The Day the First Trailing Stop Profit Came In
Live account day 9. Today the trailing stop produced an actual profit for the first time.
LG Chem hit an intraday high of ₩402,000, then triggered an auto-sell at ₩393,500 — a -2.1% drop from the peak. The position had been opened just the day before and closed out in one session. Return: +2.88%.
At the same time, KB Financial received two additional buy orders in the ₩158,800–₩159,200 range. It hasn’t reached the trailing activation threshold yet, so the position remains open.

Today’s observation
The trailing stop fired in a live trade for the first time. It triggered as designed and the log recorded it correctly. That said, this upgrade lowered the activation threshold from +4% to +3% — how that difference plays out in practice needs more time to observe.
