what should I consider Google Panda, or Minux X penalty ?
It's only Panda if it happened precisely on a Panda date.
If you suspect a Minus X penalty, identify anything that can be perceived as manipulative, and fix it. Then file a Reconsideration Request. Assuming you get a response, you will know if you are suffering from any "manual actions" or not. If not, it's not a Minus X.
The plain fact is, loss of rankings is usually down to algorithmic re-evaluation of the normal kind. Essentially, the current algo recipe thinks you are 0.000001% less good than before, relative to the competition.
But google panda takes all your traffic right ? Even X penalties as well ?
In a word, no.
Panda modifies your score, which in turn impacts your rank. Your loss of rank then impacts your traffic. I imagine you could suffer Panda and Manual Actions at the same time, but either or both will result in a loss of traffic due to massively reduced exposure.
