- Remove unused `from langchain_openai import ChatOpenAI` imports from
graph/setup.py, graph/reflection.py, graph/signal_processing.py, and
agents/utils/agent_states.py. The framework supports multiple LLM
providers so these type hints were incorrect and misleading.
- Clean up agents/utils/agent_states.py: remove unused imports of
Sequence, date, timedelta, datetime, ChatOpenAI, agents star-import,
ToolNode, END, StateGraph, START (only Annotated, TypedDict, and
MessagesState are actually used).
- Fix graph/trading_graph.py _log_state(): replace hardcoded
"eval_results/" relative path with config["results_dir"] so logs land
in the same configured directory as other run outputs, regardless of
the working directory the user runs from.
- Fix dataflows/y_finance.py _get_stock_stats_bulk(): add missing
`import pandas as pd` which caused a NameError on pd.isna() during
bulk indicator calculation, silently falling back to the slower
per-day loop.
Made-with: Cursor
Add _clean_dataframe() to normalize stock DataFrames before stockstats:
coerce invalid dates/prices, drop rows missing Close, fill price gaps.
Also add on_bad_lines="skip" to all cached CSV reads.
- Replace hardcoded column indices with column name lookup
- Add mapping for all supported indicators to their expected CSV column names
- Handle missing columns gracefully with descriptive error messages
- Strip whitespace from header parsing for reliability
