Does the TRML allow for near-realtime stock tracking + allow to be plugged in 24/7

Have not bought one yet but if i just bought the trmnl x - can this be plugged in 24/7 to avoid battery drain and if i used the stock recipes like the Etoro one: https://trmnl.com/recipes/253167

Would this device allow the portfolio value to be refreshed near real time i.e every couple of seconds etc? Thanks
