"""ORB Paper Trading Engine.

One engine instance is created per session per trading day.
The scheduler calls phase methods in order:
  1. run_pre_screen()    — 09:20 ET (daily bars + enrichment + quality filter)
  2. run_orb_detection() — 09:40 ET (intraday bars → candidates)
     └─ run_pre_screen 미실행 시 full fallback (daily bars도 자체 fetch)
  3. run_breakout_check() — every sim_bar_minutes from orb_end until order_timeout
  4. run_stop_check()   — every sim_bar_minutes from orb_end until 15:55 ET
  5. run_eod_exit()     — 15:55 ET
  6. run_post_close()   — 16:00 ET

Stop management logic mirrors orb_simulator.py:477-580 exactly.
