Detecting Shave Bars and One Tick Tails?

[timmbbo]

How do I detect:

- Shaved bars, with no tail on top or bottom
- Bars with a shaved top, and a one-tick tail on the bottom.

In both cases, the bar is shaved on the top side in the momentum of the trade. On the bottom side, it's either shaved or a one tick tail. I can't find the right property to unlock this bar attribute. Thanks.

Hello timmbbo,

Thanks for your post.

There is no bar attribute that matches your descriptions. To detect these conditions you would need to create an indicator.

The conditions could be coded something like:

if (Close[0] > Open[0] && Low[0] == Open[0] && Close[0] == High[0])
{
//shaved up bar, do something
}

else if (Close[0] > Open[0] && Low[0] == Open[0] - 1 * TickSize && Close[0] == High[0])
{
// Shaved top with 1 tick tail, do something
}
else if (...)

You would continue to code in that manner to detect the various conditions you are looking for.

Thanks for the example - I have it working now.

Hi timmbbo or PaulH I'm new to this forum and was reading over your request and wanted to know if you didn't mind sharing the file? I'm a total newbie at coding and I'm not sure how to add in the information provided. Thanks in advance

Hello JustinaM,

Thanks for your post and welcome to the NinjaTrader forums!

I do not have the file to share.

The code I showed would go into the OnBarUpdate() method, however, all I showed was how to configure the condition as I did not know what actions member timmbbo wanted to perform.

NinjaScripts are built on C#. While we do not provide programming education services in the Support Department, there are a vast number of educational C# resources external to NinjaTrader and we do have some tutorials and tools that can assist in the learning process.

Many users report that a good way to start before fully learning C# is to go through the NinjaTrader 7 NinjaScript tutorials in the help documentation to get a fundamental grasp on .NET framework and how it is used in NinjaScript. From there I suggest looking at the Code Breaking changes for NinjaTrader 8 to understand the differences between NinjaTrader 7 and NinjaTrader 8.

You can view the tutorials for NinjaTrader 7 here: https://ninjatrader.com/support/help...?tutorials.htm

Although we do not currently provide NinjaScript tutorials like in NinjaTrader 7, we do provide in-depth help documentation on developing NinjaScripts for NinjaTrader 8. We also provide samples and a complete reference of the language. More in depth educational resources can be found elsewhere throughout the internet.

You can find the educational resources here: http://ninjatrader.com/support/helpG..._resources.htm

Once you have a basic understanding of C#, I suggest following the documented Code Breaking changes between NinjaTrader 7 and NinjaTrader 8. This page also gives an overview for NinjaScripts in NinjaTrader 8.

You can find the Code Breaking changes here: http://ninjatrader.com/support/helpG...ng_changes.htm

Also available are webinars on the NinjaScript editor and the Strategy Builder. The Strategy Builder can be used to generate NinjaScript syntax for NinjaScript strategies. You may wish to create a strategy and clicking View Code after each piece of logic created in the Builder to observe the generated syntax.

The information above is publicly available.

Finally, we also have a vast EcoSystem of NinjaScript Consultants that would be happy to write or modify any NinjaScript at your request. If those services interest you, we can have a representative of our EcoSystem reach out with more information.

Thank you so much for all the information! I appreciate it!

Good Morning PaulH, I tried making the indicator and I wasn't able to get the signal onto the chart but it will compile with no errors, can I send over an email and have you take a look? Also, I would like to have the Consultants contact me. Thanks

[NinjaTrader_PaulH]

Hello JustinaM,

Thanks for your reply.

While a script can compile without errors the compiler cannot test run-time conditions. When you apply the indicator to a chart, please check the "Log" tab of the NinjaTrader control center for any related error messages. Do you see any errors?

I will ask our vendor support team to post a message here for you.

Good morning PaulH I checked the Log and there are no related errors being shown. I was under the impression that you all actually do coding services yourselves. But I took a look at the list and thank you.
