I would like to get a breakout strategy ninjascript written for ninja trader. I have no experience doing this and need help writing and understanding the script. I would like the ninjascript strategy to center on current market price set buy long at +10 points with an attached OCO set a sell short at -10 with an attached OCO if buy or sell triggers then the other cancels upon order fill a trailing stop is set at 10 points. Any help would be greatly appreciated.

Thanks all

Hello dainghia,

Thanks for your post and welcome to the NinjaTrader forums.

For your understanding, in the support department at NinjaTrader we do not create, debug, or modify code for our clients. This is so that we can maintain a high level of service for all of our clients.

Ninjascript strategies can be created as two types, either managed or unmanaged. A managed strategy means that NinjaTrader will put controls in place to prevent unwanted positions and if anything goes wrong would act to close positions and shut the strategy down. As such the managed approach would be necessarily limited in what you can do. An unmanaged strategy would permit you to do basically anything however you as the programmer would have to take responsibility for all actions and code for all conditions to handle all situations. The strategy you have described would best be done in the unmanaged approach, however, due to the complexity, it would be quite challenging to script. Here is a link to the managed approach and unmanaged approach that provides an overview:

A recommendation here would be to work with a 3rd party programmer who is proficient in Ninjascript strategies. If this is of interest please let us know and we can provide a link to various 3rd party programmers you could contact.

If you would like to take on learning NinjaScript, we have a fully documented help guide which will help you get started. 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. Please note that Ninjascript is based on C# programming language so it would use the same syntax rules as C#.

This video introducing the NinjaScript editor is an excellent resource,

You will find reference samples online as well as some 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.

There is also a growing library of user submitted custom indicators (100+) and strategies 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:

Finally, the following link is to our help guide with an alphabetical reference list to all supported methods, properties, and objects that are used in NinjaScript.

Futures, foreign currency and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

CFTC Rules 4.41 - Hypothetical or Simulated performance results have certain limitations, unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profit or losses similar to those shown.
