Changes on Bitfinex
Removal of Notify Option:
The notify feature available when placing orders or liquidity offers is being removed as it is almost never used and doesnt actually work very well in certain circumstances. We are, in general, always looking to simplify our interface and prune features that no one uses or may no longer be relevant, paving the way for us to add new features to a clean and uncluttered interface.
I really liked this feature and in my experience it always worked pretty reliable.
Sad to see you decided to remove it

(that said I of course agree that a simpler interface is always an improvement)
