Usually nothing happens on Fridays, even with news Fridays could be quite the full day. It's all for profit taking for the weekend, little sells for liquor.
Don't second guess yourself. Yes, pinks can explode to the positive side but mostly they implode.Most often the MMs grease the skids by walking a stock up slowly over time only to sell off and watch as investors try to get a few crumbs of profit as the PPS rapidly falls (and the MMs refill their coffers with cheapies).
I am slowly learning how to gauge such things so I can sometimes take my profit before the MMs do. The odds remain against me...as they are for you. Watch and learn...a process that is often quite painful. Good investing.
