Calling ninja trader functions outside OnBarUpdate

[martraf]

Hi,
do i get it right, that I can't do as simple thing as calling drawing and indicator functions in my own function? For example

class Sample2:Sample
{
 public override void Calculate(IDataSeries data) {
 double price=SMA(data,10);
 DrawDot(.....);
//so on
 }
}

I want to call Calculate from OnBarCalculate. If I can't do that, whats the point in using OOP with Ninja Script if after all I have to put everything in single function using old style "if else" (can't use polymorphism and so on). I've found simple workaround- to create singleton that would keep track of all drawing operations in a list and execute them at OnBarCalculate (then clear the list). I can also rewrite indicators as normal functions but this is so inelegant I simply can't believe its the only way and it's not already implemented.

Regards,
Rafal

Hello,

We do allow users to create and use their own classes. However this is not something we directly support.

The OOP allows us to create an indicator and strategy base class in which all of the custom indicators and strategies inherent from.

Through this we are able to make the creation of custom scripts and indicators much simpler by providing users with methods that perform various trade and drawing related tasks for them.

OnBarUpdate() is called every time a bar closes or a new tick of data comes in (depending on the COBC setting: http://www.ninjatrader.com/support/h...onbarclose.htm )

Let me know if I can further assist or clarify.
