sstyles, the dark pools use the high frequency platforms to spoof the market at the close by flashing large blocks every nanosecond. It def puts a floor on the share price. Dark pools are far more in control than the retail investors and will remain till an unexpected event occurs. I can assure you that the unexpected event will not occur during trading hours that's when it'll gap up at the opening or it will start at 4 a.m. when mkts open in the EU.
