Using ForceRefresh in NS

[ToMer_K]

Hi,
The ForceRefresh() method is not accessible from any function in ninjascript. How can I use it? Any way to refresh asynchronously like I saw people use in NT7 (Cbi.Globals.SynchronizeInvoke.AsyncInvoke)?

Hello ToMer_K,

Thank you for your post.

You can find details on ForceRefresh() at the following link: http://ninjatrader.com/support/helpG...rcerefresh.htm

You can use Dispatcher.InvokeAsync in NinjaTrader 8. Please visit the following link for more details: https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx

This is where I encountered the ForceRefresh() method. I can see it is accessible by indicators and not strategies. Anyway to make it available for my strategy?

Will using it asynchronously can cause issues?

Hello ToMer_K,

Thank you for your response.

You could use a dispatcher in the Strategy. ForceRefresh() is used for objects that use OnRender() where a strategy would not call OnRender() in most cases.

Hi,
I guess you do not follow me correctly. There is no method called "ForceRefresh" when inheriting from Strategy. How can I still use it in a strategy?

I see it comes from IndicatorRenderBase. Anyway to access it without instantiating an Indicator?

Hello ToMer_K,

You can instantiate an indicator and then call ForceRefresh from the indicator. For example:

private SMA mySMA;
...
			else if (State == State.Configure)
			{
				mySMA = SMA(20);
			}
...
		protected override void OnBarUpdate()
		{
			mySMA.ForceRefresh();

Anyway to access it without instantiating an Indicator?

I have no indicator in my strategy and I think it is a waste to instantiate an indicator just for using the refresh function... It takes more resources and adds redundant event calls. I need my strategy to run as fast as possible.

If there is no way to do so I recommend you to add this function to strategies as well because many of them use visualizations here and there that may need faster refresh.

I will submit your suggestion to development.
