We're currently working on a NIP which publishes Market Prices and Symbol List into an ADH.
You could use the example270__SymbolList example of the Elektron SDK Java for that. To do so, you just have to change the name of service and symbol list in the Consumer.java file (line 176) and then build the Elektron Message API examples (EMA). Building the examples is quite easy. This is explained in the Elektron Message API Java Quick Start. The Elektron SDK and related examples are available for download here. Once the SDK downloaded, you will find example270 in this folder: Ema\Src\examples\java\com\thomsonreuters\ema\examples\training\consumer\series200\example270__SymbolList
