ORB strategy

[NinjaTrader_Emily]

Hello caspian,

Thank you for your reply.

First, I see you have created this as a strategy script. As previously mentioned, this would need to be done with an indicator that calls AddPlot():

https://ninjatrader.com/support/helpGuides/nt8/addplot.htm

The indicator would then be available to add to the Market Analyzer as an indicator column:

https://ninjatrader.com/support/helpGuides/nt8/working_with_columns.htm

I also see you are trying to access high and low prices in OnStateChange during State.DataLoaded:

else if (State == State.DataLoaded)
{
// Calculate IB range from 09:15 am to 10:15 am
ibHigh = Highs[1][1];
ibLow = Lows[1][1];
}

This is not possible and I would expect it to cause errors. Although data has been loaded at that point, it is not being processed yet so having a barsAgo reference does not make any sense until STate.Historical and State.Realtime. For more information, please see the OnStateChange() page here:

https://ninjatrader.com/support/helpGuides/nt8/onstatechange.htm

Thank you for your time and patience.

From our experience at this time, ChatGpt is not quite adequate to generate valid compilable NinjaScripts that function as the user has intended. We often find that the generated code will call non-existent properties and methods, use improper classes or inheritance, and may have incorrect logic. We highly encourage that you create a new NinjaScript yourself using the NinjaScript Editor, and use the code generated by ChatGpt as more as suggestions and guide when coding the script yourself, than using the actual code generated.

While it is not within our support model to correct these scripts at user request, we would be happy to provide insight for any direct, specific inquiries you may have if you would like to create this script yourself. As I have mentioned, our support is able to assist with finding resources in our help guide as well as simple examples, and we are happy to assist with guiding you through the debugging process to assist you with understanding unexpected behavior.

This thread is open to other forum users who would like to correct this script for you, or 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. Please let me know if you would like a list of affiliate consultants who would be happy to create this script or any others at your request or provide one-on-one educational services.

Thank you for your patience and understanding.

Hello caspian,

As I previously mentioned, ChatGpt is not quite adequate to generate valid compilable NinjaScripts that function as the user has intended. We often find that the generated code will call non-existent properties and methods, use improper classes or inheritance, and may have incorrect logic. We highly encourage that you create a new NinjaScript yourself using the NinjaScript Editor, and use the code generated by ChatGpt as more as suggestions and guide when coding the script yourself, than using the actual code generated. For example, the snippet you have posted uses both the indicators and strategies namespaces:
namespace NinjaTrader.NinjaScript.Indicators
namespace NinjaTrader.NinjaScript.Strategies

This would not be valid for NinjaScript to generate the necessary code. Please use the NinjaScript Editor to open a new indicator or strategy via the wizard and post in the necessary code. For more information on using the NinjaScript Wizard:

Please let us know if we may be of further assistance.

HI EMILY. https://ninjatrader.com/support/help...?ns_wizard.htm THE INDICATOR GET HIGHLOW BY TIME RANGE. CAN YOU CREATE A VIDEO BY ADDING ADDITIONAL CODES. SUCH AS IF THE CLOSE CROSSES ABOVE THE HIGH OF THE RANGE SIMILARLY IF THE CLOSE PRICE CROSSES BELOW THE LOW OF THE RANGE LOW. IT SHOULD SHOW INITIAL BALANCE RANGE BREAK HIGH OR IB LOW BREAK. PLEASE PLEASE PLEASE EMILY.

Unfortunately, in the support department at NinjaTrader it is against our policy to create, debug, or modify, code or logic for our clients. Further, we do not provide C# programming education services or one-on-one educational support in our NinjaScript Support department. This is so that we can maintain a high level of service for all of our clients as well as our associates.

That said, through email or on the forum we are happy to answer any questions you may have about NinjaScript if you decide to code this yourself. We are also happy to assist with finding resources in our help guide as well as simple examples, and we are happy to assist with guiding you through the debugging process to assist you with understanding unexpected behavior. Further, debugging code created by AI tools such as ChatGPT typically goes beyond the boundaries of what our support team offers.
