Oh, basically the bounce doesn't come and the liquidation takes it's toll. Like being sucked into a ventilation shaft . You're hanging on by your fingers and for a moment you think you might survive, until another victim slams into you and you both hit the fan and are extruded into the abyss.
I hope that answers your question. Have a nice day.
Since the market consists of only "entry" and "exits" - whether they are buys first or sells first, the term follow through can apply to either direction. Big seller one day, followed up by another big seller the next day.
