When does this happen?

IF Long-running multi-agent inference may fail or be interrupted, losing all progress.

How others solved it

THEN Enable LangGraph checkpointing (opt-in via --checkpoint flag) to save state after each node. On a crash or interruption, the next run resumes from the last successful step instead of starting over. Checkpoints are stored in per-ticker SQLite databases under ~/.tradingagents/checkpoints and are cleared automatically on successful completion.

# Run with checkpoint resume: tradingagents --checkpoint
# On resume, logs show 'Resuming from step N for <TICKER> on <date>'
