Date: Tue, 17 Mar 2026 14:25:10 +0000 Subject: [PATCH 04/12] fix: allow .env variables to override DEFAULT_CONFIG values Merged origin/main and resolved all 8 conflicting files: - CLAUDE.md: merged MISTAKES.md ref + Project Tracking section + env override docs - cli/main.py: kept top-level json import, kept try/except in run_pipeline - tool_runner.py: kept descriptive comments for MAX_TOOL_ROUNDS - alpha_vantage_common.py: kept thread-safe rate limiter, robust error handling - interface.py: kept broader exception catch (AlphaVantageError + ConnectionError + TimeoutError) - default_config.py: kept _env()/_env_int() env var overrides with load_dotenv() at module level - scanner_graph.py: kept debug mode fix (stream for debug, invoke for result) - macro_bridge.py: kept get_running_loop() over deprecated get_event_loop() Co-authored-by: aguzererler <6199053+aguzererler@users.noreply.github.com> --- .env.example | 19 ++- CLAUDE.md | 15 +-- cli/main.py | 21 ++--

Sep 17 00:00:00 2001 From: Ahmet Guzererler Date: Tue, 17 Mar 2026 17:14:11 +0100 Subject: [PATCH 09/12] feat: add agentic memory scaffold and migrate tracking files to docs/agent/ Migrate DECISIONS.md, MISTAKES.md, PROGRESS.md, agents/, plans/, and tradingagents/llm_clients/TODO.md into a structured docs/agent/ scaffold with ADR-style decisions, plans, templates, and a live state tracker. This gives agent workflows a standard memory structure for decisions, plans, logs, and session continuity via CURRENT_STATE.md.

Scanner agents are simpler single-pass nodes — no ToolNode in the graph. When the LLM returned tool_calls, nobody executed them, resulting in empty reports. - -**Decision**: Created `tradingagents/agents/utils/tool_runner.py` with `run_tool_loop()` that runs an inline tool execution loop within each scanner agent node: -1.

When running from a git worktree, the worktree `.env` may have placeholder values while the main repo `.env` has real keys. - -**Decision**: `cli/main.py` calls `load_dotenv()` (CWD) then `load_dotenv(Path(__file__).parent.parent / ".env")` as fallback. The worktree `.env` was also updated with real API keys. - -**Note for future**: If `.env` issues recur, check which `.env` file is being picked up. The worktree and main repo each have their own `.env`. - -**Update**: Decision 008 moves `load_dotenv()` into `default_config.py` itself, making it import-order-independent.

Users had to edit `default_config.py` to change any setting. The `load_dotenv()` call in `cli/main.py` ran *after* `DEFAULT_CONFIG` was already evaluated at import time, so env vars like `TRADINGAGENTS_LLM_PROVIDER` had no effect. This also created a latent bug (Mistake #9): `llm_provider` and `backend_url` were removed from the config but `scanner_graph.py` still referenced them as fallbacks. - -**Decision**: -1. **Module-level `.env` loading**: `default_config.py` calls `load_dotenv()` at the top of the module, before `DEFAULT_CONFIG` is evaluated. Loads from CWD first, then falls back to project root (`Path(__file__).resolve().parent.parent / ".env"`). -2. **`_env()` / `_env_int()` helpers**: Read `TRADINGAGENTS_` from environment. Return the hardcoded default when the env var is unset or empty (preserving `None` semantics for per-tier fallbacks). -3. **Restored top-level keys**: `llm_provider` (default: `"openai"`) and `backend_url` (default: `"https://api.openai.com/v1"`) restored as env-overridable keys. Resolves Mistake #9. -4. **All config keys