Please teach me how to program about the following two things

[silver211]

Hi, I am a newbie ninja trader.

I am posting this because I wanted to ask how to program the following two things.

1. buy at today's close and sell at tomorrow's close

2. buy at today's close and sell at a higher close than the value you bought during the next 5 days. If not, sell at the closing price of the 5th day.

Hello silver211,

Thanks for your post.

Something you could consider is creating a time comparison condition to check if the Time is the end time of the session, check if you are in a Flat market position (Posiition.MarketPosition == MarketPosition.Flat), and then submit your order by calling your Entry order method, such as EnterLongLimit()/EnterShortLimit(), to submit an order to the Close price of that candle.

You could then check if the Time is a certain time, check if you are in a Long or Short Market position, and call your Exit order to exit the position once the Time reaches the specified time again on the next day.

A Day comparison could also be added to your conditions to see if the current Day is a specific day of the week.

A double variable could be created and you could save the Close price to the variable when you submit your Entry order. You could then compare if the current Close price is greater than that variable when the Time is a specific time.

Ultimately, it would be up to you to come up with the specific logic to accomplish the specific strategy you want to create.

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.

Here is a link to our publicly available training videos 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:

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

Dear customer survice,

Thank you for reply..

I am currently using strategy builder.

If i buy at today's closing price and sell at tomorrow's closing price

Is it correct to execute the "Entrylong" instruction at close(1) and the "Exitlong" instruction at close(0)?

close(1) is the previous day's high, right?

Hello silver211,

Thanks for your note.

Close[1] will refer to the previous bar's close price. Close[0] will refer to the current bar's close price. If you are using 1-Minute bars, Close[1] would refer to the previous minute bar's close price and Close[0] would refer to the current bar's close price.

You could use the Prior Day OHLC indicator (Indicators folder > Prior Day OHLC > 'Value plot' parameter > 'Prior High') to get the prior day's High price in a strategy condition.

Note that EnterLong() will submit a market order to the current market price.

I suggest watching the Strategy Builder 301 video linked in post # 2 and working through the tutorials on the Educational Resources help guide page linked in post # 2 below to gain a good understanding of working with the Strategy Builder before trying to create your strategy.

Please let me know if I may assist further.

Dear, customer service

I would like to watch the Strategy Builder 301 video, but the link is broken and I cannot see it. The video seems to be private.

Could you please reiterate the correct link?
