Add horizontal lines to indicator in strategy script

[NinjaTrader_CalH]

Alexstox,

Yes, you can do that in the Initialize method, however, please note that the initialize method only gets called when you add the script to a chart. You would need to remove and add the script back from the dialog window.

When I tried to call for MyIndicator() in strategy, this caused an error because strategy required MyIndicator(1var, 2var, 3var). That's why I asked about how to call MyIndicator as default just MyIndicator()?

[NinjaTrader_CalH]

Alexstox,

Correct, when you add another indicator to a strategy or any other script, it will create a new instance of that indicator in which you will need to pass through values for the indicator.

You can create variables that will be the default to pass through the MyIndicator()

Can be these variables from MyIndicator? Not to set them in script? And how to implement this in strategy, where I call this indicator?

Alexstox,

You will need to pass values through values for the MyIndicator() in order for the instance to know what values to create it and calculate the indicator.

Alexstox,

You will need to pass values through values for the MyIndicator() in order for the instance to know what values to create it and calculate the indicator.

So, if there are var1, var2, var3 in MyIndicator, these variables should be in strategy script in Variables region and in MyIndicator(var1, var2, var3)?!

Alexstox,

No, that is not what I'm saying.

Let's try a different look.

When you add, say, an SMA() to the strategy you need to pass a value through the () in order for the SMA to know what to calculate with.

I.E. SMA(12)

However, you can create a variable that you can pass through the SMA instead so that you have more control over it rather than having to open the script back and forth to adjust the value.

Alexstox,

However, you can create a variable that you can pass through the SMA ...

I knew that, thanks
I thought default variables could be used without passing through () in indicator

1) So, how to script this

if([B][U]instrument==MSFT[/U][/B]) do something

2) If I change the instrument (MSFT to MMM) in the chart, will this reload Initialize() method and will Initialize() see the change of instrument?

3) how to script

If([B][U]instrument==futures or stocks[/U][/B]) do smth

[NinjaTrader_CalH]

Alexstox,

This does not reload the initialize() method as this is only called when the indicator is first applied to the chart.

You would need to do this in OnStartUp() method -

how to write this in script
if(instrument==MSFT)

[koganam]

I will check this. Thanks.
May I use IF() in Initialize()? For example, to filter ADD() only for some instruments?

if(instrument==MSFT) do something

And how to check what instrument now is using in strategy or indicator?

2) When I tried to call for MyIndicator() in strategy, this caused an error because strategy required MyIndicator(1var, 2var, 3var). That's why I asked about how to call MyIndicator as default just MyIndicator()?

There is no default constructor: you must use the full calling signature. That is, all inputs that are exposed as a GridCategory or listed as a Category("Parameters"), must be included on the calling line.

calling line is Indicator(1,2,3)?
What is GridCategory?

[koganam]

Look inside the code for your indicator. If the indicator has parameters, you must have exposed them as properties. Show an example of how you specified the Properties.

[alexstox]

Yes! I got it!
So, if I want to add MyIndicator() without anything inside (), I should not declare indicator variables in

#region Properties
[Description("......")]
        [GridCategory(".......")]

I'm feeling like script guru
thank you guys!!!
