.299; .516; etc. What is happening here is a strategy of coordinated signaling either by multiple buyer/sellers or even (as I have seen before) by the same buyer/seller with multiple accounts who trades with himself. The odd pricing is a way to ensure that one knows it is the other bid/asking and that any exchange is self contained without any actual loss but with the ability to control the share price. This is market rigging without question and to the degree it is coordinated is most likely a RICO violation, eh Elsie? But I assume you know that.
