How to set instrument in code...

[marketware]

I am new to Ninjatrader, but have written C# professionally for many years.

Can someone tell me how to set the instrument in code? I'd like to evaluate mulitple instruments without having to use the UI, and would most likely setup my code as a strategy.

Thanks!!

There are a few Sample Automated Strategies which come pre-configured in NinjaTrader that you can use as a starting point. These are found under Tools--> Edit NinjaScript--> Strategy. You will see locked strategies where you can see the details of the code, but you will not be able to edit (you can though always create copies you can later edit via right click > Save as)

We also have some Reference samples online as well as ‘Tips and Tricks’ for both indicators and strategies:

These samples can be downloaded, installed and modified from NinjaTrader and hopefully serve as a good base for your custom works.

We have a fully documented help guide which will help you get started with Ninja Script. You will find language references to all of the methods and functions you will be using. You will also see a tutorial section which will help you create your first indicator and get you started with some of these concepts.

A link to our Help Guide can be found below: http://www.ninjatrader.com/support/h...stribution.htm

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

There is a also a growing library of user submitted custom indicators (100+) that can be downloaded from our support form. Please look in the NinjaScript File Sharing section of our support forum as you may find what you are looking for there.

If you have limited time or programming capabilities, you can discuss your requirements with any of our certified NinjaScript consultants.

RE: How to set an instrument in Code

Thank you for your generic guidance. But I was wondering if someone could answer my question?

It seems on the surface that you have to determine the instrument in advance as part of the UI before you run a strategy against that instrument, and then you can have access to the Bars, (High, Low, Close, etc.) of that instrument. I'm looking for a way to setup an instrument without using your UI, but then use all of the classes, etc. that are available.

I see how you can use the Initialize method to add other instruments: (see below)

Add(Instrument, PeriodType.Minute, 5);

So I guess I am wondering if you can use "Add()" in other places in the strategy (not just the Initialize method). And if so, is there a "Remove()" method (I don't see one in the Docs).

Thank You!!

I apologize I must have miss-read your post the first time around. When you're creating a strategy it will be run from a chart or the strategies tab. This determines the primary instrument for the strategy. If you need to reference data from another series you can do so by adding them in Initialize()

The opposite "Remove()" does not exist in this context and Add() is only used in Initialize()

If you're wanting to work with multiple instruments/time frames within one strategy you will want to read the following section: http://www.ninjatrader.com/support/h...nstruments.htm

This will further explain how to reference different series. The primary instrument will always be set via the UI. If you needed to you could ignore the primary series in your code and force it to use the secondary/tertiary as needed.
