Subscribing another class to BarUpdates

[reach4thelasers]

Hey there.

I've got a dependent class which needs to know about BarUpdate events.

I found the _ninjaScriptBase.Bars.BarUpdate event

and have subscribed to this event. The event fires for realtime updates but not during historical data processing.

How can I get these updates for historical data too? I want this event to fire any time the indicators OnBarUpdate event is called; which includes historical data.

I've attached a small indicator to demonstrate what I'm trying to do.

Thanks

Kevin.

Hello Kevin,

Thank you for your post.

Why not just call the function in OnBarUpdate()?

To grab historical bars you use BarsRequest: http://ninjatrader.com/support/helpG...arsrequest.htm

Please let me know if you have any questions.

Hello Kevin,

Why not just call the function in OnBarUpdate()?

In my job as Lead Solution Architect in a Financial Software house I've got a reputation for yelling "S.R.P" to my developers. Its the first principle of SOLID design and stands for Single Responsibility Principle. I'd rather not have everything lumped into the OnBarUpdate method, so as to practice what I preach: If they checked-in a class that had over 500 lines or methods that have over 50 lines I would reject it as an SRP violation and ask them to refactor it. To be honest I think lately they've started deliberately provoking me to see who can get me to say it first.

Anyway.... I have many instances of my class that needs to know about bar updates so I'd rather they managed their own concerns when this happens. I will figure something out.

thank you!
