Solutions

1. Reduce the sell quantity to at most the available position.
2. Check prior trades for the symbol to ensure buys were recorded before sells.
3. Correct the trade date/order if sells are being applied before their corresponding buys.

When it happens

Trigger: Thrown at src/services/portfolio_service.py:691 when the library encounters an invalid state.

Common situations: Raised when a sell request exceeds the available quantity for the symbol; occurs when the requested sell amount is larger than the computed holdings, preventing overselling.
