tradingagents/CHANGELOG.md

Changelog

All notable changes to TradingAgents are documented here.

The format is based on Keep a Changelog, and this project follows Semantic Versioning. Breaking changes within the 0.x line are called out explicitly.

[Unreleased]

Fixed

• SEC EDGAR cash flow statements find capital expenditure for filers that moved it to purchases of productive assets (NVIDIA since fiscal 2022, Amazon since 2016), whose recent periods read as empty.

[0.5.0] — 2026-09-18

Point-in-time integrity across every dated path, decisions that are recorded as they were made, backtesting over a grid of tickers and dates, the caller's portfolio as run input, and SEC EDGAR fundamentals served as filed.

Highlights

• Fundamentals as filed. SEC EDGAR serves US company statements as they stood on the run's date: a period that has ended but has not been filed is not served, and a figure restated later still reads as first reported. Keyless, opt-in via the vendor chain.
• Backtesting. run_backtest runs the pipeline over a ticker and date grid into its own decision log, and summarize scores the settled cells; tradingagents backtest does the same from the CLI.
• Portfolio context. propagate(..., portfolio=...) and --portfolio let the trader, risk and portfolio agents size against real holdings. A run without one is never treated as a flat book.
• Decisions are recorded as made. An unreadable decision is flagged for review everywhere instead of becoming a tradeable Hold, and a rating argued against is no longer read as the call.

Point-in-time and honest attribution

• Dated tools take the run's date from graph state, so an omitted or later date cannot reach a vendor. (#1331, #1319, #1118)
• Insider filings and prediction-market odds are bounded by the run date; insider rows state that a trade becomes public when its Form 4 is filed.
• A feed that never observed a window reports it as unavailable rather than as an absence, across news, Reddit and StockTwits.
• The resolved company identity says when it describes today rather than the run date.
• The verification snapshot quotes the prices the vendor reported, never a gap-filled value.
• A vendor failure is a vendor failure: yfinance raises instead of returning its errors as text, an outage is not reported as a company with no data, and a chain where every vendor is unavailable says so instead of ending the run.
• The macro vintage pin is clamped to the vendor's own clock, so a run dated today cannot ask for a vintage it does not have.
• A historical run is not served a present-day company profile by either fundamentals vendor. (#1300)

Decisions and evaluation

• The labelled rating decides, whatever separates it, and prose naming several ratings is reviewed rather than guessed.
• Decision prompts state the shape of their answer, so a provider without structured output still returns a readable decision.
• A report that was not produced says so, instead of appearing as an empty section.
• Backtest scoring reads the direction each rating claimed: a Sell that fell is a hit, and Hold reports no hit rate.
• The outcome window is configurable (holding_period_days), and reflection states the window it judges.
• A settled decision is not logged twice, and a failed reflection no longer stops the next run. (#645)
• The trader states entry and stop levels as prices, so a percentage no longer fails the whole proposal. (#1288)

CLI

• tradingagents backtest, with --run-id to continue an interrupted sweep. (#1234)
• The previous run's selections come back as prompt defaults. (#1236, #920)
• A run with no readable rating says so; the live view no longer scrolls; messages that read like Python values are shown. (#649, #784)
• The state log keeps non-ASCII readable. (#1081)

Data sources

• SEC EDGAR fundamentals vendor (US filers, keyless).
• Hong Kong and Shanghai tickers resolve to the symbols Yahoo serves. (#1342, #957, #1260)
• Reddit is fetched as one combined request per run. (#1286)
• One OHLCV cache file per symbol. (#1330)

Models

• Current lineups for every provider: GPT-6 Astra and the GPT-5.6 family, Gemini 3.8 Flash, Claude Opus 5 and Fable 5.1, Grok 4.6, DeepSeek Flash, Qwen 3.8, GLM-5.3, MiniMax M3, Kimi K3 and the current Mistral snapshots.
• Every provider accepts a model ID the picker does not list.
• GLM traffic goes to the platform its key belongs to, and Ollama structured output no longer sends a tool_choice it rejects. (#1062)

