Why these rules? (click to expand)
| Rule | Reads | Why it is in the score |
|---|---|---|
| Trend (SMA20/50) | uptrend vs downtrend stack | Averages strip daily noise; a clean short-over-long stack signals sustained demand - trade with the prevailing direction. |
| RSI(14) | ≤30 oversold / ≥70 overbought | Markets overshoot; extremes historically precede bounces/pullbacks, adding a mean-reversion counterweight. |
| Momentum (20d) | return sign | Documented empirical momentum: recent winners keep winning over months - aligns the verdict with what the chart visibly did. |
| Drawdown (52w high) | >10% below high | Big drawdowns usually mean something fundamental changed; tempers the other rules so we do not buy falling knives. |
| Volume confirm | ≥1.25× 20-bar avg + move direction | Volume is participation: a move on real volume means money acted; on sleepy volume it often fades. Asks "does the crowd agree?" |
Score ≥+2 BUY, ≤−2 SELL, else HOLD. Thresholds are textbook defaults - educational only, not investment advice.
