How do I enter the following trading strategies?

[silver211]

Hello.　I am a beginner and don't really know how to use NinjaTrader.

The trading rules are these:

• Calculate the 15-day average of the daily High minus the Low (daily prices).
• Today is Monday or Wednesday.
• The close today must be lower than yesterday’s close minus the range in number one.
• We sell at the close of the third trading day.

Hello silver211,

Thanks for your post.

You could consider adding an additional Daily data series to your script using the AddDataSeries() method. Then you could access the High and Low prices of that added Daily series by using Highs[1][0] and Lows[1][0] to do your calculations. Highs[1][0] would get the current High price of the added Daily bar series. Highs[1][1] would get the previous bar's High price of the added Daily bar series. Highs[1][2] would get the High price 2 bars ago on the added Daily series, and so on.

See this help guide page for information about accessing PriceSeries values like Highs, Lows, Closes: https://ninjatrader.com/support/help...riceseries.htm

You could use a Time comparison or Time Filter to limit your strategy to taking certain actions during a specified time period.

Information about creating Time comparison conditions and Time Filters could be found on the help guide documentation linked below.
Time comparisons: https://ninjatrader.com/support/help..._builder.htm#H owToCreateTimeComparisons
Time Filter: https://ninjatrader.com/support/help..._builder.htm#H owToCreateTimeFilters

You could then create a condition in your script that checks if the current Low price from the added Daily series (Lows[1][0]) is Less than yesterday's Daily Close (Closes[1][0]) and call your Entry order method.

A condition would need to be created to check if three trading days have passed since your Entry order was placed and you would call your Exit order method to exit the current position.

NinjaTrader utilizes the C# programming language for developing indicators and strategies.

The best way to begin learning NinjaScript is to use the Strategy Builder. With the Strategy Builder, you can set up conditions and variables and then see the generated code in the NinjaScript Editor by clicking the View Code button. Note that the Strategy Builder does have limitations on what may be set up, however, this would be the best way to first learn and practice creating strategies in NinjaTrader.

Here is a link to our publicly available training videos, 'Strategy Builder 301' and '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:

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.

Thank you for your help.
I don't know how to program, but can I create a strategy from the Strategy Builder's Conditions and Actions?

Hello silver211,

Thanks for your note.

Some of the strategy could be set up in the Strategy Builder but you would need to unlock the script and manually program the strategy to detect if three trading days have passed since your last entry order was placed.

You can also contact a professional NinjaScript Consultant who would be eager to create or modify this script at your request or assist you with your script. The NinjaTrader Ecosystem has affiliate contacts who provide educational as well as consulting services. If you would like our NinjaTrader Ecosystem team follow up with you with a list of affiliate consultants who would be happy to create this script or any others at your request please email vendorsupport[AT]ninjatrader.com.

Let me know if I may assist further.
