instruments = [(marketfeed.MCX, "436081", marketfeed.Full)]

version = "v2"

try:
    data = marketfeed.DhanFeed(client_code, access_token, instruments, version)
    while True:
        data.run_forever()
        response = data.get_data()
        print(response)

except Exception as e:
    print(e)

I am also facing the issue of DH-905 i am testing MCX datafeed only NSE works fine i can see the feed of OHCLV but MCX throws DH-905 error code. I guess something from Dhan end ? @RahulDeshpande
