After all the big tag buys, the pps is still stagn

After all the big tag buys, the pps is still stagnant. There is an obvious attempt to prevent the PPS to increase. For what purpose? Also, I don't know how they do to show some big buys as sales (red). MM manipulation to keep the price down but for who and for how long? This kind of action remembers me of Sirius Satellite radio back in 09. Good like fellow longs,