overridable**: LLM models, providers, backend URLs, debate rounds, data vendor categories — all follow the `TRADINGAGENTS_` pattern. -5. **Explicit dependency**: Added `python-dotenv>=1.0.0` to `pyproject.toml` (was used but undeclared). - -**Naming convention**: `TRADINGAGENTS_` prefix + uppercase config key. Examples: -``` -TRADINGAGENTS_LLM_PROVIDER=openrouter -TRADINGAGENTS_DEEP_THINK_LLM=deepseek/deepseek-r1-0528 -TRADINGAGENTS_MAX_DEBATE_ROUNDS=3 -TRADINGAGENTS_VENDOR_SCANNER_DATA=alpha_vantage -``` - -**Files changed**: -- `tradingagents/default_config.py` — core implementation -- `main.py` — moved `load_dotenv()` before imports (defense-in-depth) -- `pyproject.toml` — added `python-dotenv>=1.0.0` -- `.env.example` — documented all overrides -- `tests/test_env_override.py` — 15 tests - -**Alternative considered**: YAML/TOML config file. Rejected — env vars are simpler, work with Docker/CI, and don't require a new config file format. - ---- - -## Decision 009: Thread-Safe Rate Limiter for Alpha Vantage - -**Date**: 2026-03-17 -**Status**: Implemented ✅ - -**Context**: The Alpha Vantage rate limiter in `alpha_vantage_common.py` initially slept *inside* the lock when re-checking the rate window. This blocked all other threads from making API requests during the sleep period, effectively serializing all AV calls. - -**Decision**: Two-phase rate limiting: -1. **First check**: Acquire lock, check timestamps, release lock, sleep if needed. -2. **Re-check loop**: Acquire lock, re-check timestamps. If still over limit, release lock *before* sleeping, then retry. Only append timestamp and break when under the limit. - -This ensures the lock is never held during `sleep()` calls. - -**File**: `tradingagents/dataflows/alpha_vantage_common.py` - ---- - -## Decision 010: Broader Vendor Fallback Exception Handling - -**Date**: 2026-03-17 -**Status**: Implemented ✅ - -**Context**: `route_to_vendor()` only caught `AlphaVantageError` for fallback. But network issues (`ConnectionError`, `TimeoutError`) from the `requests` library wouldn't trigger fallback — they'd crash the pipeline instead. - -**Decision**: Broadened the catch in `route_to_vendor()` to `(AlphaVantageError, ConnectionError, TimeoutError)`. Similarly, `_make_api_request()` now catches `requests.exceptions.RequestException` as a general fallback and wraps `raise_for_status()` in a try/except to convert HTTP errors to `ThirdPartyError`. - -**Files**: `tradingagents/dataflows/interface.py`, `tradingagents/dataflows/alpha_vantage_common.py` diff --git a/MISTAKES.md b/MISTAKES.md deleted file mode 100644 index b296dc0e..00000000 --- a/MISTAKES.md +++ /dev/null @@ -1,122 +0,0 @@ -# Mistakes & Lessons Learned - -Documenting bugs and wrong assumptions to avoid repeating them. - ---- - -## Mistake 1: Scanner agents had no tool execution - -**What happened**: All 4 scanner agents (geopolitical, market movers, sector, industry) used `llm.bind_tools(tools)` but only checked `if len(result.tool_calls) == 0: report = result.content`. When the LLM chose to call tools (which it always does when tools are available), nobody executed them. Reports were always empty strings. - -**Root cause**: Copied the pattern from existing analysts (`news_analyst.py`) without realizing that the trading graph has separate `ToolNode` graph nodes that handle tool execution in a routing loop. The scanner graph has no such nodes. - -**Fix**: Created `tool_runner.py` with `run_tool_loop()` that