errors in marketanalyser columns

[junkone]

I got these 2 errors that I don't understand. can you clarify? I have also attached my code

Time Category Message
5/13/2016 11:04:58 AM Default Market analyzer column 'MyStates': Error on calling 'OnMarketData' method on bar 49: Write lock may not be acquired with read lock held. This pattern is prone to deadlocks. Please ensure that read locks are released before taking a write lock. If an upgrade is necessary, use an upgrade lock in place of the read lock.

Hello junkone,

It looks like you are calling an indicator from a MarketAnalyzer column.
The issue here is that there is not a dataseries created that can be supplied to the indicator call.

You will need to make a BarsRequest and from the bars update method get the bars object and use that as the input series for the call to the indicator.

protected void CustomBarUpdate(object sender, BarsUpdateEventArgs e)
{
Bars theBars = sender as Bars;
Print(SMA(theBars, 14)[0]);
}

Attached is an example I have created previously that shows how to do a BarsRequest in a Market Analyzer column.

Does this script need to be a Market Analyzer column? From the code, it looks like this script only calls an indicator. This could remain an indicator and be added to the Market Analyzer as an indicator column.

[junkone]

I still get a internal error after fixing the code
you will notice that I created bar subscription and am calculating the values based on the subscribed bars.
when I print the values, I get error

Hi junkone,

I think Chelsea was suggesting to try and make an indicator instead of a MA column (if it is possible to achieve your objectives, or use the existing indicator you are calling), and then load the indicator as a 'column' into the MA. I also took that approach as I found this was better because you can use OnBarUpdate as opposed to OnMarketData and for me was more familiar.

For that error 'All data must first be loaded by the hosting NinjaScript in its configure state', try adding a bool which switches to true in State.DataLoaded and checking against that before running your other logic. This worked for me (I had an indicator loaded in the MA with multiple data series and I was getting that same error intermittently).

Cheers,
Shane

I think I am doing exactly as identified by Chelsea. I have a custom OnBarUpdate which processes the bars. infact I have checked if the state ==State.realtime which implies that all data is already loaded. it stops with the same error. I have a feeling that its a bug at this state. infact, I printed the barcount and it starts with 200 and when it moves to 201, something happens in the processing that causes this error.

Hi junkone,

As I am not able to test your script, I have created a simple script to show how to use a bars request and provide the bars object to an indicator call. I have exported this to make this easy for you to import and test on your end. (Tools -> Export -> NinjaScript...)

To import a NinjaScript into NinjaTrader 8 do the following:

1. Download the script to your desktop, keep it in the compressed .zip file.
2. From the Control Center window select Tools -> Import -> NinjaScript...
3. Click the Desktop icon on the left to navigate to the desktop
4. Select the downloaded .zip file -> then click Open
5. NinjaTrader will then confirm if the import has been successful.

Critical *Note that on any files that say "File already exists on your PC" that start with an "@" symbol are the ones that came preloaded inside of NinjaTrader so you would say "No" so that you do not override those files.

i don't see why you have to go through all that trouble to plot sma on market analyzer. the onbarupdate can be overridden and plotted much more simply. I think the problem with the cases that I had earlier was due to the fact that I am using tick and minute bars in my indicator and when I called it from market analyser, there is no ticks bars to process it. I cannot figure out why NT will throw the error and where it is throwing the error.
I am attaching a simplier code to prove that we don't need to create bars array to plot simple indicators in market analyser.

}

Finally, I still have a problem with the code posted yesterday and need to know how to fix it.

Hello junkone,

Thank you for the sample.

I clarified with our development that a bar object does get created with a Market Analyzer column.

Is the indicator being called adding a secondary data series?


As a tip, to export a NinjaTrader 8 NinjaScript do the following:

1. Click Tools -> Export -> NinjaScript...
2. Click the 'add' link -> check the box(es) for the script(s) you want to include
3. Click the 'Export' button
4. Enter a unique name for the file in the value for 'File name:'
5. Choose a save location -> click Save
6. Click OK to clear the export location message

By default your exported file will be in the following location:

• (My) Documents/NinjaTrader 8/bin/Custom/ExportNinjaScript/<export_file_name.zip>

Below is a link to the help guide on Exporting NinjaScripts.

I have the similar problem when I load a strategy. I will send my code and I can see that the error is logged in Ninjatrader code that I cannot touch.

Hello junkone,

This likely means that an error is being hit in the indicator and likely is not specific to the market analyzer.

If you are not able to post the script, this is likely because the script has a lot of code you would like to keep private.

Instead, create a simple example script that only includes the code to reproduce the behavior. By only including the code that causes the behavior this will allow me to quickly view the code and see the issue without having to debug your script which is not a service that is provided by NinjaTrader support.

Please create a sample that demonstrates the behavior and does not include any code that is not absolutely necessary to reproduce the behavior.

Also, you can use prints to find out which line is causing the error. Have you added any prints to your code to debug the code?
May I have the print and the output from the debugging?

I got the answer via email from NT support and want to reiterate the solution as it will help others in same situation.
I have both tick and 5 minute bars in my indicator. so if I want to call it from my strategy or market analyser, I need to add the tick and 5 minute bar in the strategy and market analyser before calling the indicator.
