Exactly! I follow the principle of the great investor Warren Buffet when it comes to the investment. He says, "Be fearful when others are greedy and be greedy when others are fearful" so according to this principle, it's time to buy when the market is showing downtrend since the last couple of months. That's the difference I noticed in between experienced traders and newbies over the years.
I think this situation only work at sometimes and it can't be used at all scenarios , it only works when it has enough the conditions for it like the market is falling down without a reason or just only some bad news were coming from goverments. But right now, bad news were not only coming from the goverments, it's from the investors also. That will make the huge different.
