    kws.unsubscribe(instrument_tokens)
    You need to use ws.unsubscribe(tokens) to unsubscribe required token/list of tokens.

    @rakeshr i am not unsubscribing inside a callback if that is what you are referring to . but in a separate function which is being called by another py importing 'myticker'

    You need to paste the WebSocket code, for us to debug this further. From the above stack trace, it looks like you are not calling unsubscribe method properly.
