Before this change, the pipeline showed a generic 'Analyzing...' spinner
for the entire multi-ticker run with no way to know which ticker was
processing or whether anything was actually working.
Changes:
- macro_bridge.py:
- run_ticker_analysis: logs '▶ Starting', '✓ complete in Xs', '✗ FAILED'
with elapsed time per ticker using logger.info/logger.error
- run_all_tickers: replaced asyncio.gather (swallows all progress) with
asyncio.as_completed + optional on_ticker_done(result, done, total)
callback; uses asyncio.Semaphore for max_concurrent control
- Added time and Callable imports
- cli/main.py run_pipeline:
- Replaced Live(Spinner) with Rich Progress bar (spinner + bar + counter
+ elapsed time)
- Prints '▷ Queued: TICKER' before analysis starts for each ticker
- on_ticker_done callback prints '✓ TICKER (N/M, Xs elapsed) → decision'
or '✗ TICKER failed ...' immediately as each ticker finishes
- Prints total elapsed time when all tickers complete
## Problem (Incident Post-mortem)
The pipeline was emitting hundreds of errors:
'Invalid number of return arguments after parsing column name: Date'
Root cause: after _clean_dataframe() lowercases all columns, stockstats.wrap()
promotes 'date' to the DataFrame index. Subsequent df['Date'] access caused
stockstats to try parsing 'Date' as a technical indicator name.
## Fixes
### 1. Fix df['Date'] stockstats bug (already shipped in prior commit)
- stockstats_utils.py + y_finance.py: use df.index.strftime() instead of
df['Date'] after wrap()
### 2. Extract _load_or_fetch_ohlcv() — single OHLCV authority
- Eliminates duplicated 30-line download+cache boilerplate in two places
- Cache filename is always derived from today's date — hardcoded stale date
'2015-01-01-2025-03-25' in local mode is gone
- Corruption/truncation detection: files <50 rows or unparseable are deleted
and re-fetched rather than silently returning bad data
- Drops on_bad_lines='skip' — malformed CSVs now raise instead of silently
dropping rows that would distort indicator calculations
### 3. YFinanceError typed exception
- Defined in stockstats_utils.py; raised instead of print()+return ''
- get_stockstats_indicator now raises YFinanceError on failure so errors
surface to callers rather than delivering empty strings to LLM agents
- interface.py route_to_vendor now catches YFinanceError alongside
AlphaVantageError and FinnhubError — failures appear in observability
telemetry and can trigger vendor fallback
### 4. Explicit date column discovery in alpha_vantage_common
- _filter_csv_by_date_range: replaced df.columns[0] positional assumption
with explicit search for 'time'/'timestamp'/'date' column
- ValueError re-raised (not swallowed) so bad API response shape is visible
### 5. Structured logging
- Replaced all print() calls in changed files with logging.getLogger()
- Added logging import + logger to alpha_vantage_common
## Tests
- tests/unit/test_incident_fixes.py: 12 new unit tests covering all fixes
(dynamic cache filename, corruption re-fetch, YFinanceError propagation,
explicit column lookup, empty download raises)
- tests/integration/test_stockstats_live.py: 11 live tests against real
yfinance API (all major indicators, weekend N/A, regression guard)
- All 70 tests pass (59 unit + 11 live integration)
- Removed unused `import time` from `tradingagents/agents/analysts/news_analyst.py`
- Verified file syntax with `py_compile`
- Confirmed that the import was successfully removed

Replaces the O(N) database operations in the `TradeExecutor`'s
`execute_decisions` SELL loop with a single `batch_remove_holdings`
call to the repository. The new repository method calculates updates
in memory, resolves duplicate operations on the same ticker, and issues
the updates via newly implemented `psycopg2.extras.execute_batch`
routines on the `SupabaseClient`.

Optimize the _percentile calculation to use heapq.nsmallest or heapq.nlargest when requesting small extreme percentiles (like 5% VaR) from large lists, falling back to sorted() only when necessary. This avoids fully sorting the entire array.

- New tradingagents/api_usage.py: Pre-run estimation of API calls per vendor
for analyze, scan, and pipeline commands. Includes Alpha Vantage tier
assessment (free: 25/day vs premium: 75/min).
- New CLI command: `estimate-api [analyze|scan|pipeline|all]`
- Enhanced observability: RunLogger.summary() now includes vendor_methods
breakdown (vendor → method → call count)
- Enhanced CLI output: All 3 command summaries (analyze, scan, pipeline)
now show per-vendor breakdown and Alpha Vantage assessment after runs
- 32 new tests in tests/unit/test_api_usage.py

- Create docs/FINANCIAL_TOOLS_ANALYSIS.md with comprehensive 4-point analysis:
1. Implementation accuracy review for all indicators and metrics
2. Library assessment (stockstats vs TA-Lib vs pandas-ta)
3. Alpha Vantage debate (local calc vs API-fetched)
4. Data flow & API mapping for every financial tool
- Fix off-by-one in ttm_analysis.py: YoY revenue used quarterly[-4]
(3 quarters back) instead of quarterly[-5] (4 quarters = 1 year back)
- Add test_revenue_yoy_is_four_quarters_back test to validate the fix

- Added edge case test for `_find_col` in `tests/unit/test_ttm_analysis.py` (from PR #56).
- Enhanced `_clean_dataframe` in `tradingagents/dataflows/stockstats_utils.py` to parse dates, drop invalid rows, fill price gaps, and lowercase columns (combining PRs #58 and #60).
- Expanded the test suite in `tests/unit/test_stockstats_utils.py` to cover the new `_clean_dataframe` functionality.
