Unmanaged orders

[hanysfx]

Hi, i have problem with unmanaged orders. If I start strategy at first time and open orders like this:
Order2 = SubmitOrder(0 , OrderAction.Buy, OrderType.Stop, LotSize, 0, Price1var, "Long", "Enterlong");
Order1 = SubmitOrder(0 , OrderAction.Sell, OrderType.Stop, LotSize, 0, Price2var, "Short", "Entershort");

that work right. But If i close strategy and run it again, orders are sent to broker and immediately are canceled with this error:
Order rejected - reason: The OCA group order has alreadt been filled. (201).

But there are no opened order, could you help me please? Thank you

Hello hanysfx,

This may be expected depending on what broker provider you use as you are submitting the orders again with the same OCO Id. You may want to generate a unique OCO Id each time like "GetAtmStrategyUniqueId()" or your own method.

Let us know if that helps.

My broker is Interactive Brokers.
I changed code to this:
string orderId1 = GetAtmStrategyUniqueId();
string orderId2 = GetAtmStrategyUniqueId();

Order2 = SubmitOrder(0 , OrderAction.Buy, OrderType.Stop, LotSize, 0, Price1val, "Long", orderId1);
Order1 = SubmitOrder(0 , OrderAction.Sell, OrderType.Stop, LotSize, 0, Price2val, "Short", orderId2);

and there is same error.

Hello hanysfx,

The "OCO Id" is going to be the second one from the last, not the last one.

Order1 = SubmitOrder(0 , OrderAction.Sell, OrderType.Stop, LotSize, 0, Price2val, "Short", [B]orderId2[/B]);

SubmitOrder(int barsInProgressIndex, OrderAction orderAction, OrderType orderType, int quantity, double limitPrice, double stopPrice, [B]string ocoId[/B], string signalName)

You may want to switch them around.
