order ownership

[carmiFR]

Hello,

Can a strategy cancel/amend an order created by another strategy ?
More generally : is there a strict ownership of orders ?

Thanks

Hello carmiFR,

For strategies in Ninjatrader, you could think of each strategy as its own instance. each strategy manages its own orders, so it would not be able to manage another strategies orders.

Please let me know if I may be of further assistance

Hello Jesse,

Thanks for your answer.

To be more precise : I have severals strategies collaborating (via static container members and lockers). The goal here is to have more clarity in the source code ... Whatever, in some cases, a strategy can "suspend" its own activity and transfer the ownership of its working orders to other strategies. In terms of implementation, if one of these orders gets events via OnOrderUpdate, the callbacked strategy just calls OnOrderUpdate to the strategy now owning the order. Then the new owning strategy can amend or cancel the order, calling ChangeOrder or CancelOrder with the order reference.

So just to be clear : you say this have no chance to work ? Will this call Change/CancelOrder throw an exeception ? Or will these calls just be quietly ignored ?

Many thanks

Hello carmiFR,

To answer your question, Correct this would not work in Ninjatrader as this is not how strategies are designed to be run through Ninjatrader.

One way to explain this would be each strategy contains its own orders that are tied to this specific strategy. Strategies are unaware of what another strategy is doing.

As for the second question, depending on the order methods being used you could get a null object reference error, or it would just ignore it.

Please let me know if I may be of additional assistance

Hi carmiFR,

If you already have the functionality that the Strategies can communicate with another then a possible workaround could be that you create a separate strategy that has only the purpose for order handling. This means that no other strategy will initiate orders by them self. If a trigger for an order is given the strategy sends a message to the orderhandling strategy and from there this stragey manges all orders that are initiated from your other strategies.

This is just an idea, don't know if this is really possible inside NT.

Good Luck
