how to test when ATM is "None" ?

[llanqui]

when the ATM is set to None....how can I tell this in Ninjascript?

[llanqui]

in NT7 I could test for the string "<None>"

but there is no string available in NT8 and there is no object to test ...

Hello llanqui,

If you are referring to the Chart Trader Atm selector, you can check that the ChartControl.OwnerChart.ChartTrader.AtmStrategy.Te mplate is null.

[llanqui]

ok, will try that thanks

[llanqui]

I'm getting an error

Object Reference not set to an instance

if (ChartControl.OwnerChart.ChartTrader.AtmStrategy.T emplate == null)

Hello llanqui,

May I confirm this strategy is added to a chart and this line of code is in OnBarUpdate()?

Is the ChartControl null?

[llanqui]

no, it is in button click event in an indicator

these have no problem

this_Account = ChartControl.OwnerChart.ChartTrader.Account;
this_AccountName = ChartControl.OwnerChart.ChartTrader.Account.Name;
this_Quantity = ChartControl.OwnerChart.ChartTrader.Quantity;

[llanqui]

looked at your code agaon..

well, I'm not using ChartControl.Dispatcher.InvokeAsync

it works ok, except for when I want to access the ATMStrategy....

will do more testing

Ok, I imported the indicator SubmitChartTraderATM from here

https://forum.ninjatrader.com/forum/ninjatrader-8/indicator-development/1132389-having-an-issue-extracting-atm-strategy-name-from-chart-trader#post1132405

questions:

1) If the ATM is NONE the code does not submit an Order...but I don't see how this is filtered out?

2) If I change the ATM while it is running, it gets an error

Error on triggering custom event for NinjaScript 'XXTestATM' on bar 3601: There is an error in XML document (0, 0).

I noticed that while I was testing my own .... can you tell me what the problem is?

Many thanks

[llanqui]

Ok, to answer Forum above....the ATM definition apparently was corrupt....so, not a problem

But still I need to solve question 1 in the prior msg...that was my original question...

Hello llanqui,

I see the issue, the AtmStrategy object is null (and not just the template).

ChartControl.Dispatcher.InvokeAsync(() =>
{​
    if (ChartControl.OwnerChart.ChartTrader.AtmStrategy == null)
    {
        Print("atmStrategySelector is set to <none>");
    }
    else
    {
        Print(ChartControl.OwnerChart.ChartTrader.AtmStrategy.Template);
    }
});

[llanqui]

Ok, that should work...will test it...thank you...

By the way, it would be extremely helpful if there was a dictionary of all the internal objects and the hierarchy of how they are related...

like a Tree List Dictionary

Does anything like that exist?

Hello llanqui,

There is not an intention to make the chart trader controls available to NinjaScript. These are not documented and are being supplied by the support team as we discover these objects and properties can be manipulated.

This also includes getting things by AutomationID. You can use MSInspect as we do to find the object type and automation id of things.

ok, that is a little beyond my skill set at the moment, but I can always study Automation ID and Inspect

in NT7 there was a lot of activity on Futures IO that documented things like this
