Cannot Use Custom Indicator in Strategy Builder, code is pasted

[HaveGunsWillTravel]

I coded a basic Elliot Oscillator, I have been at this for about 12hours in various ways, scouring this forum and youtube. I cant make this work. I need to pull the value(double) from this indicator into my strategy. I had another version when I had the drop menus to pick the variable from the indicator in the strategy builder, but I was still missing the data, I get this error message:

"'ElliotWaveOscilator' tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state. Attempted to load HBars Default: 600 Tick Heiken-Ashi"
itried doing extra data series and all kinds of weird stuff. this code does not even have the drop down menu working in the strategy builder, but is the cleanest version I have working on a chart. For the life of me, I cannot figure out where to pull the plot values form. I even tried doing a transparent plot like another post here said, but still couldnt get those to show up in the drop down menus of the strategy builder so i could use them.

This is the cleanest version of code that works perfectly on my chart as an indicator. thank you for any help I am exhausted and I am sure I am missing something basic. Feel free to use if useful to you.
Here is a pic of it working on chart...

Hello HaveGunsWillTravel,

Thanks for your post.

The error message, "'ElliotWaveOscilator' tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state. Attempted to load HBars Default: 600 Tick Heiken-Ashi"" Is caused when a script requests bars inside of another script. In this case, the indicator is requesting HBars and the Strategy is the host of the indicator and the strategy is required to provide that data. Typical use of AddDataSeries would be to add for example a 1 tick series to the indicator and in that case the strategy must provide that 1 tick series.

In this case the indicator is generating the HBars so you have a natural conflict here. Please remove the line AddDataSeries("HBars");

With that removed you should be able to recompile the indicator. When you use the indicator in the Strategy Builder you should be able to get the HBars from the indicator as these are a plot which is what the Strategy Builder needs. When you open the indicators folder in the conditions builder of the strategy builder you should see plot field showing HBars so when the indicator is used it will return the value of HBar. You can always construct a Print statement to show this in the strategy builder in the action section with Misc>Print and then select the indicator.

My god it seems to be working, I could cry. Thank you.

[HaveGunsWillTravel]

For my learning purposes, what was I doing wrong in terms of referencing data? Was I trying to force a call somewhere weird by inserting that data series add? How and where is it calling the value of the oscillator<double> now, in its working state? thanks again.

Hello HaveGunsWillTravel,

Thanks for your reply.

AddDataSeries would be for adding other bars to your script. The HBars data series was not created until you ran your indicator so it was trying to add something that was not available and it appears to have defaulted to 600 Tick Heiken-Ashi.

When you select the indicator in the strategy builder and create a condition with it, that is where the indicator is called and it returns the value of the plot HBars. Note: FYI - if you have a multi-plot indicator such as a Bollinger, you would have to select which plot to be used as the "Value Plot" (in that condition).
