Hi all,

We are looking to utilize LightStreamer for delivering different types of market data to our customers.
In dealing with option chains I was hoping to get some advice on how to optimally handle the process of receiving a single item expanding the list and subscribing to the variable number of options associated to that chain.

One such solution I can think of is for the metadata adapter to make a call to our back end to determine the list of options and pass them back to LS, so LS sets up individual subscriptions for each to the data adapter. Just wondering if there is a better solution using the data adapter to establish and manage the list associated to the chain?

Thanks in advance.
