Every Trader at one point has tried to time the market in the past, and done well. That doesn’t mean they are good at it. That means it was a lucky shot.
But 9 out of 10 times it is a loosing cause, and many have gotten caught trying to do it. Loosing almost 100% of account values.
It is a dangerous and sloppy way to trade.
Timing the market. Don’t do it.
