hi guys i want try to see this example

Examples

protected override void OnMarketDepth(MarketDepthEventArgs e) { // Print some data to the Output window if (e.MarketDataType == MarketDataType.Ask && e.Operation == Operation.Update) Print("The most recent ask change is " + e.Price + " " + e.Volume); }

i have created this indicator

Hello faustf,

Thank you for the post.

What error are you seeing? Was this a compile error or when you ran it?

I see that the code can compile and I ran it but see no errors. Could you explain in more detail what the problem you are having is?

As a side note, for future attachments you can attach the .cs file for the script instead of pasting the entire contents, the file resides in the folder: Documents\NinjaTrader 7\bin\Custom\Indicator

I look forward to being of further assistance.

i have always this error
' does not contain a definition for 'MyInput0' and no extension method 'MyInput0' accepting a first argument of type 'NinjaTrader.I

Hello faustf,

In what you provided I don't see an error, I also see that this can compile on my end. I would suggest to try and attach the file directly in case something was left out, otherwise because the file is just being started you may want to delete this and create a new indicator. The MyInput is a generic input that is generated in a new indicator by default, that by default will compile if you don't change or remove the code associated with it. You can also use the indicator wizard when you create the indicator to remove the input if it is not needed.

I look forward to being of further assistance.
