How to send data to TickerPlant

[hzad...@gmail.com]

Hi, Masters:

  I had completed the test of kdb+tick demo. And completed the workflow of using PyRFA to get Realtime data from TREP(Thomson Reuters's system to provide data).  According to the kdb+tick demo, the data was simulated by feedsim which is a q script to generate data, it's easy to understand and implement the connection to TickerPlant.  But one thing I don't konw how to resolve is how to feed the realtime data to TickerPlant with Python platform?

  Many thanks for your suggestions!

Thanks

Zheng

Hi,

  So far, I'm trying to use qpython to make the connection. and then, require data from kdb+.

  The 3rd step is feed real time data into TP.

  How about other opinions?

There are both q connection support and q-embedded support in Python. You can pick a suitable on to send your Python side of data into Tickerplant.

@see http://code.kx.com/q/developer/#foreign-interfaces

qpython is a good choice. There's an example of publishing to a tickerplant here:
http://qpython.readthedocs.io/en/latest/usage-examples.html#data-publisher

In this case, the line doing the publishing (i.e. calling .u.upd in the TP process) into the 'ask' table is:

self.q.sync('.u.upd', numpy.string_('ask'), self.get_ask_data())

Hi, James:

  Thanks! After testing, the data flow works.
