Problem with account Leeloo

[jodu49]

Hello,

I have a problem with my code which works very well on Sim account. It bug with an LL account (Leeloo connected to Ritmic)
I get an error message : Unhandled exception



After research, the following instruction is the problem: Acct.Positions.Count

Thanks for your help.




My code is :
protected void Button1Click(object sender, RoutedEventArgs e)
{

xAlselector = Window.GetWindow(ChartControl.Parent).FindFirst("C hartTraderControlAccountSelector") as NinjaTrader.Gui.Tools.AccountSelector;
quantitySelector = Window.GetWindow(ChartControl.Parent).FindFirst("C hartTraderControlQuantitySelector") as NinjaTrader.Gui.Tools.QuantityUpDown;

Account Acct = Account.All.FirstOrDefault(x => x.Name == xAlselector.SelectedAccount.ToString());


if (Acct.Positions.Count>=0) { OpenBuy(quantitySelector.Value); /*for (int n=1; n<=quantitySelector.Value; n++) AddStopLoss(1);*/ return;}
else {DisplayInfo("Not Possible because Position Already Open !!!",Brushes.Red); return;}
}

Hello jodu49,

The line below is redundant:
Account Acct = Account.All.FirstOrDefault(x => x.Name == xAlselector.SelectedAccount.ToString());

You could use:
private Account Acct;

Acct = xAlselector.SelectedAccount;

You will need to check that xAlselector are Acct are not null.

if (xAlselector != null)
{
Acct = xAlselector.SelectedAccount;
}

if (Acct != null)
{
if (Acct.Positions.Count>=0)
{
}
}