executes tools inline within the agent node. - -**Lesson**: When an LLM has `bind_tools`, there MUST be a tool execution mechanism — either graph-level `ToolNode` routing or inline execution. Always verify the tool execution path exists. - ---- - -## Mistake 2: Assumed yfinance `Sector.overview` has performance data - -**What happened**: Wrote `get_sector_performance_yfinance` using `yf.Sector("technology").overview["oneDay"]` etc. This field doesn't exist — `overview` only returns metadata (companies_count, market_cap, industries_count). - -**Root cause**: Assumed the yfinance Sector API mirrors the Yahoo Finance website which shows performance data. It doesn't. - -**Fix**: Switched to SPDR ETF proxy approach — download ETF prices and compute percentage changes. - -**Lesson**: Always test data source APIs interactively before writing agent code. Run `python -c "import yfinance as yf; print(yf.Sector('technology').overview)"` to see actual data shape. - ---- - -## Mistake 3: yfinance `top_companies` — ticker is the index, not a column - -**What happened**: Used `row.get('symbol')` to get ticker from `top_companies` DataFrame. Always returned N/A. - -**Root cause**: The DataFrame has `index.name = 'symbol'` — tickers are the index, not a column. The actual columns are `['name', 'rating', 'market weight']`. - -**Fix**: Changed to `for symbol, row in top_companies.iterrows()`. - -**Lesson**: Always inspect DataFrame structure with `.head()`, `.columns`, and `.index` before writing access code. - ---- - -## Mistake 4: Hardcoded Ollama localhost URL - -**What happened**: `openai_client.py` had `base_url = "http://localhost:11434/v1"` hardcoded for Ollama provider, ignoring the `self.base_url` config. User's Ollama runs on `192.168.50.76:11434`. - -**Fix**: Changed to `host = self.base_url or "http://localhost:11434"` with `/v1` suffix appended. - -**Lesson**: Never hardcode URLs. Always use the configured value with a sensible default. - ---- - -## Mistake 5: Only caught `RateLimitError` in vendor fallback - -**What happened**: `route_to_vendor()` only caught `RateLimitError`. Alpha Vantage demo key returns "Information" responses (not rate limit errors) and other `AlphaVantageError` subtypes. Fallback to yfinance never triggered. - -**Fix**: Broadened catch to `AlphaVantageError` (base class). - -**Lesson**: Fallback mechanisms should catch the broadest reasonable error class, not just specific subtypes. - ---- - -## Mistake 6: AV scanner functions silently caught errors - -**What happened**: `get_sector_performance_alpha_vantage` and `get_industry_performance_alpha_vantage` caught exceptions internally and embedded error strings in the output (e.g., `"Error: ..."` in the result dict). `route_to_vendor` never saw an exception, so it never fell back to yfinance. - -**Fix**: Made both functions raise `AlphaVantageError` when ALL queries fail, while still tolerating partial failures. - -**Lesson**: Functions used inside `route_to_vendor` MUST raise exceptions on total failure — embedding errors in return values defeats the fallback mechanism. - ---- - -## Mistake 7: LangGraph concurrent write without reducer - -**What happened**: Phase 1 runs 3 scanners in parallel. All write to `sender` (and other shared fields). LangGraph raised `INVALID_CONCURRENT_GRAPH_UPDATE` because `ScannerState` had no reducer for concurrent writes. - -**Fix**: Added `_last_value` reducer via `Annotated[str, _last_value]` to all ScannerState