Python client for lightstreamer

Hello Gianluca - yes, that's what I did. I just sent you a pm with the commands and the server messages. I believe that should be helpful for you. Thanks!

Ok William,

I've misinterpreted MYLSSESSIONID (very similar to MYSESSIONID), sorry...

The commands seem right, but with no direct access to the system is very hard to understand what goes wrong.
If it is ok for you, send me via private mail your credentials in order to reproduce the case.

Regards,
Gianluca.

Hi William,

issues are involved in LS_id and LS_schema parameters. It's not clear to me how many different items and related field schemas are available from Cityindex, but reading through their forum, it seems the following should work:

LS_id=PRICE.400616114
LS_schema=MarketId%20TickDate%20Bid%20Offer%20Pric e

Here the Python version:

<br /> subscription = Subscription( <br /> adapter="PRICES", <br /> mode="MERGE", <br /> items=["PRICE.400616114"],<br /> fields=["MarketId", "TickDate", "Bid", "Offer", "Price"] <br /> ) <br /> <br /> # A simple function acting as a Subscription listener <br /> def on_item_update(item_update): <br /> print("{MarketId}, {TickDate}, {Bid}, {Offer}, {Price}".format(**item_update["values"]))

Let me know.
Gianluca

Hello Gianluca - this is excellent! With your help I got both the plain curl commands working as well as the python script, which I will use for my purposes down the line. Thanks so much! I will continue with the implementation with other parts, that are more broker-specific, and I will post a working code soon. Thanks again,

William
