What is the current Lightstreamer server version in use?


NovoPDNK

Question

Hi,

 

I'm try to play with new official LIghtstreamer Python client lib and it fails with "Cause: 65 - Unsupported protocol version". My best guess is that's happening because the SDK requires server version 7.2.0, whilst IG has something older. Could you please confirm what's the current server version, and if it's lower than 7.2.0 is there a plan for upgrade?

 

Cheers,

Novo

Hi, @OfentseIG, thanks, I did. 

There are some subtilties and the page require a few update on the Python side.

1 st point, now Lightstreamer does support a python library (yeahhh) but... Ig Lightstreamer server does not support it (looks like licensing version issue - time to update?)

2. Then now the python sample in github is actually leveraging the standard python in the main branch. https://github.com/Lightstreamer/Lightstreamer-example-StockList-client-python/blob/master/src/stock_list_demo.py

and so at the moment, this does not work with IG.

3. BUT, We are not out of luck! If you are looking for the python code which enable txt connection to the lightstreamer server, you can still use the old version of the python sample, just reference the actual old branch:

https://github.com/Lightstreamer/Lightstreamer-example-StockList-client-python/releases/tag/v1.1

 

Cheers,

Arnaud

Any updates here? Anyone knows which version of Lightstreamer IG is currently using, and what their upgrade cycle is like.


I noticed Lightstreamer released a new sdk library (https://github.com/Lightstreamer/Lightstreamer-lib-client-haxe) for connecting to lightstreamer servers version 7.4.0 and above, seeing as they have issues with their older dotnet versions i'm really looking forward to IG upgrading in the future.

Latest version 5.1.8 of the dotnet client i can get connecting to IG, but it suffers from memory leaks upon connection failures.

When will Netflix share its latest earnings information? Netflix will reveal its April through June 2024 financial results after the stock market closes on Thursday, 18 July 2024. Another Netflix revenue increase seems to be on the cards Netflix expects its revenue to increase 16% year-over-year (YoY) to $9.49 billion in the second quarter of 2024 but analysts predict Netflix's Q2 revenue will be slightly higher at $9.53 billion. In the first quarter of 2024, Netflix's revenue was $9.37 billion, up 15% from the prior year. Earnings are also expected to rise Regarding earnings, Netflix forecasts net income of $2.06 billion, or $4.68 per share, for the second quarter of 2024 whereas analysts estimate Netflix's Q2 earnings per share will reach $4.74. For comparison, in Q2 2023, Netflix reported a net income of $1.48 billion, or $3.29 per share. Netflix's net income in quarter 1 (Q1) 2024 was $2.3 billion, or $5.28 per share.

Netflix sales revenue chart   Source: TradingEconomics For Q2 2024, Netflix forecasts $2.52 billion in operating income and 26.6% operating margin, versus $1.82 billion and 22.3% in Q2 2023. This compares to Q1 2024 operating income of $2.63 billion and operating margin of 28.1%. LSEG Data & Analytics analyst Netflix recommendations LSEG Data & Analytics data shows a consensus analyst rating of ‘buy’ for Netflix – 11 strong buy, 18 buy, 16 hold and 1 sell (as of 10 July 2024).   Source: Refinitiv Netflix – technical view The Netflix share price, up over 45% year-to-date, is approaching its November 2021 record high at $700.99 which, since it was made near the major psychological $700 mark, probably won’t be easily overcome. Netflix monthly chart   Source: TradingView.com A rise above the $700.99 all-time high would allow for the $750 region to be in focus, though. On the daily chart, the Netflix share price has been range bound since late June but last week did rise to its current July high at $697.49, close to the $700.99 record peak. The upside is being supported by the May-to-July uptrend line at $678.42 below which good support can be spotted between the May high and the late June and early July lows at $633.78 to $662.30. While this area underpins, the short-term uptrend will remain valid. Netflix daily chart   Source: TradingView.com For a medium-term top to be formed, the Netflix share price would have to fall through its $626.44 June low. Slightly above this level, the April high at $639.00 would be expected to offer support in such a scenario.
