Is there a way on Mac OS to get TOS real-time data into Excel? Specifically, I'd like to get option data into Excel. But I am curious more generally if anything is possible at this point in time. =RTD("tos.rtd", , "MARK", "AAPL") gives a "#N/A" result. Not sure if I need to specify a server. Google is not helping me except to vaguely suggest that what I am trying to do is not possible on the Mac side of things. Any guidance would be much appreciated.
