From 25067a56f7dfe895667043185905c98dd5c5752d Mon Sep 17 00:00:00 2001 From: Ahmet Guzererler Date: Wed, 18 Mar 2026 07:54:21 +0100 Subject: [PATCH 1/5] feat: add Finnhub integration layer, tests, and evaluation report MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a complete Finnhub data vendor integration as a supplementary source alongside Alpha Vantage — zero changes to existing functionality. New dataflow modules: - finnhub_common.py: exception hierarchy, thread-safe rate limiter (60/min), _make_api_request - finnhub_stock.py: get_stock_candles, get_quote - finnhub_fundamentals.py: get_company_profile, get_financial_statements, get_basic_financials - finnhub_news.py: get_company_news, get_market_news, get_insider_transactions - finnhub_scanner.py: market movers (S&P 500 basket workaround), indices, sectors, topic news - finnhub_indicators.py: SMA, EMA, MACD, RSI, BBANDS, ATR via /indicator endpoint - finnhub.py: facade re-exporting all public functions New tests: - test_finnhub_integration.py: 100 offline (mocked HTTP) tests — all passing - test_finnhub_live_integration.py: 41 live integration tests — skip gracefully when FINNHUB_API_KEY unset Evaluation report (docs/finnhub_evaluation.md): - Full coverage matrix vs Alpha Vantage across 5 data categories - Free tier viability analysis (60 calls/min) - Unique capabilities: earnings calendar, economic calendar, XBRL as-filed filings - Recommendation: add as supplementary vendor for calendar data only Co-Authored-By: Claude Sonnet 4.6 --- docs/finnhub_evaluation.md | 244 +++ tests/test_finnhub_integration.py | 1359 +++++++++++++++++ tests/test_finnhub_live_integration.py | 419 +++++ tradingagents/dataflows/finnhub.py | 80 + tradingagents/dataflows/finnhub_common.py | 245 +++ .../dataflows/finnhub_fundamentals.py | 309 ++++ tradingagents/dataflows/finnhub_indicators.py | 224 +++ tradingagents/dataflows/finnhub_news.py | 245 +++ tradingagents/dataflows/finnhub_scanner.py | 370 +++++ tradingagents/dataflows/finnhub_stock.py | 143 ++ 10 files changed, 3638 insertions(+) create mode 100644 docs/finnhub_evaluation.md create mode 100644 tests/test_finnhub_integration.py create mode 100644 tests/test_finnhub_live_integration.py create mode 100644 tradingagents/dataflows/finnhub.py create mode 100644 tradingagents/dataflows/finnhub_common.py create mode 100644 tradingagents/dataflows/finnhub_fundamentals.py create mode 100644 tradingagents/dataflows/finnhub_indicators.py create mode 100644 tradingagents/dataflows/finnhub_news.py create mode 100644 tradingagents/dataflows/finnhub_scanner.py create mode 100644 tradingagents/dataflows/finnhub_stock.py diff --git a/docs/finnhub_evaluation.md b/docs/finnhub_evaluation.md new file mode 100644 index 00000000..bc371a61 --- /dev/null +++ b/docs/finnhub_evaluation.md @@ -0,0 +1,244 @@ +# Finnhub API Evaluation Report +## Fitness for TradingAgents Multi-Agent LLM Framework + +**Date**: 2026-03-18 +**Branch**: `feat/finnhub-evaluation` +**Status**: Evaluation only — no existing functionality modified + +--- + +## Executive Summary + +Finnhub is **not a drop-in replacement** for Alpha Vantage. It fills two genuine gaps AV cannot cover (earnings calendar, economic calendar) and offers higher-fidelity as-filed XBRL financial statements. For the rest of our use cases, AV + yfinance already covers the ground adequately. + +**Recommendation**: Add Finnhub as a **supplementary vendor** for calendar data only. Keep AV for news sentiment and movers; keep yfinance as primary. + +--- + +## 1. API Overview + +| Feature | Finnhub Free Tier | +|---------|------------------| +| Rate limit | 60 calls/min | +| Daily limit | None (rate-limited only) | +| Data delay | 15-min delayed on free; real-time on paid | +| Python SDK | `finnhub-python` (pip install) — NOT used here (raw requests only) | +| Base URL | `https://finnhub.io/api/v1/` | +| Auth | `?token=` query param | + +--- + +## 2. Coverage Matrix vs Alpha Vantage + +### Category 1: Core Stock Data + +| Feature | Alpha Vantage | Finnhub | Winner | +|---------|--------------|---------|--------| +| Daily OHLCV | `TIME_SERIES_DAILY_ADJUSTED` | `/stock/candle?resolution=D` | Tie | +| Split-adjusted close (bundled) | ✅ Always bundled | ❌ Free tier not adjusted | **AV** | +| Split history | Via adjusted_close | `/stock/splits` (separate call) | AV | +| Response format | Date-keyed JSON | Parallel arrays (`t[]`, `o[]`, ...) | AV (more ergonomic) | + +**Gap**: Finnhub free-tier candles are NOT split-adjusted. Adjusted close requires a separate `/stock/splits` + `/stock/dividend` call and manual back-computation. + +--- + +### Category 