[fscabrera03]

Hello Everyone.
Im trying to create a StopOrder and create his Profit Target on an unmanaged approach.
But gives me this errors:

Strategy 'PruebaOnOrderFill/206666250' submitted an order that generated the following error 'Unable to submit order'. Strategy has sent cancel requests, attempted to close the position and terminated itself.

Order can't be submitted: The OCO ID 'OcoGroup1' cannot be reused. Please use a new OCO ID.

Please find attached that errors.

Here is my code:

Hi!

1) I highly recommend you start with the very well reviewed and occasionally revised Unmanaged OCO samples produced by Jim and Chelsea.

Start with these two pages

1a) Example OCO from Jim https://ninjatrader.com/support/foru...10#post1142410

1b) Unmanaged Profit Trail examples from Chelsea (cant find that page of four examples right now but ask the NT team for the link). One of the example files on that forum page is "ProfitChaseStopTrailExitOrdersExample"


2) I highly recommend reviewing last years posts about Unmanaged by Jim https://www.google.com/search?q=Ninj...4dUDCA4&uact=5

Hello fscabrera03 and HedgePlay,

The OCOIDs will need to be unique for each new pairing.
I often suggest GetAtmStrategyUniqueId() and System.Guid.NewGuid() for unique ids. Using the DateTime in the string can also make unique strings.

Below are links to ProfitChaseStopTrailUnmanagedExample_NT8 and UnmanagedOCOBracketExample_NT8.

Im still not seeing how it works OCO.
the parameter ÖCO string is to link OCO order together, so im not understanding why cannot place 3 orders (entry, stop loss and take profit) with the identic OCO string.


If I have 4 long trades and 4 short trades, how the system knows what SL or TP is for what entry trade?

Conceptually should works in a way that if entry order was filled, later if any order is filled (SL or TP) the 3 trades should close, and this link is by the oco string, is that right?

Hello fscabrera03,

You can have as many orders as you would like with the OCO group using the same OCO Id. If you want to group 4 orders that are all still in a working state, that will work.
However, you cannot use an OCO Id that has already been used on an order that has filled, rejected, or been cancelled. You will only be able to group with working orders.

Each new group must be using a new unique OCO Id. If an OCO Id is re-used, then it is group with the existing group using that Id.
