Indicator with SMA

[Turtle Trader]

I want to make an indicator something like the Ninja MACrossBuilder indicator...but with 4 different moving averages (instead of 2) plotting.

I don't need to have the period, et cetera, selectable in the parameters...they would be fixed in the code as they don't change.

Any examples to look at?

Turtle Trader, I think you can take the template from Ryan here - http://www.ninjatrader.com/support/f...h=cross&desc=1

and then just dont expose the parameters as public properties, but instead hardcode their values into the method calls.

Of course you then also need to add extra plots as per your needs.

hi Bertrand,

That link does not go anywhere, can you repost it?

Thank you.

The link goes to our sharing, which contains an MA cross builder shared by our RyanM, this could be a template for your works - http://www.ninjatrader.com/support/f...catid=4&id=426

Hi Bertrand,

I clicked again and the link worked...search results. thank you.

Though, I'm a newbie a Ninja coder....can you give me an example of how to assign attributes, like Period, MA Type, et cetera, to a Plot in the code? And assign a DataSeries to a Plot?

I've read the MA Cross Builder and don't see where those are being applied...they are in the parameters but not assigned to the DataSeries in the code..?

And, how is a DataSeries applied to a Plot?

Is there a class I can take to know these things?

Thank you.

If you're new to coding in NinjaScript, best would be checking through those tutorials for indicator coding we have prepared - http://www.ninjatrader.com/support/h.../tutorials.htm

Those would cover the basics needed for custom work and modifications.

The MA Builder code shared uses so called user defined inputs to set paramters - a tip in the education section explains those further - http://www.ninjatrader.com/support/f...ead.php?t=5782

If you just want to hardcode a period in, then assign the parameter in your MA method call for example - double mySMA = SMA(Close, 10)[0]; >> here the period is hardcoded to 10, there be no exposed user input dictating what is used, it will always be the coded in 10.