fields. - -**Lesson**: Any LangGraph state field written by parallel nodes MUST have a reducer. Use `Annotated[type, reducer_fn]`. - ---- - -## Mistake 8: .env file had placeholder values in worktree - -**What happened**: Created `.env` in worktree with template values (`your_openrouter_key_here`). User's real keys were only in main repo's `.env`. `load_dotenv()` loaded the worktree placeholder, so OpenRouter returned 401. - -**Root cause**: Created `.env` template during setup without copying real keys. `load_dotenv()` with `override=False` (default) keeps the first value found. - -**Fix**: Updated worktree `.env` with real keys. Also added fallback `load_dotenv()` call for project root. - -**Lesson**: When creating `.env` files, always verify they have real values, not placeholders. When debugging auth errors, first check `os.environ.get('KEY')` to see what value is actually loaded. - ---- - -## Mistake 9: Removed top-level `llm_provider` but code still references it - -**What happened**: Removed `llm_provider` from `default_config.py` (since we have per-tier providers). But `scanner_graph.py` line 78 does `self.config.get(f"{tier}_llm_provider") or self.config["llm_provider"]` — would crash if per-tier provider is ever None. - -**Status**: ✅ RESOLVED in PR #9. Top-level `llm_provider` (default: `"openai"`) and `backend_url` (default: `"https://api.openai.com/v1"`) restored as env-overridable config keys. Per-tier providers safely fall back to these when `None`. - -**Lesson**: Always preserve fallback keys that downstream code depends on. When refactoring config, grep for all references before removing keys. - ---- - -## Mistake 10: Rate limiter held lock during sleep - -**What happened**: The Alpha Vantage rate limiter's re-check path in `_rate_limited_request()` called `_time.sleep(extra_sleep)` while holding `_rate_lock`. This blocked all other threads from making API requests during the sleep period, effectively serializing all AV calls even though the pipeline runs parallel scanner agents. - -**Root cause**: Initial implementation only had one lock section. When the re-check-after-sleep pattern was added to prevent race conditions, the sleep was left inside the `with _rate_lock:` block. - -**Fix**: Restructured the re-check as a `while True` loop that releases the lock before sleeping: -```python -while True: - with _rate_lock: - if len(_call_timestamps) < _RATE_LIMIT: - _call_timestamps.append(_time.time()) - break - extra_sleep = 60 - (now - _call_timestamps[0]) + 0.1 - _time.sleep(extra_sleep) # ← outside lock -``` - -**Lesson**: Never hold a lock during a sleep/IO operation. Always release the lock, perform the blocking operation, then re-acquire. diff --git a/PROGRESS.md b/PROGRESS.md deleted file mode 100644 index 229aaab0..00000000 --- a/PROGRESS.md +++ /dev/null @@ -1,108 +0,0 @@ -# Scanner Pipeline — Progress Tracker - -## Milestone: End-to-End Scanner ✅ COMPLETE - -The 3-phase scanner pipeline runs successfully from `python -m cli.main scan --date 2026-03-17`. - -### What Works - -| Component | Status | Notes | -|-----------|--------|-------| -| Phase 1: Geopolitical Scanner | ✅ | Ollama/qwen3.5:27b, uses `get_topic_news` | -| Phase 1: Market Movers Scanner | ✅ | Ollama/qwen3.5:27b, uses `get_market_movers` + `get_market_indices` | -| Phase 1: Sector Scanner | ✅ | Ollama/qwen3.5:27b, uses `get_sector_performance` (SPDR ETF proxies) | -| Phase 2: Industry Deep Dive | ✅ | Ollama/qwen3.5:27b, uses `get_industry_performance` + `get_topic_news` | -| Phase 3: Macro Synthesis | ✅ | OpenRouter/DeepSeek R1, pure LLM synthesis (no tools) | -| Parallel fan-out (Phase 1) | ✅ | LangGraph with `_last_value` reducers | -| Tool execution loop | ✅ | `run_tool_loop()` in `tool_runner.py` | -| Data vendor fallback | ✅ | AV → yfinance fallback on `AlphaVantageError`, `ConnectionError`, `TimeoutError` | -| CLI `--date` flag | ✅ | `python -m cli.main scan --date YYYY-MM-DD` | -| .env loading | ✅ | `load_dotenv()` at module level in `default_config.py` — import-order-independent | -| Env var config overrides | ✅ | All `DEFAULT_CONFIG` keys overridable via `TRADINGAGENTS_` env vars | -| Tests (38 total) | ✅ | 14 original + 9 scanner fallback + 15 env override tests | - -### Output Quality (Sample Run 2026-03-17) - -| Report | Size | Content | -|--------|------|---------| -| geopolitical_report | 6,295 chars | Iran conflict, energy risks, central bank signals | -| market_movers_report | 6,211 chars | Top gainers/losers, volume anomalies, index trends | -| sector_performance_report | 8,747 chars | Sector rotation analysis with ranked table | -| industry_deep_dive_report | — | Ran but was sparse (Phase 1 reports were the primary context) | -| macro_scan_summary | 10,309 chars | Full synthesis with stock picks and JSON structure | - -### Files Created/Modified - -**New files:** -- `tradingagents/agents/utils/tool_runner.py` — inline tool execution loop -- `tradingagents/agents/utils/scanner_states.py` — ScannerState with reducers -- `tradingagents/agents/utils/scanner_tools.py` — LangChain tool wrappers for scanner data -- `tradingagents/agents/scanners/` — all 5 scanner agent modules -- `tradingagents/graph/scanner_graph.py` — ScannerGraph orchestrator -- `tradingagents/graph/scanner_setup.py` — LangGraph workflow setup -- `tradingagents/dataflows/yfinance_scanner.py` — yfinance data for scanner -- `tradingagents/dataflows/alpha_vantage_scanner.py` — Alpha Vantage data for scanner -- `tradingagents/pipeline/macro_bridge.py` — scan → filter → per-ticker analysis bridge -- `tests/test_scanner_fallback.py` — 9 fallback tests -- `tests/test_env_override.py` — 15 env override tests - -**Modified files:** -- `tradingagents/default_config.py` — env var overrides via `_env()`/`_env_int()` helpers, `load_dotenv()` at module level, restored top-level `llm_provider` and `backend_url` keys -- `tradingagents/llm_clients/openai_client.py` — Ollama remote host support -- `tradingagents/dataflows/interface.py` — broadened fallback catch to `(AlphaVantageError, ConnectionError, TimeoutError)` -- `tradingagents/dataflows/alpha_vantage_common.py` — thread-safe rate limiter (sleep outside lock), broader `RequestException` catch, wrapped `raise_for_status` -- `tradingagents/graph/scanner_graph.py` — debug mode fix (stream for debug, invoke for result) -- `tradingagents/pipeline/macro_bridge.py` — `get_running_loop()` over deprecated `get_event_loop()` -- `cli/main.py` — `scan` command with `--date` flag, `try/except` in `run_pipeline`, `.env` loading fix -- `main.py` — `load_dotenv()` before tradingagents imports -- `pyproject.toml` — `python-dotenv>=1.0.0` dependency declared -- `.env.example` — documented all `TRADINGAGENTS_*` overrides and `ALPHA_VANTAGE_API_KEY` - ---- - -## Milestone: Env Var Config Overrides ✅ COMPLETE (PR #9) - -All `DEFAULT_CONFIG` values are now overridable via `TRADINGAGENTS_` environment variables without code changes.

