HAMAVeroot Indicator Transfer from TD Ameri to NT8 HELP

[chasep7328]

Hello all,
I have a rather interesting indicator that I use to spot swing trades on TD Ameritrade and would like to have it transferred over to NT8 for visual use and also have it usable in a backtesting strategy for the system if possible. Attached is a picture of what it looks like and the code for it. I like to buy once the price closes above the blue line and create a stop once the price closes back below the blue line in up trends (vice versa for the purple line at the bottom for shorts). I also like to have the ability to just trade once the color of the current bar changes to either green/red and trade in that given direction, put a stop at the high/low from the previous bar before the color change, or simply exit the trade once the current bar turns grey again. I don't have much coding experience to transfer it over but does anyone else know where to start? Thanks.

Hello chasep7328,

Thanks for your post.

The C# programming language is used for developing NinjaScript indicators and strategies.

To create a NinjaScript indicator, open a New > NinjaScript Editor window, select the '+' tab at the bottom of the Editor window, select 'New Indicator'. Then, you could set up as much of the indicator as possible in the Indicator Builder. This will create the framework of the indicator or strategy

Once you finish setting up as much as possible in the Indicator Builder, you must manually program the rest of the indicator.

When first starting to convert scripts, you should open the TD Ameritrade developer help guide and the NinjaTrader 8 help guide so that you could compare methods and properties between the two platforms. The majority of code supported by NinjaTrader is included in the help guides.

Below is a link to a forum post with helpful information about getting started with NinjaScript.
https://ninjatrader.com/support/foru...040#post786040

Here is a link to our publicly available training video, 'NinjaScript Editor 401', for you to view at your own convenience.

I am also linking you to the Educational Resources section of the Help Guide to help you get started with NinjaScript:
https://ninjatrader.com/support/help..._resources.htm

If you are new to C#, to get a basic foundation for the concepts and syntax used in NinjaScript I would recommend this section of articles in our help guide first:
https://ninjatrader.com/support/help...g_concepts.htm

And the MSDN (Microsft Developers Network) C# Language Reference.
