OrderId vs. Token

[terenyi]

Hi!

What is the difference between OrderId and Token in IOrder?

Thanks!

OrderID = A string representing the broker issued order id value (this value can change)

Token = A string representing the unique id of an order (Internal NT Token so won't change from external factors like brokerages changing it on you).

Thanks Josh!

Is this the same for NT 7? On NT 7 it seems the token is now the same as the OrderId..

kashmir,

No, not the same. Token is not unique in NT7. Please see here for more information: http://www.ninjatrader.com/support/h...nt7/iorder.htm

To check for equality you can just directly compare the IOrder objects now instead of trying to rely on ID.

Thanks for the quick reply Josh,

Do you know why this was changed from the previous version?

I used to use .Token to compare all my orders. Why do orders now have .orderid and .token if they are the same?

Thanks

kashmir,

OrderId and Token are not the same. Token is internally generated ID and can change as the strategy switches from historical to live. OrderId is whatever comes from the brokerage.

There were limitations with the old approach which have been improved upon in 7 which now allows one to directly compare IOrder objects for equality. One of the things that was required to achieve this was that Token would not necessarily stay the same throughout the entire lifespan of an order anymore.
