Hi I would like to set a limit order within my study.
I use
s_SCNewOrder NewOrder;
NewOrder.OrderQuantity = 1;
NewOrder.OrderType = SCT_ORDERTYPE_LIMIT;

this Limit I need to change regarding the situation on market, In my understanding this is set at once, But I need to change it if the situation change
do I have to use modifyorder or it will change automaticly?
regards

You would have to call sc.ModifyOrder, pass sc_SCNewOrder structure and fill InternalOrderID same order you need to modify.