Changed

• The memory log records REVIEW for a decision with no readable rating, where it previously recorded Hold.
• Optional fields the model did not provide are named as such rather than omitted.
• Removed dependencies nothing imports: backtrader, redis, setuptools, langchain-experimental, parsel, tqdm. (#1353, #1070)

[0.4.0] — 2026-08-31

Look-ahead and point-in-time fixes across the data and memory layers, clearer decision signals, working CLI checkpoint resume, and the GPT-5.6 / GLM-5.3 models.

Fixed

• FRED macro look-ahead. Historical macro requests were served from today's data vintage, leaking later revisions into a backtest; both the observations and metadata requests now pin the vintage to the as-of date. (#1275)
• Social sentiment look-ahead. StockTwits and Reddit were fetched with no date, so a historical run showed today's chatter as if it were from the as-of date; the social path is now trimmed to the analysis window, via one shared UTC half-open window rule (dataflows/date_window) used by news too. (#1220)
• Memory point-in-time guard. get_past_context returned every resolved lesson regardless of the run date; each resolved entry now records the date its outcome became known, and a historical run only sees lessons resolved by the trade date. (#1251)
• Premature reflection. A decision was settled on a partial return if a rerun happened before its holding window fully traded; resolution now waits for the full window. (#1169)
• Latest OHLCV bar dropped. The newest bar with a NaN close was silently dropped before the date cutoff, making the previous trading day look like the latest; dates are normalized per element (DST- and non-US-market safe) and a missing latest close raises rather than falling back. (#1201)
• Debate opening fabrication. The first speaker in each debate round rebutted an empty opponent response, fabricating the other side; all five debators now open with their own case when no opponent has spoken. (#1176)
• Silent Hold. An unparseable Portfolio Manager rating (including a fullwidth colon) was coerced to a tradeable Hold; it now surfaces a REVIEW sentinel, with parse_rating keeping its silent default for compatibility callers. (#1170)
• --checkpoint was a no-op on the CLI. Checkpoint setup lived only in propagate(); the CLI streamed the checkpointer-less graph. The lifecycle is now shared, and a resume feeds None so LangGraph continues the interrupted run instead of duplicating messages. (#1249)
• DeepSeek via OpenRouter. deepseek/<id> fell through to default capabilities and had object-form tool_choice forced on it; the official namespace is stripped so it reuses the native DeepSeek quirks. (#1199)
• Trader price grounding. The Trader saw only the digested plan; it now also receives the technical market report so entry/stop levels anchor to real price structure. (#1167)

Added

• Configurable output-token cap. max_tokens / TRADINGAGENTS_MAX_TOKENS, forwarded to every provider (Gemini as max_output_tokens), so a model that emits unbounded reasoning can be bounded instead of hanging. (#1204)
• Latest models. Added the GPT-5.6 family (gpt-5.6 / gpt-5.6-terra / gpt-5.6-luna) and GLM-5.3 (glm-5.3, glm-5.3-flash). The default models are now gpt-5.6 (deep) and gpt-5.6-luna (quick).

[0.3.1] — 2026-07-05

Correctness and stability patch: data look-ahead, graph-router crash-safety, checkpoint identity, crypto sentiment sources, and configurable resilience.

