Your plant is definitely, without a doubt, a blooming sized miniature Dendrobium. They don't get much bigger than the one you have.
They go deciduous sometime in mid - late fall.
Drastically reduce watering when they go deciduous, as that is when they are dormant.
Blooming season is very late summer - early fall. Inflorescence is usually produced from the apex of new growths. I have not seen an old pseudobulb produce blooms before.
They also have a tendency to throw out keikis a lot.
