I’ve tried, but it doesn’t work, everything in the example is nearly right but not quiet right.

In the example is says

from lightstreamer.client import *

That doesn’t work, it needs

from lightstreamer_client import *

In the example,

sub = Subscription("MERGE",["item1","item2","item3"],["stock_name","last_price"])

It errors because Subscription is not defined.

I get round it using

subscription_data = LightstreamerSubscription("MERGE", ['MARKET:IX.D.FTSE.CFD.IP'], ['BID'])

etc etc.

Hence I wonder if the example is written on a very old version of the code.