Fixed

• Alpha Vantage look-ahead filter now runs. The fundamentals payload is a JSON string, so the dict-only guard skipped filtering and future-dated reports leaked into historical runs; parse before filtering. (#1115, @zachthebird)
• News analyst prompt matches the tool. The prompt advertised get_news(query, ...) but the tool takes a ticker; aligned to stop hallucinated free-text query calls. (#1116, @shcheuk)
• Shared debate/risk routers can't crash mid-run. Both routers return more targets than any one edge mapped; every edge now shares the complete path map, so a fall-through under prompt/i18n/refactor drift stays routable. (#1088, @Fr3ya, @sa7an7, @Sushanth012)
• Checkpoint resume respects graph shape. The thread id folds in selected analysts, debate/risk depth, and asset mode, so a resume under different choices no longer continues the wrong graph. (#1089, @bossjoker1, @Ghraven)
• Crypto sentiment sources resolve. StockTwits lists crypto as <BASE>.X (Yahoo's BTC-USD 404s) and Reddit needs the base symbol to match; the social path now maps crypto correctly for both. (#1113, @suremadoreai)

Added

• Configurable LLM retry budget. llm_max_retries / TRADINGAGENTS_LLM_MAX_RETRIES is forwarded to every provider, so a transient 429 burst no longer aborts a run. (#1091, @yanggaome)
• Bedrock API-key auth. AWS_BEARER_TOKEN_BEDROCK authenticates Amazon Bedrock without AWS access keys and takes precedence over an ambient AWS_PROFILE. (#1103, @praxstack)
• Latest Claude models. Added Claude Sonnet 5 (claude-sonnet-5) and Fable 5 (claude-fable-5); effort control now covers the Claude 5 line.

[0.3.0] — 2026-06-22

Stabilization and extensibility release: a CI gate, a unified verified data-access contract, a provider and data-vendor registry, and a maintenance sweep that hardened config precedence, the model catalog, data resilience, and structured output.

Added

• CI gate. GitHub Actions runs the pytest suite across Python 3.10-3.13, strict ruff, and a clean-install smoke that imports the package and CLI to catch undeclared dependencies. (#994, #197)
• Provider registry. OpenAI-compatible providers register as a single spec, and a generic openai_compatible endpoint covers vLLM, LM Studio, and relays. Adds NVIDIA NIM, Kimi, Groq, Mistral, and a native Amazon Bedrock client.
• Macro and prediction-market vendors. FRED macro indicators and Polymarket event probabilities, surfaced to the news and macro analysts.
• Programmatic report output. TradingAgentsGraph.save_reports() writes the same report tree the CLI produces, for headless and API runs. (#1037)
• Env-configurable reasoning depth via TRADINGAGENTS_OPENAI_REASONING_EFFORT, TRADINGAGENTS_GOOGLE_THINKING_LEVEL, and TRADINGAGENTS_ANTHROPIC_EFFORT, each gated to the models that accept it.

Changed

• Verified data-access contract. Symbol normalization on every vendor path (identity, returns, CLI, news); the configured vendor list is the exact resolution chain with no silent fallback to unselected vendors; a typed VendorError taxonomy; look-ahead-safe news windows; stale-OHLCV rejection; inclusive yfinance date ranges.
• Config precedence. An explicit TRADINGAGENTS_* value or CLI flag now wins over interactive defaults for debate and risk round counts, --checkpoint / --no-checkpoint, and the Docker provider profile; invalid boolean env values fail loudly. (#975, #976, #977)
• Current-generation model catalog. Refreshed provider lineups; retired gpt-4.1, Claude Sonnet 4.5, and the Gemini 2.5 line.
• Optional vendors degrade instead of aborting a run: a failed macro or prediction-market lookup returns a no-data sentinel.
• Analyst prompts lead with the current date so tool-call date ranges anchor to the run date rather than the model's training cutoff. (#836)

Fixed

• Instrument identity. Deterministic ticker-to-company resolution prevents wrong-company hallucination, and a verified market-data snapshot grounds price and indicator claims. (#814, #830)
• Social and market data sources. Reddit RSS-first with 429 backoff, StockTwits transport hardening, and Alpha Vantage timeout plus key-versus-rate-limit handling.
• Structured output. Local OpenAI-compatible servers no longer reject object-form tool_choice; a thinking model that returns no parsed result falls back to free text; null-ish strings in optional price fields coerce to None. (#1038, #1051, #1057)

