I have watched the trading advice of so called 'experts' for years and I have came to the conclusion the best policy is to take a contradictory position.
There's a guy (I think it's a guy, but am not positive) named stock_trd3r on here.
If you take a contrary position to his, you'll always bank money.
From time to time, he's quiet, but that's only when the markets are in freefall.
When things stabilize a little, he comes out and screams buy.
It's like playing an easy game of whack-a-mole.
