CSV Market Data Adapter in Photon

Hi,

I've copied mdata-csv-1.0-SNAPSHOT.jar file into the Photon/plugins directory and restarted all components but still can't see the feed under Preferences -> Market Data. Any ideas on what more I need to do?

Thanks

Try going to photon/features/ and playing around with one of the feature.xml files. This is where the photon plugins are specified.

Edit: Also make sure the feed is compiled as an Eclipse plugin.

There are a few magic incantations that are necessary. Let me know if you're still having trouble.

Ref: http://www.marketcetera.org/confluence/display/MOL/CSV+Market+Data+Adapter

With reference to the "Easy Way" set of instructions found under "Documentation", the initial instruction is:
"Place the attached mdata-csv-1.0-SNAPSHOT.jar file in the strategyagent/modules/jar directory."

From the attached screenshot you can see there is no "modules" or "jar" folder under the "strategyagent" folder, as downloaded from source control. Are these to be added manually?

The subsequent instruction is:
"Unzip the attached sample-strategyagent-csv-files.zip file under your <metc>/strategyagent directory to get the configuration and sample scripts to run a strategy with a CSV market data adapter."

However, "strategyagent" is not a subfolder of the project root <metc>. Is the correct path "<metc>/source/strategyagent"?
Also, the zip contains a "modules" subfolder (see second screenshot), which will cause one to be created under "<metc>/source/strategyagent". If this is the intent, the "jar" folder (cited above) will still not be created.

Finally, the instruction:
"Run the following Strategy Agent command to start (you may need to have the ORS running, depending on your SA setup):"
"windows:> bin\strategyagent.bat samples\commands/MarketData-csv.txt"

There appears to be no "strategyagent.bat" in the entire project folder structure, as downloaded from source control.

The instructions are for the installed version of Marketcetera where all these are true. It's rather more complicated to run from source. Use source/strategyagent/src/test/cmd_exec for the root (find modules/jars, etc under that). To execute, from the strategyagent directory say "mvn -Pexecute exec:java".

After downloading the jar/zip files and unzipping the zip file, I ran into an error, as shown below, when I executed this command:

I double-checked the jar file is under modules/jars, and both GOOG.csv and market_data_csv.rb are under samples/scripts, which is refered by ".DataDirectory" variable in modules/conf/mdata_contrib_csv.properties.

If you know what happened here, please let me know. My platform is Redhat 2.6.18 on x86_64 machine.

Thanks.

It looks like there are two problems. One is that your strategy invokes a method "newRequest" that doesn't exist. The other is that your strategy agent command file probably has the wrong URN to invoke the CSV module. I don't have the code in front of me for this version of the CSV module. What URN does it assert (in code) in its module factory?

The instance URN in its module factory code is metc:mdata:contrib_csv:single.

The newRequest() error can be solved by replacing the MarketDataRequest.newRequest() with MarketDataRequestBuilder.newRequest() and related imports ...

Hi, I follow every step to implement my own feed. I verify the files and rename everything. I put the jar on plugins and it modify the profiles.xml file under features folder.

What's the magic here?

Difficult question to answer, grasshopper. What problem are you having?

Thanks for answer Colin!

my problem is that I implement, build and package my
custom data feed. Following each advice on this post. But I can't see my custom feed under Preferences -> Market Data

anybody fix this problem?

Are you running from Eclipse or an installed version of Photon?

I'm running from an installed version of Photon.

Stupid question, then, did you copy your plugin to the installed plugins directory?