Removed

• The no-op analyst_concurrency_limit config knob; parallel analyst execution is planned for a later release. (#979)
• The unused committed uv.lock. (#1030)

[0.2.5] — 2026-05-11

Added

• Grounded Sentiment Analyst. The renamed sentiment_analyst now reads real Yahoo News, StockTwits, and Reddit data before generating its report, replacing the prior flow that could fabricate social posts under prompt pressure. (#557, #607)
• MiniMax provider with the full M2.x catalog (M2.7 / M2.5 / M2.1 / M2 plus highspeed variants, 204K context). Dual-region: Global (MINIMAX_API_KEY) and China (MINIMAX_CN_API_KEY).
• Dual-region Qwen and GLM with separate keys per region — international (DASHSCOPE_API_KEY, ZHIPU_API_KEY) and China (DASHSCOPE_CN_API_KEY, ZHIPU_CN_API_KEY), selectable via a secondary region prompt. (#758)
• TRADINGAGENTS_* env-var configurability for DEFAULT_CONFIG. Override llm_provider, deep/quick model IDs, backend_url, output_language, debate-round counts, checkpoint flag, and benchmark ticker via .env with type-aware coercion (string / int / bool). (#602)
• Interactive API-key detection in the CLI. When the selected provider's key is missing, the CLI prompts for it and persists the value to .env so the analysis run continues without restart.
• Remote Ollama support. OLLAMA_BASE_URL points the CLI and the programmatic client at a remote ollama-serve. The CLI surfaces the resolved endpoint and warns on common malformed inputs. Adds a "Custom model ID" option for models pulled via ollama pull. (#648, #768)
• Configurable news-fetch parameters in DEFAULT_CONFIG — per-ticker article limit, macro headline limit, lookback window, and macro search queries. (#606, #683)
• Configurable alpha benchmark for non-US tickers. Replaces hardcoded SPY with regional indices for .NS (^NSEI), .T (^N225), .HK (^HSI), .L (^FTSE), .TO (^GSPTSE), .AX (^AXJO), .BO (^BSESN); explicit benchmark_ticker override available. Eliminates FX drift dominating alpha for non-USD listings. (#628, #684)
• Multi-language output covers every user-facing agent — researchers, risk debators, research manager, and trader, ending the previous partial-localization reports. (#575)
• Model catalog refresh. OpenAI GPT-5.5 frontier, Anthropic Claude Opus 4.7, Gemini 3.1 Flash-Lite GA, xAI Grok 4.20, Qwen 3.6 line. Versioned IDs only; auto-shifting aliases moved to the "Custom model ID" option.

Changed

• Sentiment Analyst is now consistently named across the CLI dropdown, status panel, and final reports (previously the backend was renamed but the CLI still said "Social Analyst"). The AnalystType.SOCIAL = "social" wire value is kept for saved-config back-compat.

Fixed

• Structured output works on DeepSeek V4 / reasoner and MiniMax M2.x. Those providers reject tool_choice per their tool-calling docs; the binding flow now skips it automatically via a capability table.
• pip install . installations pick up the project .env when running the CLI as a console script. (#747)
• Reports save end-to-end — streamed chunks were previously dropped from complete_report.md. (#719, #736)
• Ticker prompt preserves exchange suffixes (.SH, .SZ, .SS, .HK, .T, etc.) for A-share, HK, Tokyo, and other non-US flows. (#770)
• Docker permission errors no longer block first-run write to ~/.tradingagents/. (#519, #627, #672, #771)
• Config state no longer leaks between runs when sub-dicts are mutated; set_config partial updates preserve sibling defaults. (#788)
• max_recur_limit config actually applies — previously read but not forwarded to the propagator. (#764)
• Missing-API-key error names the exact env var to set. (#680)
• Quieter startup — suppressed the noisy upstream LangChainPendingDeprecationWarning from langgraph-checkpoint; will be removed once that package ships its fix.