Focus on leading indicators (PMIs, yield curve shape, credit impulse) rather than lagging GDP prints. -- **Inflation**: Is inflation above/below target, rising/falling, and is it demand-pull or cost-push? Assess both headline and core measures. Note divergences between regions (US, EU, EM). -- **Monetary Policy Stance**: Where are major central banks (Fed, ECB, BOJ, PBoC, BOE) in their cycles? Are real rates positive or negative? Is the market pricing hikes, cuts, or a pause? How does the dot plot or forward guidance diverge from market pricing? -- **Credit Conditions**: Are credit spreads (IG, HY, EM sovereign) tightening or widening? Is there evidence of financial stress or easy credit availability? Monitor the VIX, MOVE index, and TED spread as systemic risk gauges. -- **Geopolitical and Structural Risk**: Identify any active geopolitical flashpoints, trade policy shifts, energy supply disruptions, or regulatory changes that create asymmetric sector-level risk. - -### Step 2 — Cross-Asset Chart Reading -Systematically scan major global market indices and instruments: - -- **Global Equity Indices**: S&P 500, Nasdaq 100, Russell 2000, MSCI World, MSCI EM, Euro Stoxx 50, Nikkei 225, Hang Seng. Note relative strength, breadth, and divergences between regions and between large/small cap. -- **Fixed Income**: 2Y, 10Y, 30Y US Treasury yields; yield curve slope (2s10s, 3m10y); TIPS breakevens (inflation expectations); IG and HY credit spreads. -- **Commodities**: Brent/WTI crude, natural gas, gold, copper (as a growth proxy), agricultural commodities. Note supply/demand drivers and geopolitical factors. -- **Currencies**: DXY (USD index), EUR/USD, USD/JPY, USD/CNH, AUD/USD (risk-on proxy). Currency strength/weakness has direct implications for multinational earnings and EM capital flows. -- **Volatility**: VIX level and term structure, MOVE index. High volatility regimes compress valuations; low volatility supports risk assets. - -Identify: trend direction, momentum shifts, breakouts/breakdowns from key levels, and divergences between correlated instruments that may signal regime change. - -### Step 3 — Sector and Industry Rotation Analysis -Map the macro regime findings onto sector implications: - -- **Rate-sensitive sectors** (Utilities, REITs, Financials): How are they responding to rate dynamics? -- **Cyclical sectors** (Industrials, Materials, Consumer Discretionary, Energy): Are they outperforming defensives, suggesting growth confidence? -- **Defensive sectors** (Consumer Staples, Health Care, Utilities): Are they seeing inflows, suggesting risk-off rotation? -- **Growth sectors** (Technology, Communication Services): How are long-duration assets responding to real rate changes? -- **Commodity-linked sectors** (Energy, Materials, Agriculture): What are supply/demand dynamics signaling? - -Identify sectors with: -- Strong relative price momentum vs. the broad index -- Positive earnings revision momentum -- Macro tailwinds aligned with the current regime -- Unusual options activity or institutional positioning signals -- Theme-driven catalysts (AI infrastructure buildout, energy transition, reshoring, aging demographics, etc.) - -### Step 4 — Key Metrics Identification -Based on the macro regime and sector findings, specify the metrics most relevant for current conditions. Examples by regime: - -- **Stagflationary environment**: Focus on pricing power metrics, real earnings growth, commodity cost pass-through, and wage inflation data. -- **Rate-cutting cycle**: Focus on duration sensitivity, housing starts, consumer credit growth, and P/E multiple expansion potential. -- **Risk-off / credit stress**: Focus on cash conversion cycles, leverage ratios (Net Debt/EBITDA), interest coverage, and free cash flow yield. -- **Growth acceleration**: Focus on revenue growth acceleration, capex cycles, PMI new orders sub-indices, and inventory restocking signals. - -Always flag: the yield curve shape, P/E vs. earnings yield vs. real bond yield relationship, and any sentiment extremes (AAII survey, put/call ratios, fund manager surveys). - -### Step 5 — Synthesis and Prioritization -Combine all findings into a structured output (see Output Format below). Apply the following prioritization logic: - -- Weight sectors/themes higher if multiple independent signals (price, fundamental, macro, sentiment) converge. -- Flag any high-conviction macro calls where the evidence is unambiguous. -- Clearly distinguish between high-conviction and speculative/watch-list observations. -- Identify what would change your view (key risk scenarios and trigger events to monitor). - ---- - -## Quality Standards - -- Every claim must be grounded in observable data or a named indicator — avoid vague assertions. -- Distinguish between lagging indicators (GDP, CPI), coincident indicators (industrial production, payrolls), and leading indicators (PMIs, yield curve, credit spreads). Weight leading indicators more heavily for forward-looking conclusions. -- Acknowledge uncertainty and competing narratives explicitly. Markets are probabilistic, not deterministic. -- Do not anchor on a single data point. Require convergence across multiple independent signals before making high-conviction calls. -- Be explicit about time horizons: near-term (1-4 weeks), medium-term (1-3 months), structural (6+ months). -- Avoid recency bias. A single strong data print does not change a trend; assess the direction and rate of change over multiple periods. - ---- - -## Output Format - -Structure every analysis using the following sections.

