    Trying to Understand Order Handling Rules

    I'm just trying to verify the order handling rules in the managed approach for myself so I know how everything works:

    Here is the relevant section from the NT8 Help Guide:

    https://ninjatrader.com/support/help...naged+approach

    The following rules are true per unique signal name:

    Methods that generate orders to enter a position will be ignored if:
    • A position is open and an order submitted by a non market order exit method (ExitLongLimit() for example) is active and the order is used to open a position in the opposite direction
    • A position is open and an order submitted by a set method (SetStopLoss() for example) is active and the order is used to open a position in the opposite direction
    • The strategy position is flat and an order submitted by an enter method (EnterLongLimit() for example) is active and the order is used to open a position in the opposite direction
    • The entry signal name is not unique
    I've verified some of these rules, but I don't understand the part about unique signal names.

    Specifically, in my tests, multiple entries with the same signal name are allowed when it sounds like they shouldn't be.

    What is meant by the bolded item above, "The entry signal name is not unique."?

    In the following I would have expected the 2nd order to be ignored because it has the same signal name, but both orders are accepted.

    I assume I'm not interpreting the rules correctly and would appreciate any clarification.

    Code:
                
    if (Position.MarketPosition == MarketPosition.Flat && CurrentBar == 100)
    {
        EnterLongLimit(Close[0] * 0.8);
        EnterLongStopMarket(Close[0] * 1.2);
    }
    I'm using:
    • EntriesPerDirection=10
    • TraceOrders = true

    Hello Steve L,

    The signal name is the name of the order.

    If you named one order "entry1" and another order "entry2", the order handling rules would not conflict for those orders.

    Orders with unique signal names are independent.

      Thanks, Chelsea,

      What I'm saying is the opposite: the orders have the same signal name and they do not conflict. Why not?

      The rule says: "Methods that generate orders to enter a position will be ignored if: The entry signal name is not unique."

      If you prefer, we can be more explicit:

      Code:
      if (Position.MarketPosition == MarketPosition.Flat && CurrentBar == 100)
      {
         EnterLongLimit(Close[0] * 0.8, "MyEntry");
         EnterLongStopMarket(Close[0] * 1.2, "MyEntry");
      }
      The trace is summarized as follows:

      Code:
      Strategy 'Order Behavior (Managed)/171212758': Entered internal SubmitOrderManaged() method at 10/31/2018 4:00:00 PM...
      Strategy 'Order Behavior (Managed)/171212758': Entered internal SubmitOrderManaged() method at 10/31/2018 4:00:00 PM...
      Strategy 'Order Behavior (Managed)/171212758': Cancelled expired order...
      Strategy 'Order Behavior (Managed)/171212758': Cancelled expired order...
      If an order were ignored we'd see an entry with "Ignored..." But both orders are accepted. According to the rule, the second order should be ignored because it does not have a unique signal name.

        You can see that both orders have "Entry1" as their name and nothing is Ignored.

          Hello Steve L,

          Our development has let me know this is expected behavior and NinjaTrader 7 has the same behavior.

          I've submitted this as a feature request 'orders placed at the same time using the same signal name should also follow the order handling rules' which is being tracked with ID# SFT-4115.

          Please note it is up to the NinjaTrader Development to decide if or when any request will be implemented.