Security

• Ticker path-traversal validation at every filesystem-path site (cache, checkpoint database, results) so a malicious ticker cannot escape its intended directory. (#618)

0.2.4 — 2026-04-25

Added

• Structured-output decision agents. Research Manager, Trader, and Portfolio Manager now use llm.with_structured_output(Schema) on their primary call and return typed Pydantic instances. Each provider's native structured-output mode is used (json_schema for OpenAI / xAI, response_schema for Gemini, tool-use for Anthropic, function-calling for OpenAI-compatible providers). Render helpers preserve the existing markdown shape so memory log, CLI display, and saved reports keep working unchanged. (#434)
• LangGraph checkpoint resume — opt-in via --checkpoint. State is saved after each node so crashed or interrupted runs resume from the last successful step. Per-ticker SQLite databases under ~/.tradingagents/cache/checkpoints/. --clear-checkpoints resets them. (#594)
• Persistent decision log replacing the per-agent BM25 memory. Decisions are stored automatically at the end of propagate(); the next same-ticker run resolves prior pending entries with realised return, alpha vs SPY, and a one-paragraph reflection. Override path with TRADINGAGENTS_MEMORY_LOG_PATH. Optional memory_log_max_entries config caps resolved entries; pending entries are never pruned. (#578, #563, #564, #579)
• DeepSeek, Qwen (Alibaba DashScope), GLM (Zhipu), and Azure OpenAI providers, plus dynamic OpenRouter model selection.
• Docker support — multi-stage build with separate dev and runtime images.
• scripts/smoke_structured_output.py — diagnostic that exercises the three structured-output agents against any provider so contributors can verify their setup with one command.
• 5-tier rating scale (Buy / Overweight / Hold / Underweight / Sell) used consistently by Research Manager, Portfolio Manager, signal processor, and the memory log; Trader keeps 3-tier (Buy / Hold / Sell) since transaction direction is naturally ternary.
• Pytest fixtures — lazy LLM client imports plus placeholder API keys so the test suite runs cleanly without credentials. (#588)

Changed

• backend_url default is now None rather than the OpenAI URL. Each provider client falls back to its native default. The previous default leaked the OpenAI URL into non-OpenAI clients (e.g. Gemini), producing malformed request URLs for Python users who switched providers without overriding backend_url. The CLI flow is unaffected.
• All file I/O passes explicit encoding="utf-8" so Windows users no longer hit UnicodeEncodeError with the cp1252 default. (#543, #550, #576)
• Cache and log directories moved to ~/.tradingagents/ to resolve Docker permission issues. (#519)
• SignalProcessor reads the rating from the Portfolio Manager's rendered markdown via a deterministic heuristic — no extra LLM call.
• OpenAI structured-output calls default to method="function_calling" to avoid noisy PydanticSerializationUnexpectedValue warnings emitted by langchain-openai's Responses-API parse path. Same typed result, no warnings.

Fixed

• Empty memory no longer triggers fabricated past-lessons in agent prompts; the memory-log redesign makes this structurally impossible since only the Portfolio Manager consults memory and only when entries exist. (#572)
• Tool-call logging processes every chunk message, not just the last one, and memory score normalization handles empty score arrays. (#534, #531)

Removed

• FinancialSituationMemory (the per-agent BM25 system) and the dead reflect_and_remember() plumbing; subsumed by the persistent decision log.
• Hardcoded Google endpoint that caused 404 when langchain-google-genai changed its API path. (#493, #496)

0.2.3 — 2026-03-29

Added

• Multi-language output for analyst reports and final decisions, with a CLI selector. Internal agent debate stays in English for reasoning quality. (#472)
• GPT-5.4 family models in the default catalog, with deep/quick model split.
• Unified model catalog as a single source of truth for CLI options and provider validation.

