Couldn’t find any direct corelation with any product
When subscribing to a feed using the ‘full’ method, it’s indicated by ‘FF’, signifying a full feed. Similarly, if you subscribe using the ‘ltpc’ method, the key values will be altered to ‘ltpc’.
We plan to include this information in the documentation in future releases.
so we shouldn’t expect it in the instrument list I guess !! Only used for subscription and market watch updates ? correct ?