2: Technical Indicators + +| Indicator | Alpha Vantage | Finnhub | +|-----------|--------------|---------| +| SMA | `/SMA` endpoint | ❌ Not provided | +| EMA | `/EMA` endpoint | ❌ Not provided | +| MACD | `/MACD` endpoint | ❌ Not provided | +| RSI | `/RSI` endpoint | ❌ Not provided | +| BBANDS | `/BBANDS` endpoint | ❌ Not provided | +| ATR | `/ATR` endpoint | ❌ Not provided | + +**Critical Gap**: Finnhub has a `/indicator` endpoint but it maps to the same indicator names — this was implemented in our integration layer to use it. The endpoint works but is **not documented prominently** in Finnhub's free tier docs and may have availability issues. Our `finnhub_indicators.py` module implements it with full fallback. + +**Alternative**: Use `pandas-ta` (pure Python) to compute indicators from raw candle data — this is vendor-agnostic and actually more reliable. + +--- + +### Category 3: Fundamentals + +| Feature | Alpha Vantage | Finnhub | +|---------|--------------|---------| +| Company overview | `OVERVIEW` (40 fields, 1 call) | `/stock/profile2` + `/stock/metric` (2 calls) | +| Balance sheet | `BALANCE_SHEET` | `/financials?statement=bs` OR `/financials-reported` (XBRL) | +| Income statement | `INCOME_STATEMENT` | `/financials?statement=ic` | +| Cash flow | `CASH_FLOW` | `/financials?statement=cf` | +| As-filed XBRL data | ❌ Normalized only | ✅ `/financials-reported` | +| Earnings surprises | ❌ | ✅ `/stock/earnings` — beat/miss per quarter | +| Earnings quality score | ❌ | ✅ `/stock/earnings-quality-score` (paid) | +| Analyst target price | In `OVERVIEW` | In `/stock/metric` | + +**Finnhub Advantage**: `/financials-reported` returns actual XBRL-tagged SEC filings — highest fidelity for compliance-grade fundamental analysis. AV only provides normalized/standardized statements. + +**Finnhub Gap**: Requires 2 API calls to replicate what AV's `OVERVIEW` returns in 1. + +--- + +### Category 4: News & Sentiment + +| Feature | Alpha Vantage | Finnhub | +|---------|--------------|---------| +| Ticker news | `NEWS_SENTIMENT?tickers=X` | `/company-news?symbol=X&from=Y&to=Z` | +| Per-article NLP sentiment score | ✅ `ticker_sentiment_score` + `relevance_score` | ❌ Free tier: aggregate buzz only | +| Macro topic news | `economy_macro`, `economy_monetary` | ❌ Only: general, forex, crypto, merger | +| Aggregate sentiment | — | `/news-sentiment` (buzz metrics) | +| Social sentiment (Reddit/X) | ❌ | `/stock/social-sentiment` (paid) | +| Insider transactions | `INSIDER_TRANSACTIONS` | `/stock/insider-transactions` | +| Insider sentiment (MSPR) | ❌ | `/stock/insider-sentiment` (free) | + +**Critical Gap**: AV's per-article `ticker_sentiment_score` with `relevance_score` weighting is a genuine differentiator. Our `news_analyst.py` and `social_media_analyst.py` agents consume these scores directly. Finnhub free tier provides only aggregate buzz metrics, not per-article scores. **Replacing AV news would degrade agent output quality.** + +**Finnhub Advantage**: Insider sentiment aggregate (`MSPR` — monthly share purchase ratio) is not available in AV. + +--- + +### Category 5: Market Scanner Data + +| Feature | Alpha Vantage | Finnhub | +|---------|--------------|---------| +| Top gainers/losers | ✅ `TOP_GAINERS_LOSERS` | ❌ No equivalent on free tier | +| Real-time quote | `GLOBAL_QUOTE` | `/quote` (cleaner, more fields) | +| Market status | ❌ | ✅ `/market-status?exchange=US` | +| Stock screener | ❌ | `/stock/screener` (paid) | +| **Earnings calendar** | ❌ | ✅ `/calendar/earnings` — **unique, high value** | +| **Economic calendar** | ❌ | ✅ `/calendar/economic` (FOMC, CPI, NFP) — **unique, high value** | +| IPO calendar | ❌ | ✅ `/calendar/ipo` | +| Index constituents | ❌ | ✅ `/index/constituents` (S&P 500, NASDAQ 100) | +| Sector ETF performance | Via SPDR ETF proxies | Same SPDR ETF proxy approach | + +**Critical Gap**: Finnhub has no `TOP_GAINERS_LOSERS` equivalent on the free tier. Our `finnhub_scanner.py` workaround fetches quotes for 50 large-cap S&P 500 stocks and sorts — this is a functional approximation but misses small/mid-cap movers. + +**Finnhub Unique**: Earnings and economic calendars are zero-cost additions that directly enhance our geopolitical_scanner and macro_synthesis agents. + +--- + +## 3. Unique Finnhub Capabilities (Not in Alpha Vantage) + +These are additive value — things AV cannot provide at any tier: + +| Capability | Endpoint | Value for TradingAgents | +|-----------|----------|------------------------| +| **Earnings Calendar** | `/calendar/earnings` | Event-driven triggers; pre-position before earnings volatility | +| **Economic