Trade Log

4/29: Samsung Electronics sold +₩11,004, NAVER sold +₩20,000, SK Telecom new buy, KB Financial additional buy. 4/30: KB Financial sold +₩9,654, LG Electronics new buy. Total 7 trades (3 sells / 4 buys). Zero stop-losses this week.

Trailing Stop Performance

Samsung Electronics, NAVER, KB Financial — all three exits were positive. Samsung fired on a gap-down open, so the gain was small, but there was no loss. All three fell within the intended trailing range (3–6%).

Buy Scans and RS Filter Activity

6 scans during the week (10:00 ×2, 13:00 ×2, 14:00 ×2). On the morning of 4/30, available buying power was only ₩70,000–₩80,000 — not enough for any entry. After KB Financial was sold at 13:50, cash recovered and LG Electronics was entered at the 14:00 scan.

On 4/30, the KOSPI ETF RS baseline rose sharply, pushing Samsung Electronics out of the RS filter. A real-world demonstration that the filter dynamically adjusts candidates as market strength changes.

The 20% cash reserve target logic structurally blocked any chasing buys on the 4/30 morning scans.

Issues Found

P1: Web export ‘result’ key error — reoccurred on 4/30 after a previous fix. Needs full root-cause investigation.
P2: SK Hynix ranks #1 by RS but its share price (~₩1,300,000) repeatedly exceeds the per-trade budget. Universe composition needs review.
P2: Shinhan Financial repeatedly blocked at MA20 deviation of 1.7–1.9%. Parameter adjustment under consideration.
P3: Holiday detection logic for 5/1 not confirmed.

Next Week Checklist

Fully resolve web export bug / confirm holiday detection logic / monitor SK Telecom 12-share position stop-loss level (₩92,521) / decide handling for high-priced stocks / prepare commission and tax accounting (scheduled after 2 weeks of live data).
