following websocket index, it happens that prices are:

not updated afer few seconds
the meantime between two received prices seems high (2s) and it increase

other:

between 40-50 trading pairs monitored

could be related to the soft itself. Threading in Python is concurrency / not parrallel, means since arbitrage is in a while loop running as fast as possible: there is a lack of time letting time to other thrad to run which can cause server to disconnect

Data manipulation takes time so connection is lost.

Should try:

multiprocess sharing data: fail using pipe on msg. Why ? Give a try on local variable
fork a process into websocket process (https://stackoverflow.com/questions/1268252/possible-to-share-in-memory-data-between-2-separate-processes )
