there is no need for traders if there are no investors in this market...nobody buys or sells. there is no real investors in the open market...all daytraders and traders. and trading robots trading with each other. abandon market and shut down the exchange. the open market is like before so many dark pools ECN it not real market anymore. even playboy is going private..not worth spending $500,000 /year to be public company if there is only one retail investor.