Use `black`-compatible formatting (88-char line limit). -- All public functions and classes must have Google-style docstrings including `Args`, `Returns`, and `Raises` sections. -- Use full type annotations everywhere: function signatures, class attributes, local variables where it aids readability. -- Prefer `pathlib.Path` over `os.path` for filesystem operations, consistent with the project's existing usage. -- Use `dataclasses` or `TypedDict` for structured data rather than plain dicts when the schema is known. - -**Imports** -- Group imports: stdlib, third-party, local — separated by blank lines. -- Never use wildcard imports (`from module import *`) except where the existing codebase already does so (e.g., `from tradingagents.agents import *`). -- Prefer explicit imports to make dependencies traceable during audits. - -**Error Handling** -- Wrap all external API calls (broker APIs, market data fetches) in try/except with specific exception types. -- Log errors with structured context (ticker, timestamp, operation) rather than bare `print` statements. Use Python's `logging` module. -- Never silently swallow exceptions in trading logic. A missed exception in an order submission is a real financial risk. - -**Testing** -- Write `pytest`-compatible unit tests for all new modules. Use `pytest-mock` for mocking external API calls. -- Separate pure calculation logic (indicator math, signal generation) from I/O so it is easily unit-tested. -- Include at least one edge-case test: empty data, single-row DataFrames, NaN-heavy series. - -## Trading Domain Standards - -**Data Handling** -- Always validate that OHLCV data is sorted ascending by timestamp before any calculation. -- Detect and handle forward-looking bias: never use future data in signal computation. When working with pandas, use `.shift()` correctly and be explicit about alignment. -- Normalize timezone handling: convert all timestamps to UTC at ingestion; store and compare in UTC. -- For the TradingAgents vendor abstraction, new data sources must implement the same return schema as existing tools in `agent_utils.py` (typically a dict or pandas DataFrame matching the established columns). - -**Risk Controls** -- Every order-generation function must accept and enforce a `max_position_size` parameter. -- Position sizing logic must be separate from signal logic — never hardcode notional sizes in strategy code. -- Include pre-trade checks: available capital, existing exposure, daily loss limits. Make these explicit parameters, not magic numbers. -- Stop-loss and take-profit levels must be validated to be on the correct side of the entry price before submission. - -**Backtesting** -- Clearly distinguish between vectorized backtesting (VectorBT, pandas-based) and event-driven backtesting (Backtrader, Zipline). Use vectorized for rapid signal research; use event-driven for realistic execution simulation. -- Account for transaction costs, slippage, and bid-ask spread in every backtest. If the user does not specify, default to a conservative estimate (0.05% per side for equities, 0.1% for crypto). -- Warn explicitly if backtest results show Sharpe > 3 or annualized returns > 100% — these almost always indicate look-ahead bias or overfitting. -- Do not use `pandas.DataFrame.resample` with `label='right'` on OHLCV data without explaining the survivorship/look-ahead implications. - -**Live Trading Considerations** -- Clearly separate code paths for paper trading and live trading. Use a `dry_run: bool` flag pattern. -- All order submissions must be idempotent where the API supports client order IDs. -- Rate-limit API calls explicitly. Use `time.sleep` or `asyncio.sleep` with documented rate limit sources. -- For async integrations (WebSocket feeds, async broker clients), use `asyncio` with proper cancellation handling — never use threading for new code unless the library forces it. - -## Methodology: Translating Trader Requirements to Code - -When a trader describes a strategy in natural language, follow this process: - -1. **Restate the strategy** in precise mathematical terms before writing any code. Confirm the entry condition, exit condition, position sizing rule, and risk limit. -2. **Identify the required data inputs**: which price series, which timeframe, which fundamental or alternative data. -3. **Map to the TradingAgents data layer**: