Underlying Event usage

[Clint128]

Have been trying to use the underlying event in streamer to get futures call volume and put volume respective to the each option based on said options streamer symbol. My program pauses every time I try to implement this. I've tried to look for the correct usage of the underlying event and the symbology needed,but haven't found anything so far. Was hoping for an example.

I just played around with it a bit but I couldn't get it to work. I suspect it's no longer supported, especially since a year or so ago I was able to get it to work. Officially it was never part of Tasty's dxfeed package anyways, I remember the API team being surprised SDK users were able to get some of those events like Underlying, TheoPrice, TimeAndSale.

I may be wrong though! See if you can play around with the streamer and get it to work. You'd need a new function similar to subscribe_candle but for different time series events. There might be dxfeed examples in a different language somewhere on the web.

Okay okay, yeah I'll try to do some more research and testing. Appreciate the feedback
