UserDefinedMethods from NT7 to NT8

Hello stevenev1,

I also have an example you may find helpful.

After long search, this is the solution that finally worked for me. It shares method between indicators, but not between indicators and strategies (which I don't need). Putting code in AddOns directory is for me very complex and involves passing parameters such as Highs/Lows, etc. which I do not want to do.

Hello kiss987,

That would not be possible the way you currently have it since the Addon class would have no idea what instrument you are requesting TickSize for.

It would be possible by using BarsRequest similar to the samples on the forum post that I linked to.

Thank you for your reply.

I'm not sure I'm following your answer. I have the following code:

public double ReturnTickSize()
{
return (TickSize);
}

which I want to transfer it to my add on, so it will be available for both indicators and strategies:

namespace NinjaTrader.NinjaScript.AddOns
{
public partial class MySharedMethods : NinjaTrader.NinjaScript.AddOnBase
{
}
}

How is that possible?

Thank you

Hello kiss987,

You would need to add a bars request to access that information inside the addon class. Please see the following post that includes 2 samples on implementing a bars request.

Thank you for your reply,

Can I use objects such as TickSize, Highs, etc. from:

public partial class MySharedMethods : NinjaTrader.NinjaScript.AddOnBase
{
}

I wan only able to do so from within:

namespace NinjaTrader.NinjaScript.Indicators
{
public partial class Indicator
{

and:

namespace NinjaTrader.NinjaScript.Strategies
{
public partial class Strategy
{


However, I do not want to duplicate my code for strategies and indicators.

Hello kiss987,
Thanks for your post.

You will want to copy/paste the entire Indicator namespace into a .cs file placed in the Addons folder.

Please see the sample script at the following forum post that demonstrates.

Hello

I'm trying to transfer my code from NT7 to NT8.

On my indicator UserDefinedMethods file I used to have the following code:

namespace NinjaTrader.Indicator
{
    public class MyClass
    {
          // .....
    }
}

and

namespace NinjaTrader.Indicator
{
    partial class Indicator
    {
        public void MyFunction()
        {
              // .....
        }
    }
}

Where those 2 code parts should be transferred to on NT8?


Thanks
