📐 Score formula

Each instrument's daily score (0–1) is a weighted combination of four technical indicators:

• RSI(14): overbought/oversold measure. Weighted at ≤30 and ≥70.
• MACD(12, 26, 9): short/long EMA difference for trend turns.
• EMA(20, 50): price position relative to short/long moving averages.
• Momentum (20d): cumulative 20-day return.

Each indicator is normalized to 0–1 and weight-averaged into the final score.

🏷️ Signal classification

• Score ≥ 0.7: strong
• 0.4 ≤ Score < 0.7: neutral
• Score < 0.4: weak

📖 How to read quant scores (5 steps)

When first reading the score page, follow these 5 steps. Informational, not buy/sell guidance.

1. Check the score range — Start with the total score (0–100). Scores are relative percentile within a sector, not absolute value.
2. Read the V/Q breakdown — Look at Value (V) and Quality (Q) separately. V is the sector percentile of price multiples (PER/PBR etc.), Q is the percentile of profitability and stability metrics (ROE, margin, debt).
3. Compare within sector — Compare scores against other instruments in the same sector. The category label (growth/value/defensive/other) helps frame the profile.
4. See the 30-day trend — On the instrument page, watch the 30-day score sparkline. The direction of change often carries more information than the level itself.
5. Mind the limits — Scores are sector-relative quantitative information, not buy or sell signals. Final decisions remain the user’s responsibility.
