Unmanaged Order Methods

Unmanaged method is meant for users with advanced coding concept only. User with rudimentary coding concept or new user of ArthaChitra should prefer the Managed method.

If user wants to manage the orders by himself/herself, then he/she can do so by setting the IsUserManaged property to true when the strategy state is in Initialize state. The below code further demonstrates it

protected override void OnStateChange()
{
    switch (base.State)
    {
        case State.Initialize:
            base.IsUserManaged = true;
            break;

        //other codes
    }
}

Unmanaged Orders are meant for users with advanced coding concepts only as any rogue code (as written by user) may result in overfills, submission of multiple orders etc as the internal order handling rules are not followed here. For example the below code will submit a market order whenever the condition is fulfilled resulting in redundant orders/trades. A Managed Order on the other hand will ignore any redundant calls.

protected override void OnBarUpdate()
{
    if (Close[0] > 100.0d)
    {
        SubmitOrder("buy", OrderAction.Buy, OrderType.Market, 0.0d, 0.0d);
    }
}

To overcome the above scenario user can set a bool check to submit only once. The below code further demonstrates it.

bool isOrderSubmitted = false;

protected override void OnBarUpdate()
{
    if (this.State != State.Realtime) //Make sure to evaluate the orders when the state is in realtime only
        return;

        if (!isOrderSubmitted && Close[0] > 100.0d)
        {
            isOrderSubmitted = true; //making sure the order is not submitted twice
            SubmitOrder("buy", OrderAction.Buy, OrderType.Market, 0.0d, 0.0d);
        }
}
