You stated "(***TD if the Market Maker is a joke, as the role is to provide liquidity, 70% of which to cushion the move of the market. They are always there to provide liquidity to Sell, not so much to provide Buy Support when the selling is pervasive, supposedly their role)."
May I respectfully suggest that TD is also a low cost online broker and that they may be the broker of choice for the many day traders that have been flipping ZEN stock. Perhaps these traders have been selling this past few months (to what purpose - I don't know). That would account for the large number of "sells"
