A typical Dead Rat Bounce occurs when a stock cuntsumates the uptrend and begins down trend.
After about 20% fall,,, a brief and violent upshoot occurs which quickly dies down and that is called Dead Rat Bounce. You can comfortably short that stock when it DRBs.
And I haven't confirmed cunsummation and subsequent fall yet.
I suggest you put a mirror in front of the LCD and look at the chart in the mirror or put the LCD upside down.
