How could I use other variables in my function, without duplicating code?
(in one indicator file)

[NinjaTrader_Jesse]

Hello,

Are you asking how to use a variable in the entire script?

If so you would need to define the variable outside of the methods body.

Here are a couple of basic examples:

protected override void OnBarUpdate()
{
     double lastPrice = 0;
}

This variable is defined inside of OnBarUpdate so it can only be used inside of OnBarUpdate.

private double lastPrice = 0;
protected override void OnBarUpdate()
{
      Print(lastPrice);
}
protected override void OnMarketData(MarketDataEventArgs e)
{
     Print(lastPrice);
}

This variable is defined outside of the OnBarUpdate so it can be used in OnBarUpdate or any other method that is in the same scope as OnBarUpdate

Please let me know if I may be of additional assistance.

How to create my method inside the indicator

[NinjaTrader_Jesse]

Hello,

Thank you for the question.

I will provide a simple example of this below, I would recommend reading some online tutorials on general C# syntax and logic, this will greatly help in understanding NinjaScript as NinjaScript is C#.

For methods in NinjaTrader,

Starting off in a indicator you will see the following lines near the top:

namespace NinjaTrader.Indicator
{
    [Description("Enter the description of your new custom indicator here")]
    public class Test : Indicator
    {

All of your code will need to go in between the open bracket { of the public class and its closing bracket }

To create a custom method you would need to define the method inside the class or:

namespace NinjaTrader.Indicator
{
    [Description("Enter the description of your new custom indicator here")]
    public class Test : Indicator
    {
         private void TestMethod(string valueOfPrint)
         {
              Print(valueOfPrint);
         }

         protected override void OnBarUpdate()
         {
               TestMethod("Hello");
         }
     }
}

Please let me know if I may be of additional assistance.
