- **Tool execution**: Trading graph uses `ToolNode` in graph. Scanner agents use `run_tool_loop()` inline. If `bind_tools()` is used, there MUST be a tool execution path.
|
||||
- **yfinance DataFrames**: `top_companies` has ticker as INDEX, not column. Always check `.index` and `.columns`.
|
||||
- **yfinance Sector/Industry**: `Sector.overview` has NO performance data. Use ETF proxies for performance.
|
||||
- **Vendor fallback**: Functions inside `route_to_vendor` must RAISE on failure, not embed errors in return values. Catch `AlphaVantageError` (base class), not just `RateLimitError`.
|
||||
- **Vendor fallback**: Functions inside `route_to_vendor` must RAISE on failure, not embed errors in return values. Catch `(AlphaVantageError, ConnectionError, TimeoutError)`, not just `RateLimitError`.
|
||||
- **LangGraph parallel writes**: Any state field written by parallel nodes MUST have a reducer (`Annotated[str, reducer_fn]`).
|
||||
- **Ollama remote host**: Never hardcode `localhost:11434`. Use configured `base_url`.
|
||||
- **.env loading**: Check actual env var values when debugging auth. Worktree and main repo may have different `.env` files.
|
||||
- **.env loading**: `load_dotenv()` runs at module level in `default_config.py` — import-order-independent. Check actual env var values when debugging auth.
|
||||
- **Rate limiter locks**: Never hold a lock during `sleep()` or IO. Release, sleep, re-acquire.
|
||||
- **Config fallback keys**: `llm_provider` and `backend_url` must always exist at top level — `scanner_graph.py` and `trading_graph.py` use them as fallbacks.

|
||||
deep_think: deepseek/deepseek-r1-0528 via OpenRouter
|
||||
Per-tier provider overrides in `tradingagents/default_config.py`:
|
||||
- Each tier (`quick_think`, `mid_think`, `deep_think`) can have its own `_llm_provider` and `_backend_url`
|
||||
- Falls back to top-level `llm_provider` and `backend_url` when per-tier values are None
|
||||
- All config values overridable via `TRADINGAGENTS_<KEY>` env vars
|
||||
- Keys for LLM providers: `.env` file (e.g., `OPENROUTER_API_KEY`, `ALPHA_VANTAGE_API_KEY`)
|
||||
|
||||
### Env Var Override Convention
|
||||
|
||||
```env
|
||||
# Pattern: TRADINGAGENTS_<UPPERCASE_KEY>=value
|
||||
TRADINGAGENTS_LLM_PROVIDER=openrouter
|
||||
TRADINGAGENTS_DEEP_THINK_LLM=deepseek/deepseek-r1-0528
|
||||
TRADINGAGENTS_MAX_DEBATE_ROUNDS=3
|
||||
TRADINGAGENTS_VENDOR_SCANNER_DATA=alpha_vantage
|
||||
```
|
||||
|
||||
Config: `tradingagents/default_config.py` (per-tier `_llm_provider` keys)
|
||||
Keys: `.env` file (`OPENROUTER_API_KEY`, `ALPHA_VANTAGE_API_KEY`)
|
||||
Empty or unset vars preserve the hardcoded default. `None`-default fields (like `mid_think_llm`) stay `None` when unset, preserving fallback semantics.

## Decision 007: .env Loading Strategy
|
||||
|
||||
**Date**: 2026-03-17
|
||||
**Status**: Implemented ✅
|
||||
**Status**: Superseded by Decision 008 ⚠️
|
||||
|
||||
**Context**: `load_dotenv()` loads from CWD. 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. The CLI-level `load_dotenv()` in `main.py` is now defense-in-depth only.
|
||||
|
||||

|
||||
|
||||
## Decision 008: Environment Variable Config Overrides
|
||||
|
||||
**Date**: 2026-03-17
|
||||
**Status**: Implemented ✅
|
||||
|
||||
**Context**: `DEFAULT_CONFIG` hardcoded all values (LLM providers, models, vendor routing, debate rounds). 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_<KEY>` 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_<KEY>` 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.

||||

||||

## 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`.
|
||||

||||

|
|||
|
||||
**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**: Works currently because per-tier providers are always set. But it's a latent bug.
|
||||
**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`.
|
||||
|
||||
**TODO**: Add a safe fallback or remove the dead code path.
|
||||
**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.

## Milestone: Env Var Config Overrides ✅ COMPLETE (PR #9)
|
||||
|
||||
All `DEFAULT_CONFIG` values are now overridable via `TRADINGAGENTS_<KEY>` environment variables without code changes. This resolves the latent bug from Mistake #9 (missing top-level `llm_provider`).
|
||||
|
||||
### What Changed
|
||||
|
||||
| Component | Detail |
|
||||
|-----------|--------|
|
||||
| `default_config.py` | `load_dotenv()` at module level + `_env()`/`_env_int()` helpers |
|
||||
| Top-level fallback keys | Restored `llm_provider` and `backend_url` (defaults: `"openai"`, `"https://api.openai.com/v1"`) |
|
||||
| Per-tier overrides | All `None` by default — fall back to top-level when not set via env |
|
||||
| Integer config keys | `max_debate_rounds`, `max_risk_discuss_rounds`, `max_recur_limit` use `_env_int()` |
|
||||
| Data vendor keys | `data_vendors.*` overridable via `TRADINGAGENTS_VENDOR_<CATEGORY>` |
|
||||
| `.env.example` | Complete reference of all overridable settings |
|
||||
| `python-dotenv` | Added to `pyproject.toml` as explicit dependency |
|
||||
| Tests | 15 new tests in `tests/test_env_override.py` |
