Trade or Sit Out? A Data-Driven Market Decision Engine

I made a "should I be trading?" dashboard.

Scores the market across 5 pillars:

- volatility (put/call ratio, vix, positioning)

- trend (spx vs 20d, 50d, 200d ma's)

- breadth (advancing/declining, nas highs/lows)

- momentum (sector leaders, laggards, % participation)

- macro (fomc, rates, geopolitics)

Each is weighted, combined, and averaged to give me a score for the current environment.

Basically a yes, no, or stay small.

Sometimes I just need someone (or something) to remind me to stay out.

Happy to share the prompt if you guys want it...but I made this with perplexity_ai's Computer.

here is the prompt I used on perplexity_ai max (Computer)...feel free to mess around with the weightings, etc.

PROMPT:

Build “Should I Be Trading?” — Bloomberg Terminal-Style Market Dashboard

Build a live, auto-refreshing Bloomberg Terminal-style web dashboard called “Should I Be Trading?” that evaluates the current stock market environment and outputs a clear, actionable trading decision for swing traders.

Core Output

The system must display:

1. Decision: YES / CAUTION / NO

2. Market Quality Score: 0–100%

3. Execution Window Score: 0–100% (separate)

4. Plain-English Summary: concise explanation of the environment

Data Inputs (Live or Latest Available)

Volatility / Risk

- $Cboe Volatility Index(VIX)$ level, trend (5d slope), and 1-year percentile

- $VIX Volatility Index(VVIX)$ (if available)

- Put/Call ratio (estimate if needed from VIX regime)

Trend & Structure

- S&P 500 ( $SPDR S&P 500 ETF Trust(SPY)$ ) vs 20 / 50 / 200-day moving averages

- $Invesco QQQ(QQQ)$ vs 50-day moving average

- SPY 14-day RSI

- Market regime classification: uptrend / downtrend / chop

Breadth

- % of stocks above 20d / 50d / 200d moving averages

- NYSE Advance/Decline line + daily ratio

- Nasdaq new highs vs new lows

- McClellan Oscillator (optional if available)

Momentum / Participation

- All 11 S&P sector ETFs: XLK, XLF, XLE, XLV, XLI, XLY, XLP, XLU, XLB, XLRE, XLC

- Top 3 vs bottom 3 sector performance (relative strength spread)

- % of stocks making higher highs

Macro / Liquidity

- 10-Year Treasury yield (level + short-term trend)

- Dollar Index (DXY trend)

- Fed stance (derived or labeled: hawkish / neutral / dovish)

- FOMC calendar (flag if event within 72 hours or same day)

- Optional: CPI / Jobs flags

Scoring System

Calculate category scores (0–100):

- Volatility: 25%

- Momentum: 25%

- Trend: 20%

- Breadth: 20%

- Macro/Liquidity: 10%

Then compute:

Market Quality Score = weighted average

Decision Logic

- 80–100 → YES

Full position sizing, press risk

- 60–79 → CAUTION

Half size, A+ setups only

- <60 → NO

Avoid trading, preserve capital

Execution Window Score (Critical Layer)

Separate score that evaluates whether setups are actually working:

- Are breakouts holding above pivot levels?

- Are leading stocks maintaining gains after breakout?

- Are pullbacks being bought quickly?

- Is there multi-day follow-through?

Score 0–100 and factor into final explanation (but NOT the main score weighting).
