We should trust our experience in trading even though the situations got worst, and I don't think panic selling is the solution. What will happen to your future profit if you sell it all due to you're panicked? That's why we should stay stronger and keep the faith burning so we could stand against negative speculators.
Panic and greed are the most serious enemies of the trader .But I know there were times when the panic has saved me(it was long ago when I was not experienced ) Now I go to the market only when I am confident in it,and I'm ready for all outcomes .
