I just created a sample to demonstrate a problem. I have a custom value in my indicator that I want to print in my custommarketanalyser column. I get the following error whenever I use it.
A hosted indicator tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state.

I read thro all the forums before posting this thread....,.
I have my code running only when the state=State.realtime. there is a implicit assumption that the market data is already loaded when this happens. so the only theory I have is that there is a bug in the NT core. this is why I created a simple representation of the problem so the NT folks can see the problem and fix it.

Hello junkone, and thank you for your question.

I noticed your code relies on the proprietary file STSVer2.cs . Would it be possible for you to prepare code samples that do not rely on this? If not, and this is an indicator you own the rights to, would you be willing to send a copy to platformsupport[at]ninjatrader[dot]com referencing this unique number in the body of your e-mail : 1518806 ? If neither of these is possible, we will not be able to use your code sample, as we can not get it to compile in our end. In this event, could you generally describe in plain language what we would need to do to reproduce this?

Thank you for helping us make NinjaTrader 8 better.
