Fix: Plotting error in core/plot.py by correcting MACD Histogram column name from 'macdh_12_26_9' to 'macdhist_12_26_9'.

Fix: Final runtime errors (backtest_output NameError and TA-Lib TSI attribute error).

Fix: Unpacking error in core/train_eval.py by aligning expected return values from preprocess_data (6 values instead of 8).

Fix: Restore core/data.py from user-provided data_4.py to resolve model training feature error. Re-applied previous app.py fixes.

Fix: Model training failure by ensuring 'value' is always included as a feature in core/data.py

Fix: ImportError for 'preprocess_data' by moving the function from core/data_2.py to core/data.py and deleting data_2.py
