MA60 Filter — First Real-Money Validation

What I was more interested in was the MA60 filter. NAVER, Kia, and Hyundai Motor — three downtrend stocks — were correctly blocked from entry.

The API replacement made on 4/21 after market close (switching to inquire-daily-itemchartprice) was validated in live trading for the first time. 65 data points returned; MA20 + MA60 calculated correctly.

Budget Safety Margin — Partial Validation

Applied safe_budget = available_budget × 0.95:

  • 13:00 scan — first application successful
  • 14:00 scan — failed again (situation exceeded the 5% buffer)

Confirmed today that a 5% margin is insufficient in certain scenarios. Will review improvement options after market close tomorrow.

KT — New Position

Bought KT (030200). Entry confirmed after MA20 > MA60 uptrend check. End-of-day: -0.16%.

End-of-Day Results

  • Closing portfolio value: ₩4,906,290
  • Shinhan Group (-1.28%) is on watch for tomorrow

To Check Tomorrow