Calendar** | `/calendar/economic` | FOMC, CPI, NFP dates for macro scanner context | +| **As-Filed XBRL Financials** | `/financials-reported` | Highest fidelity fundamental data for deep-think agents | +| **Earnings Surprise History** | `/stock/earnings` | Beat/miss rate — strong predictor signal for LLM reasoning | +| **Insider Sentiment (MSPR)** | `/stock/insider-sentiment` | Aggregated monthly buying pressure score | +| **Index Constituents** | `/index/constituents` | Know S&P 500 / NASDAQ 100 members without hardcoding | +| **Market Status** | `/market-status` | Gate scanner runs to market hours | +| **Options Chain** | `/stock/option-chain` (paid) | Put/call ratios, implied vol — not in AV at any tier | +| **Social Sentiment** | `/stock/social-sentiment` (paid) | Reddit/X structured signal | +| **Supply Chain Graph** | `/stock/supply-chain` (paid) | Peer/supplier/customer relationships | +| **Congressional Trading** | `/stock/usa-spending` | Insider signal from public officials | + +--- + +## 4. Data Quality Assessment + +| Dimension | Alpha Vantage | Finnhub | Notes | +|-----------|--------------|---------|-------| +| Real-time quotes | Delayed, occasionally stale | Delayed free / real-time paid; cleaner | Finnhub slightly better | +| Adjusted historical data | Known issues with reverse splits | More accurate back-adjustment | Finnhub better | +| Fundamental accuracy | Normalized, some restated-data lag | As-filed XBRL option is gold standard | Finnhub better for high-fidelity | +| News sentiment quality | ✅ Per-article NLP scores (genuine differentiator) | Aggregate only (free tier) | **AV wins** | +| API reliability | Generally stable; rate limits documented | Generally stable; free tier mostly reliable | Tie | + +--- + +## 5. Free Tier Viability + +### Scanner call budget analysis + +| Scanner Stage | AV Calls | Finnhub Equivalent | Notes | +|--------------|----------|-------------------|-------| +| Market movers (1 endpoint) | 1 | 50 `/quote` calls | Workaround — massively more expensive | +| Per-mover fundamentals (5 tickers) | 5 `OVERVIEW` | 10 (profile2 + metric × 5) | 2× call count | +| News (3 topics) | 3 | 2 `/news` categories | Reduced topic coverage | +| Sector ETFs (11) | 11 | 11 `/quote` | 1:1 | +| **Total per scan** | ~30 | ~73 | Over free tier per-minute budget | + +**Verdict**: Finnhub as a **full replacement** exceeds the 60 calls/min free tier budget for a complete scan. As a **supplementary vendor** for calendar data only (2-3 calls per scan), it fits comfortably. + +--- + +## 6.

Integration Architecture (Proposed for Future PR) + +If we proceed with adding Finnhub as a supplementary vendor, the changes to existing code would be minimal: + +```python +# default_config.py — add Finnhub to calendar-specific routes +"vendor_calendar_data": "finnhub", # earnings + economic calendars (new category) +"vendor_filings_data": "finnhub", # as-filed XBRL (optional deep mode) +``` + +```python +# interface.py — extend fallback error types +except (AlphaVantageError, FinnhubError, ConnectionError, TimeoutError): +``` + +```python +# .env.example — add new key +FINNHUB_API_KEY=your_finnhub_api_key_here +``` + +New tools to add in a follow-up PR: +- `get_upcoming_earnings(from_date, to_date)` → `/calendar/earnings` +- `get_economic_calendar(from_date, to_date)` → `/calendar/economic` + +--- + +## 8. Recommendation Summary + +| Category | Decision | Rationale | +|----------|----------|-----------| +| Daily OHLCV | Keep yfinance primary | Free, no split-adjust issue, already working | +| Technical Indicators | Compute locally (`pandas-ta`) | Neither AV nor Finnhub is reliable; local is better | +| Fundamentals (quick) | Keep AV `OVERVIEW` | 1 call vs 2; sufficient for screening | +| Fundamentals (deep) | Add Finnhub `/financials-reported` | XBRL as-filed for debate rounds / deep-think agents | +| News sentiment | Keep AV | Per-article NLP scores are irreplaceable for agents | +| Market movers | Keep AV `TOP_GAINERS_LOSERS` | No viable Finnhub free alternative | +| **Earnings calendar** | **Add Finnhub** | Not available in AV — high signal, low cost (1 call) | +| **Economic calendar** | **Add Finnhub** | Not available in AV — critical macro context | +| Insider transactions | Either AV or Finnhub | Finnhub has additional `insider-sentiment` MSPR | + +**Bottom line**: Add Finnhub's free calendar endpoints as a zero-cost enhancement to the macro scanner. Everything else stays as-is. The integration layer built in this PR is ready to use — it just needs the routing wired in `interface.py` and the calendar tool functions added to `scanner_tools.py`. + +--- + +## 9.
