Let me analyze the K200 market based on the provided data and the rules given.

Given Rules:

Today's Data (2026-05-15):

From market/midday (most recent for today):

K200 is trading at 1195.81, down 3.81% from the previous close, and USD/KRW has risen to 1498.44, a 0.39% increase from yesterday's 1492.68. The S&P500 closed at 7501.24, up 0.77% from the prior close of 7444.25.

Now I'm looking at the market signals that will drive my analysis. The RSI data isn't provided in the dataset, so I'll need to rely on the other indicators. Based on the current market conditions—K200's significant decline, the won strengthening against the dollar, and the S&P's positive movement—I need to weigh each factor carefully to determine the likely direction. USD/KRW: 1498.44 (USD/KRW 상승 → DOWN)

Let me reconsider the rules more carefully. The USD/KRW movement rule says that when the dollar strengthens against the won, that signals DOWN. Looking at the actual data from the timestamps: USDKRW moved from 1492.68 to 1498.44, which is an increase in the rate, meaning the dollar strengthened, so that's a DOWN signal. For S&P500, the price went from 7444.25 to 7501.24, which is clearly an increase and signals UP. I'm cross-checking the K200 price across different timestamps to make sure I'm reading the most recent midday data correctly—the 1195.81 figure represents today's trading so far. For the S&P500, I only have yesterday's close at 7501.24 since today's data hasn't come in yet, which is an uptick from the previous close. For K200's direction, the midday price of 1195.81 is sharply lower than yesterday's close of 1243.17, but without an explicit RSI value I can't directly apply the oversold rule. However, the active signals—particularly the critical FUTURES_BASIS signal with a perfect weight of 1.00—might give me directional context even if RSI isn't available. I'm calculating the weighted directional signals by multiplying each indicator's weight by its directional value (UP as +1, DOWN as -1). The results show critical-level signals like FUTURES_BASIS and KOSPI_FOREIGN_NET both pointing strongly downward, with high-priority signals like FOREIGN_NET_5D and KS200_MA5 also indicating DOWN, while lower-priority indicators like SP500 and NASDAQ are mixed or trending UP.

The overall weighted sum comes to -6.11, which clearly points to a DOWN direction. But the user is asking me to apply a specific decision framework that counts UP and DOWN signals rather than using weighted averaging—counting how many signals are UP versus DOWN and determining direction from that count, with ties defaulting to the previous day's direction. I'm realizing the discrepancy—the active signals list includes some factors I didn't explicitly account for, like the critical FUTURES_BASIS reading and others with high/medium weights that are clearly pointing downward. The weighted calculation approach makes more sense here than the simple count method, since it's capturing the actual momentum shift more accurately. Since I'm only given market data without RSI values, I'll stick with the three main signals I can extract: the S&P 500 rise points to UP, the USD/KRW rise points to DOWN, and the significant K200 drop indicates DOWN. That gives me 2 DOWN signals against 1 UP, so the direction should be DOWN based on the signal count. Looking at the midday data more carefully, the K200 dropped sharply from yesterday's close, and given how oversold it is with a critical FUTURES_BASIS signal, I'm leaning toward DOWN, though I'm second-guessing whether that sharp decline actually indicates further downside or potential mean reversion. I'll stick with my analysis and recommend DOWN based on the clear signals: the K200's sharp drop, the USD/KRW weakness, and foreign outflows all pointing lower, even though the S&P500's positive movement suggests some resilience. Now I'm building the JSON response.

Signal Analysis:

Based on rules:

Down signals: 2 (환율, K200 crash)

Up signals: 1 (S&P)

Since we have 2 DOWN vs 1 UP, direction is DOWN.

Let me format as JSON:
