Returns 1 (true) if the current stock passed EntrySetup for the specified strategy and became an actual entry order — that is, it was not skipped due to a position or allocation limit (MaxSetups, MaxPositions, etc.)
Notes
Without Combined or Extern, IsOrder applies only to the current stock in the current strategy.
When used with Combined or Extern, IsOrder returns the count of strategies for which the current stock is a setup and has not been "skipped".
