⚠️ Correction (2026-07-16): A simulation data defect affecting 2026-07-08 through 07-15 was found, and this journal has been corrected and republished. A signal-persistence failure caused entries to be recorded at stale signal prices instead of live market prices, producing simulated trades at prices and returns that could not have existed in the market. The defective trades have been quarantined from the ledger and the engine has been repaired. This republished version reflects verified, valid trades only.

Recap
The recent set of closed trades showed a mixed performance profile. Out of the seventeen trades closed, the win rate settled at 29.4%. The average profit per winning trade was positive at +2.41%, which was notably higher than the average loss of -0.91% per losing trade, resulting in a positive expectancy of +0.06% per trade. The best single outcome recorded was a gain of +6.16% on 에스앤디 (260970), while the largest drawdown was -3.67% on 농심 (004370). It is pleasant to see the notable gains on 에스앤디 (260970) and 미원에스씨 (268280)

Lessons from Outcomes
The trades that resulted in losses, such as those on 농심 (004370) and 에스티팜 (237690), highlighted the importance of managing the magnitude of drawdowns. The losses, while smaller than the best gains, represented clear instances where the initial thesis was challenged by immediate market action. These outcomes suggest that while capturing significant upside is rewarding, the discipline required to limit losses when the initial momentum fades is equally crucial for maintaining a positive overall expectancy 
.
Observations
The overall profit factor of 1.10 indicates that the gains slightly outweighed the losses across this sample of trades. The positive average win versus average loss ratio suggests that when trades do succeed, they tend to capture meaningful moves. This pattern is something to observe when assessing the relative strength of directional conviction versus the frequency of successful entries
