HTX Sentiment Analyst

Layer 2 analytical skill that reads market mood from 3 dimensions: market-wide fear/greed, smart-money positioning, and breadth (gainers vs losers). Calls one free external API (alternative.me) and composes 2 HTX Layer 1 skills.

When to use this skill

• "What's the market sentiment right now?"
• "Are we in greed territory?"
• "Is BTC positioning crowded?"
• "Is the crowd net long or net short?"
• "Should I be contrarian here?"
• "Sentiment vs price divergence?"

For pure derivatives crowdedness on a specific contract, prefer htx-derivatives-analyst. For pure technicals, prefer htx-technical-analysis.

Underlying tools

Source	What it provides	Cost
https://api.alternative.me/fng/ (external)	Crypto Fear & Greed Index (0-100) — daily, free, no key	free
https://github.com/htx-exchange/htx-skills-hub/elite-positioning	top-trader account + position L/S ratio	free
https://github.com/htx-exchange/htx-skills-hub/spot-market	24h gainers/losers via tickers endpoint	free

If those Layer 1 skills aren't installed:

htx-cli skill install elite-positioning
htx-cli skill install spot-market

Standard workflow

Step 1 — Fetch Fear & Greed (external)

curl -s 'https://api.alternative.me/fng/?limit=30' | jq .

Returns a 30-day history of values 0–100 with labels:

Range	Label
0-24	Extreme Fear
25-44	Fear
45-55	Neutral
56-74	Greed
75-100	Extreme Greed

Step 2 — Pull HTX elite positioning (BTC as proxy for the major-coin crowd, plus user-specified symbol)

htx-cli futures call GET /linear-swap-api/v1/swap_elite_account_ratio \
  -p contract_code=BTC-USDT -p period=4hour --json

htx-cli futures call GET /linear-swap-api/v1/swap_elite_position_ratio \
  -p contract_code=BTC-USDT -p period=4hour --json

Step 3 — Pull breadth from spot tickers

htx-cli spot market tickers --json

Compute client-side:

• count of pairs with change > +5% (strong gainers)
• count with change < -5% (strong losers)
• gainer_to_loser_ratio
• top 5 gainers, top 5 losers

Composite sentiment score

Blend three dimensions to a 0-100 score (higher = greedier / more bullish crowd):

Dimension	Weight	Source
Fear & Greed Index	50%	external API (use it directly, 0-100 already)
Elite positioning	30%	account ratio: 1.0 → 50; 1.5 → 70; 2.0 → 85; <1.0 inverted
Breadth	20%	gainer_to_loser_ratio: 1.0 → 50; 2.0 → 70; 0.5 → 30

Weighted average → label using same Fear/Greed buckets.

Crowdedness interpretation

Cross-reference sentiment with price for divergence signals:

Sentiment	Price (7d)	Read
Extreme Greed	flat / declining	Distribution — crowd long but price not following → reversal risk
Extreme Fear	flat / rising	Accumulation — price holding despite fear → bottom signal
Greed	rising	Trend continuation — bullish, but watch for exhaustion above 80
Fear	falling	Capitulation — bearish but watch for shakeout below 20

What this skill explicitly does NOT do

• ⚠️ No social media sentiment (Twitter/X, Reddit, Weibo, Douyin) — HTX has no native endpoint and we're not paying for LunarCrush yet.
• ⚠️ No KOL monitoring — same reason.
• ⚠️ No on-chain whale flow — needs external paid source (Whale Alert / Nansen).

These gaps are flagged in the output risk_warning so users know what's not modeled.