Changed

• base_url is forwarded to Google and Anthropic clients so corporate proxies work consistently across providers. (#427)
• Standardised the Google api_key parameter to the unified api_key form.

Fixed

• Backtesting fetchers no longer leak look-ahead data when curr_date is in the middle of a fetched window. (#475)
• Invalid indicator names from the LLM are caught at the tool boundary instead of crashing the run. (#429)
• yfinance news fetchers respect the same exponential-backoff retry as price fetchers. (#445)

0.2.2 — 2026-03-22

Added

• Five-tier rating scale (Buy / Overweight / Hold / Underweight / Sell) introduced for the Portfolio Manager.
• Anthropic effort level support for Claude models.
• OpenAI Responses API path for native OpenAI models.

Changed

• risk_manager renamed to portfolio_manager to match the role description shown in the CLI display.
• Exchange-qualified tickers (e.g. 7203.T, BRK.B) preserved across all agent prompts and tool calls.
• Process-level UTF-8 default attempted for cross-platform consistency (note: this approach did not actually take effect; replaced in v0.2.4 with explicit per-call encoding="utf-8" arguments).

Fixed

• yfinance rate-limit errors are retried with exponential backoff. (#426)
• HTTP client SSL customisation is supported for environments that need custom certificate bundles. (#379)
• Report-section writes handle list-of-string content gracefully.

• @yang1002378395-cmyk — HTTP client SSL customisation (#379)

0.2.1 — 2026-03-15

Security

• Patched langchain-core vulnerability (LangGrinch). (#335)
• Removed chainlit dependency affected by CVE-2026-22218.

Added

• pyproject.toml build-system configuration; the project now installs via modern packaging tooling.

Removed

• setup.py — dependencies consolidated to pyproject.toml.

Fixed

• Risk manager reads the correct fundamental report source. (#341)
• All open() calls receive an explicit UTF-8 encoding (initial pass).
• get_indicators tool handles comma-separated indicator names from the LLM. (#368)
• Propagation initialises every debate-state field so risk debaters never see missing keys.
• Stock data parsing tolerates malformed CSVs and NaN values.
• Conditional debate logic respects the configured round count. (#361)

0.2.0 — 2026-02-04

This is the largest release since the initial public version. The framework moved from single-provider to a multi-provider architecture and grew several production-ready surfaces.

Added

• Multi-provider LLM support (OpenAI, Google, Anthropic, xAI, OpenRouter, Ollama) via a factory pattern, with provider-specific thinking configurations.
• Alpha Vantage integration as a configurable primary data provider, with yfinance as a community-stability fallback.
• Footer statistics in the CLI: real-time tracking of LLM calls, tool calls, and token usage via LangChain callbacks.
• Post-analysis report saving — the framework writes per-section markdown files (analyst reports, debate transcripts, final decision) when a run completes.
• Announcements panel — fetches updates from api.tauric.ai/v1/announcements for the CLI welcome screen.
• Tool fallbacks so a single vendor outage does not stop the pipeline.

Changed

• Risky / Safe risk debaters renamed to Aggressive / Conservative for consistency with the displayed agent labels.
• Default data vendor switched to balance reliability and quota across community deployments.
• Ollama and OpenRouter model lists updated; default endpoints clarified.

Fixed

• Analyst status tracking and message deduplication in the live display.
• Infinite-loop guard in the agent loop; reflection and logging hardened.
• Various data-vendor implementation bugs and tool-signature mismatches.

0.1.1 — 2025-06-07

Removed

• Static site assets that had been bundled with v0.1.0; the public site now lives separately.

0.1.0 — 2025-06-05

Added

• Initial public release of the TradingAgents multi-agent trading framework: market / sentiment / news / fundamentals analysts; bull and bear researchers; trader; aggressive, conservative, and neutral risk debaters; portfolio manager. LangGraph orchestration, yfinance data, per-agent BM25 memory, single-provider OpenAI integration, interactive CLI.