identify which existing `agent_utils` tools provide this data, or specify what new tool is needed. -4. **Design the module interface first**: define function signatures and types before implementing the body. -5. **Implement in layers**: data fetching → indicator calculation → signal generation → position sizing → order construction. Keep each layer independently testable. -6. **Add guardrails**: parameter validation at the top of each function, sensible defaults, clear docstrings for every parameter. - -## Output Format - -**For new code modules**, always provide: -- Full file path relative to the project root (e.g., `tradingagents/strategies/pairs_trading.py`). -- Complete, runnable code — not pseudocode or skeletons unless the user explicitly asks for a design sketch. -- A brief usage example in a docstring or `if __name__ == "__main__"` block. -- A note on where to hook the module into the existing graph or config if applicable. - -**For code reviews**, structure feedback as: -- **Critical**: Issues that could cause incorrect trades, financial loss, or data corruption. Must be fixed before production. -- **Major**: Bugs or design problems that will cause failures under realistic conditions. -- **Minor**: Style, naming, or efficiency issues that reduce maintainability. -- **Suggestions**: Optional improvements, alternative approaches, or library recommendations. - -**For API integrations**, always include: -- Authentication setup with environment variable conventions consistent with the project (check existing `.env` patterns). -- The exact return schema the tool function will produce, showing column names and dtypes for DataFrames. -- A note on the provider's rate limits and how the implementation respects them. - -## Domain Knowledge Reference - -**Key libraries and their roles in this project:** -- `langgraph` / `langchain`: agent graph orchestration — do not bypass the established `ToolNode` pattern for new tools. -- `yfinance`: primary free market data source; use `yf.Ticker(ticker).history(period, interval)` pattern. -- `pandas`: core data manipulation; always check `.empty` before operating on fetched DataFrames. -- `numpy`: numerical computation; prefer vectorized operations over row-wise loops for performance. -- `statsmodels`: time series econometrics (ADF test, ARIMA, cointegration). -- `scikit-learn`: ML pipeline construction; always use `Pipeline` to prevent data leakage in feature scaling. -- `TA-Lib` / `pandas-ta`: technical indicators; when both are available, prefer `pandas-ta` for pure-Python portability. - -**Order types to know:** -- Market, Limit, Stop-Market, Stop-Limit, Trailing Stop, OCO (One-Cancels-Other), Bracket orders. -- Always ask which order types the target broker API supports before designing execution logic. - -**Greeks (for options work):** -- Delta, Gamma, Theta, Vega, Rho. Use `mibian` or `py_vollib` for Black-Scholes calculations. Warn when applying BSM to American options. - -## Edge Cases and Escalation - -- If a request involves submitting real orders to a live broker, explicitly flag all code as requiring human review before execution and recommend paper trading validation first. -- If asked to implement a strategy that structurally cannot be backtested without look-ahead bias (e.g., uses end-of-day prices to generate intraday signals), state this clearly and propose a corrected formulation. -- If a requested third-party library is not already in the project's dependencies, name it, provide the `pip install` command, and note it should be added to `pyproject.toml` under `[project.dependencies]`. -- If the user's requirement is ambiguous about timeframe, frequency, or asset class, ask one focused clarifying question before writing code. Do not guess on parameters that directly affect trading logic. -- For any cryptographic key or API secret handling, always recommend environment variables and never suggest hardcoding credentials, even in examples. diff --git a/docs/agent/CURRENT_STATE.md b/docs/agent/CURRENT_STATE.md new file mode 100644 index 00000000..7c78ea16 --- /dev/null +++ b/docs/agent/CURRENT_STATE.md @@ -0,0 +1,17 @@ +# Current Milestone + +Scanner pipeline is feature-complete and running end-to-end.

This broke test_industry_perf_falls_back_to_yfinance which asserts N/A count < 5. Now both download and display use head(10) for consistency.
