Tick Counter With Output

[minipax]

Hello. What I would like is for the native tick counter to output a signal to be used by blackbird. This signal will occur when tick counter is less than x ticks. This is my first time writing a script. I started with the NT indicator wizard and added elements from the sample bool series.

I've read a couple forums on how to write this, and ended up here: https://ninjatrader.com/support/foru...t-plots?t=4991

This is for NT8: When I compile it, I get the following error: tickentry already contains a definition for "entryindication" Thank you for your help. I dont know how to place the code in a zipfile so I just pasted it here. sorry for the inconvenience.

//This namespace holds Indicators in this folder and is required. Do not change it.
namespace NinjaTrader.NinjaScript.Indicators
{
public class TickEntry : Indicator
{
private Series<bool> EntryIndication;
private double exposedVariable;

if (State == State.SetDefaults)

Description = @"Will generate a signal for Blackbird to place a trade when current bar's tick count is less than x ticks";

Hello minipax,

Thanks for your post.

In your script, you have a private variable called EntryIndication and a public variable called EntryIndication. Since these variables have the same name, you would need to modify one of the variables so that the name is different.

AddPlot() would be used to add a plot to your script to act as a 'signal' when a certain condition occurs. That plot could then be referenced using the Strategy Builder or Blackbird if that is supported by Blackbird.

I highly suggest reviewing the Indicator development tutorials in our help guide to get a solid understanding of how to develop indicators. I am linking the Indicator tutorials below.

Indicator Tutorials: https://ninjatrader.com/support/help...indicators.htm

Also, see this help guide page about using AddPlot(): https://ninjatrader.com/support/help...t8/addplot.htm

If you encounter any compile errors while building your script, debugging steps would need to be taken to determine what exactly in the script is causing the error to occur.

Below is a link to a forum post that demonstrates how to use prints to understand behavior.

https://ninjatrader.com/support/foru...t-plots?t=4991 was the one I needed to create this type of indicator. It has both private and and public variables with the same name. I did notice that the post was from 2008, so I dont know if that post is still valid.

Hello minipax,

Thanks for your note.

We have a SampleBoolSeries reference script located in the NinjaTrader Help Guide which uses public and private variables. See the SampleBoolSeries reference sample linked below.
