@Moderator_3 Is there any update? I am also facing the same issue. placed order and cancelled order is not reflected in smartwebsocketorderupdate.

@Moderator_2 add on more function like below

def _on_close(wsapp,code,reason):
      on_close(wsapp)

and add this function to sws object like below

sws._on_close=_on_close

Above lines of code will resolve the issue of error during close.
