, particularly those exceeding 5% in magnitude, suggest that the market structure presented significant resistance or sudden reversals during the trading window. The spread between the best recorded gain (+5.78%) and the worst loss (-7.08%) indicates a substantial range of volatility was encountered. The negative expectancy, despite several solid wins, suggests that the magnitude of the losses is currently outweighing the gains realized. 
For Next Time
The performance highlights that the risk management aspect, particularly concerning the magnitude of drawdowns, requires continued focus. The trades that resulted in the largest losses suggest that exposure to specific sectors or names during periods of high volatility requires careful calibration. The current data set indicates that the average loss size is substantially larger than the average gain size, which is a key pattern to monitor.
