Can a Strategy close another account's position?

Can a Strategy close another account's position?

i.e.
I have
Strategy A trading on Sim101
Strategy B trading on Sim102

When the conditions are met,
Can Strategy A be programmed to close positions on Sim102?

Hello johnnybegoode,

Through the strategy class provisions no, a strategy is only able to trade the account selected for the strategy. But using the addon approach you can send orders to any account in any script including a strategy.

Below are public links to the help guide on the addon approach of sending an order.

This is how I close all the positions on "Strategy B" which is trading on "Sim102"
Can this line be replicated using the addon approach:

ExitShort(0,[B]Position.Quantity[/B],"EXIT SHORT EURUSD (ProfitTarget)","");

How could I replicate the above onto "Strategy A" which is attached to account "Sim101" to exits all positions of "Sim102"?

Account b = Account.All.First(t => t.Name == "Sim102");

Order closeAll_102 = null;
closeAll_102 = b.CreateOrder("EURUSD", OrderAction.BuyToCover, OrderType.Market, OrderEntry.Automated, TimeInForce.Gtc, [B]Position.Quantity[/B], 0, 0, "myOCO", "ProfitTarget", Core.Globals.MaxDate, null,);

b.Submit(new[] { closeAll_102 });

Does this look right?

Hello johnnybegoode,

This appears to be correct for sending an order to the Sim102 account for the quantity of the strategies position.

Is this sending an order when you are testing it?

Are you receiving errors?

[johnnybegoode]

I got errors (attached screenshot)

closeAll_102 = b.CreateOrder("EURUSD", OrderAction.BuyToCover, OrderType.Market, OrderEntry.Automated, TimeInForce.Gtc, Position.Quantity, 0, 0, "myOCO", "ProfitTarget", Core.Globals.MaxDate, null,);

Hello johnnybegoode,

Ah the Instrument needs to be an instrument object not a string.

You can use Instrument.GetInstrument() to get an instrument by a string name.
https://ninjatrader.com/support/help...instrument.htm
https://ninjatrader.com/support/helpGuides/nt8/en-us/createorder.htm

[johnnybegoode]

Order closeAll_102 = null;
Instrument myInstrument = Instrument.GetInstrument("EURUSD");
closeAll_102 = b.CreateOrder(myInstrument, OrderAction.BuyToCover, OrderType.Market, OrderEntry.Automated, TimeInForce.Gtc, Position.Quantity, 0, 0, "myOCO", "ProfitTarget", Core.Globals.MaxDate, null);
b.Submit(new[] { closeAll_102 });

It works only for one time.
Then I get an error - See Attachment

Hello johnnybegoode,

The message is correct. OCO IDs cannot be re-used once they have been used for an order that has been filled, cancelled, or rejected.

Reusing an OCO ID from a closed order is an attempt to pair a new order with an already closed order using OCO which is not possible.

You will need to use unique OCO strings.

Below is a link to an example.

And another thread where this is discussed.

https://ninjatrader.com/support/forum/forum/ninjatrader-7/platform-technical-support/91335-pending-orders-frozen?p=759355#post759355

You can write your own logic to make OCO strings unique.
GetAtmStrategyUniqueId() and System.Guid.NewGuid() can also be used to generate unique strings.

[johnnybegoode]

I added

string myOCO = GetAtmStrategyUniqueId();

Still getting the OCO resue message followed by the quantity error message under log.
It works for one time but then the strategy is disabled by the quantity error.

Hello johnnybegoode,

The error message is saying a quantity of 0 was used.

What line is causing the error?

What was the quantity supplied?

[johnnybegoode]

I think that was caused by the OCO reuse problem.
I'm still getting the problem message.

[NinjaTrader_ChelseaB]

Hello johnnybegoode,

If an order is rejected due to re-using OCO you will get a message that says:
"I am getting the error "Order XXXXXX can't be submitted: The OCO ID "XXXXXX" cannot be reused. Please use a new OCO ID. affected Order: BuyToCover XXXX Market"

May I confirm this is the error you are getting?

Do you want to address the other error you are getting about the order quantity?
