Whether you are a day trader or you trade once in a while, you have to align yourself with the smart money, not the dumb money, surf along side the whales,not against them, trading is war and you have to choose your battles correctly
When the market becomes bearish, thats the perfect time to hit and buy more with your money while you continue to wait for the bull run. Some people also decide to wait to be very sure that its bull time so they can then get in and go with it. But sometimes it ends up being a Bull trap, cause it might drop when you have invested.
