Indicator button to modify ATM Target

[thepcmd]

I currently have an indicator that can modify Stop1 order to BE of an ATM that has been placed on the Chart. I am trying to get another button to Modify the Target1 order to BE +1 is this possible, I have pasted the button 'code' below

protected void myTargetBE(object sender, RoutedEventArgs e)
{
Account Acct = Account.All.FirstOrDefault(x => x.Name == xAlselector.SelectedAccount.ToString());
Position thisPosition=Acct.Positions.FirstOrDefault(x => x.Instrument.FullName==Instrument.FullName) ;
NinjaTrader.Cbi.Order myOrderToChange = null;
foreach (Order order in Acct.Orders)
{
if(order.OrderType==OrderType.Limit || order.OrderType==OrderType.MIT)

if(order.OrderState != OrderState.Cancelled & order.OrderState != OrderState.Filled)
{
if (order.Name=="Target1")
{
myOrderToChange.LimitPriceChanged = thisPosition.AveragePrice+ 1 * TickSize; // adjust to +1 ticks above entry price
Acct.Change(new [] { myOrderToChange });
}
}


}
}

Hello thepcmd,

Yes, it would be possible to change the price of an order from a button click handler method.

This is from a manually submitted entry that has an Atm Strategy attached?
As a heads up, the Atm Strategy would continue running and would likely undo any price changes you make as it continues operating.

Is there an issue or error you having you want assistance with?

Whenever I use the code above I get the following 'Unhandled exception: Object reference not set to an instance of the object.' That is what I am having issue with.

Hello thepcmd,

The error is stating that a variable you are using has a null value.

You can add prints above each line and look to see what the last print to appear is. The line of code below is likely the line causing the error.

You can test each variable and check to see if it is null.

For example:

private Order myOrderToChange;

if (myOrderToChange == null)
{
Print("myOrderToChange is null");
}

If you are not finding the order in the account Orders collection, print each order in the collection.
Print(order.ToString());

Below is a link to a forum post that demonstrates how to use prints to understand behavior.

What variable has a null value?
