Social Media Intelligence

This skill integrates financial-intelligence collection methods and quantitative applications across Twitter/X, Telegram, Discord, and Reddit. Inspired by himself65/finance-skills modules such as discord-reader, telegram-reader, and twitter-reader.

1. Overview of the Four Major Financial Social Platforms

1.1 Twitter/X — The FinTwit Ecosystem

Core roles

Core FinTwit circles

• $TICKER cashtag system directly maps discussion to the asset
• Earnings-season sentiment patterns before and after reports
• Real-time reaction speed to policy / macro events, often 15-60 minutes ahead of traditional media

1.2 Telegram — The Core Venue for Crypto Intelligence

Channel types

1.3 Discord — Quant Communities and Project Ecosystems

Important community types

• Quant / DeFi research communities such as Degen Spartan and Messari Research
• Official crypto project Discords with governance discussion and development progress
• Trader communities focused on options flow and on-chain analysis
• NFT / GameFi projects with floor-price alerts and activity monitoring

Distinctive value of Discord

• Community activity directly reflects project health
• Developer channels such as #dev and #build show implementation activity
• Governance participation indicates the willingness of token holders to stay involved

1.4 Reddit — A Barometer of Retail Sentiment

Core subreddits

2. Data Collection Methods

Suggested collection frequency

• r/wallstreetbets around the market open: every 30 minutes
• r/investing / r/stocks: every 4 hours
• r/cryptocurrency: hourly

2.5 Compliance and Privacy Notes

Must comply with

• Twitter API terms: do not resell data to third parties; obey rate limits such as the basic-tier 500,000 tweets/month allowance
• Telegram personal messages must not be collected; only public channels / groups are in scope
• Discord must be accessed through the official Bot API; self-bots violate ToS and may get banned
• Reddit PRAW rate limit: 60 requests/minute for authenticated users

Data storage rules

• Store user IDs in masked form such as hashes; do not retain raw usernames
• Store raw text locally only and do not expose it through public APIs
• Periodically purge raw data older than 30 days and keep only aggregated metrics

3. Sentiment Quantification Methodology

3.1 Text Sentiment Scoring

Option A: VADER (Lightweight, English, Good for Short Social Posts)

# pip install vaderSentiment
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer

def vader_score(text: str) -> dict:
    """Score the sentiment of social-media text using VADER.

    Args:
        text: Raw social-media text such as a tweet, post, or message

    Returns:
        {'pos': float, 'neg': float, 'neu': float, 'compound': float}
        compound is in [-1, 1], where > 0.05 is positive and < -0.05 is negative
    """
    analyzer = SentimentIntensityAnalyzer()
    return analyzer.polarity_scores(text)

Characteristics: No GPU required, suitable for high-frequency batch processing; weaker on finance-specific slang such as "bull" or "moon".

Option B: FinBERT (Finance-Specific BERT)

# pip install transformers torch
from transformers import pipeline

_finbert = None

def get_finbert():
    """Lazily load the FinBERT model. First call takes roughly 1-2 seconds."""
    global _finbert
    if _finbert is None:
        _finbert = pipeline(
            "text-classification",
            model="ProsusAI/finbert",
            tokenizer="ProsusAI/finbert",
        )
    return _finbert

def finbert_score(text: str) -> dict:
    """Classify sentiment in finance text using FinBERT.

    Args:
        text: Finance-related text, truncated to 512 tokens

    Returns:
        {'label': 'positive'|'negative'|'neutral', 'score': float}
    """
    result = get_finbert()(text[:512])[0]
    score_map = {"positive": 1.0, "neutral": 0.0, "negative": -1.0}
    return {
        "label": result["label"],
        "score": score_map[result["label"]] * result["score"],
    }

Characteristics: Stronger understanding of finance terms such as earnings, guidance, beat/miss; GPU acceleration is preferred for large batches.

Option C: LLM-Based (Highest Precision, Best for Long and Complex Text)

def llm_sentiment(text: str, ticker: str | None = None) -> dict:
    """Use an LLM to analyze sentiment in complex finance text.

    Args:
        text: Raw text such as a report summary or Discord thread
        ticker: Related asset symbol, if available

        {'score': float[-1,1], 'label': str, 'reason': str}

    prompt = f"""{context}Analyze the sentiment of the following finance text and return JSON:

7. Caveats and Limitations

1. Limited lead value: Social sentiment usually has IC around 0.03-0.06 on broad indices. It works best as a supporting factor, not a primary one.
2. Manipulation risk: Telegram and Discord signal channels in crypto contain many paid signal groups and pump rings. Source-quality scoring is mandatory.
3. Language bias: VADER and FinBERT are mainly built for English. Chinese social platforms such as Xueqiu or Guba need separate model adaptation.
4. API cost control: Twitter API v2 basic tier allows 500,000 tweets/month, and upgrading from $100 to $5000/month changes economics significantly. Budget collection volume explicitly.
5. Latency vs quality trade-off: Real-time collection is noisier, while daily aggregation gives cleaner signals. Choose based on the strategy horizon.
6. Factor decay: Social-sentiment factor effectiveness decays as more market participants exploit the same signal. Re-test IC regularly.
