Started with ₩100,000 on 2026-11-06 and adding ₩100,000 (≈$75) every month. A Raspberry Pi bot trades a real Korean brokerage account on its own — every number below is real and updated daily. (USD values are approximate, converted at today's rate.)
| 💰 Account value | ₩101,030 (≈$76) |
| 🏦 Total deposited | ₩99,570 (≈$75) |
| 📈 Profit / loss | +₩1,460 (≈$1) (+1.47% of deposits) |
| ⚙️ Bot strategy return (deposits excluded) | +1.47% |
| 📊 Just holding the S&P 500 ETF, same period | +1.63% |
| 🆚 Same deposits, just holding the S&P 500 ETF | ₩101,191 (≈$76) |
| 🧭 Market regime | 🟢 BULL — S&P 500 above its 200-day average → 100% S&P 500 ETF |
| 💱 USD/KRW used above | 1,334.68 (market close 2026-11-13, updated 2026-11-13 16:00 KST) |
| ETF | Shares | Price | Value | Weight |
|---|---|---|---|---|
| 379800 · KODEX 미국S&P500 (S&P 500 ETF) | 4 | ₩22,780 | ₩91,120 | 90.2% |
| Cash | ₩9,910 | 9.8% |
How it works
- Rule: if the S&P 500 (SPY) closes above its 200-day moving average, hold 100% in a Korea-listed S&P 500 ETF (379800 KODEX 미국S&P500). Below it, move half into a short-term interest-rate ETF (357870 TIGER CD금리투자KIS(합성)).
- The account is in Korean won, so the S&P 500 ETF also reflects the USD/KRW exchange rate.
- Only whole shares are bought, so a small account keeps some cash.
- ₩100,000 is deposited every month and invested automatically the next trading day.
- The comparison line shows what the same deposits would be worth if they had simply bought and held the S&P 500 ETF — i.e. whether the 200-day rule actually helps.

The same bot runs two bigger strategies on Korea Investment & Securities' paper-trading server (virtual money) to prove them out before any real money goes in. Rebalanced monthly, and half moves to short-term bonds whenever the index falls below its 200-day average.
