First call: get_status

Always call get_status first. It returns:
  • easternTime — current Eastern time
  • marketSession — pre-market, regular, after-hours, or closed
  • ibkr.connected — whether TWS is live
If IBKR is disconnected, account/order tools will fail. Market data falls back to Yahoo.

​
Tool naming convention

Tools use snake_case names grouped by function:
  • get_* — read data
  • place_* / cancel_* — order actions
  • subscribe_* / unsubscribe_* — streaming
  • holly_* — Holly AI tools
  • session_* — session risk gate
  • exit_plan_* — exit plan management
