Changed

Live Data Performance

• Changed subscription timing when switching markets
  • The new symbol subscribes immediately, with no delay
  • The old symbol unsubscribes after 100ms
  • No data gap during market switching
• Changed stream availability tracking so re-subscribing is instant
• Changed unsubscribe timing so one symbol can no longer cancel another's subscription
