  1. Im sorry, I think that I might have gotten the two mixed when i wrote the first post. Since then at least, I have only experienced recieving fewer ticks in the stream, than by the GetLatestPriceTicks call. After further investigation on my own, I have concluded that any push messages recieved while the thread is busy, will be lost. So I believe my issue is that i am processing the messages as they are recieved rather than queuing them. As I am unfortunately not doing this for a living, it might be a while until i have the time to get a proper queue implemented to confirm my suspicion (and fix possibly my issue).
  2. Hi Thank toy, good to know I seem to miss between a few ticks on most 5 minute intervals, but i can see that when the number of ticks in a given interval rises, i miss more, relatively (30-50 ticks if there are ~1000 ticks/5 min, compared to missing ~3 ticks at ~500ticks/5min). Today i was connected to https://push-retail-02-089-01.cityindex.com/ and experienced the above mentioned. Unfortunately i cannot rule out that it is an issue on my side, a guess could be that the messages are not being queued correctly when recieved and so i miss some if they arrive in quick succesion. I will look into that. FYI, i am using python, with lightstreamers own python client example as basis. (They published one to github).
  3. Hi, sorry for the late reply, life sometimes gets in the way.

  4. Hi I am experiencing differences between price ticks recorded from lightstreamer, and ticks recieved from GetLastestPriceTIcks. I am finding that sometimes not all the ticks recieved from the stream during a period will be present in the data recieved when calling GetLastestPriceTIcks covering the same period. Should these sources be identical? regards
