Display value from Market Analyzer column to chart as text

[cyberpete76]

Hi, I have this code for an indicator, that should display a value from a column on the Market Analyzer onto a chart.
The code is still in development, but I got stuck on line 48 (notes2 = MarketAnalyzer.CurrentInstrument.FullName, as the compiler gives me error mesage code CS0103:

Hope it is possible to access data from the Market Analyzer according to the linked instrument or any of the specified instruments on the Market Analyzer at all?

Thanks

Hello cyberpete76,

What data are you trying to access? You can't access the market analyzer directly to get data but you can in general get the data it uses. You can also view each of the columns code in the NinjaScript editor if you wanted to see how it collects data.

I need to collect values I am typing into a column, which is a simple Note (Notes 2 from my screenshot, to be precise)

Hello cyberpete76,

There wouldn't be a way to pass that information to a chart, charts have no means of communicating with columns in the analyzer window. You can launch a chart from the analyzer to the instrument and that chart can have indicators on it but the only data shared between the analyzer and the chart would be the instrument and timeframe based on the linking settings. If you need notes in a chart you would need to use a notes indicator and type in notes to the chart instead of the analyzer.
