NT7B9: Multi-series indicators are broken

[kdoren]

Yes, I know the email said we "may run into issues".... the issue being that it's completely broken...if you Add() another bar series in Initialize(), OnBarUpdate is never called, and the log shows exceptions for the "GetMinMaxValues" method.

Any estimate on when this might be working, and do you expect it will also fix the problems with multi-series strategies?

kdoren,

There are underlying issues we are working on to address it as a whole. Please do not test/use multi-series indicators at this point in time. Unfortunately I cannot give you an ETA or an evaluation on the multi-series issue. What I can tell you is that we are working on it and will let you know when it is ready for testing again. Thank you for your efforts and patience.

To clarify that we are on the same page though, which/what multi-series strategy issue are you referring to exactly? Thank you.

I also get trace and log messages

Error in GetMinMaxValues object non set to a reference

I cannot explain this from my code. The log messages show up only on one of my 2 PCs. Both have the same indicator set in use, workspace (charts, etc) are different.

zweistein,

That is what was meant by the issues you may run across when using multi-series indicators. If you are not using a multi-series indicator then that would be new and we would be interested in more information on this indicator. Thank you.

Josh, I was referring to being unable to sync a data series to a secondary bars object in a strategy.

I get this GetMinMaxValues error only at startup of NinjaTrader and there I get in in several indicators, also referring a very simple

DayOfWeekColor indicator published by me long time ago

http://www.ninjatrader-support2.com/vb/showthread.php?t=17164

could be related to a bug when using multiple dataseries in one chart.
(FDAX and Es 03-10)

The indicators with the error message are all attached in the primary dataseries of the chart (upper chartarea)

All indicators are however simple indicators of single-instrument type.

Another observation:

Seems that the GetMinMaxValues error gets only triggered when I open NinjaTrader OUTSIDE market hours, e.g. after 10.PM CET or BEFORE 8 P.M CET.

So this error could be linked to time beiing outside a session template ...

zweistein,

The DayOfWeekColor indicator worked on my machine as well as a colleagues machine without running into any errors. Please clarify the setup required to achieve a GetMinMaxValues error. Thank you.

[zweistein]

Josh,

I can reproduce the GetMinMaxValues ERROR in the log at startup.

It does not happen due to failure in DayOfWeekColor, but DayOfWeekColor will simply trigger the error:

Do the following:

1. Open a chart:
Add at least 2 dataseries to it (FDAX 03-10 and ES 03-10)
Add DayOfWeekColor.

2. Open a second chart
Add at least 2 dataseries to it (6E 03-10 and FGBL 03-10)
Add DayOfWeekColor.


3. Save the workspace and exit NinjaTrader

4. launch NinjaTrader . The log will show the exception in GetMinMaxBars.


Probably any custom indicator will trigger this error.
The error will show up only if you have a second MultiDataSeries chart.
With only 1 chart open there are no errors.

regards

EDIT:
Tried again now, and the error is complety gone.
There must be some other trigger also for this error.

Andreas,

I believe development has worked on an issue related to GetMinMax. Perhaps you could try again on the next version. Thank you.
