How come that with every trade i do, the outcome is always the opposite?
When i buy, market goes down...when i sell, market goes up...strange
That's not strange.
It happens to most traders but it is very unusual if you happen to experience that most of the time. Learn with those experiences that you've gained. It's not all the time that you'll be having the losses and opposite result when you trade.
If trading isn't good for you, then just become an investor that holds and sells if necessary.
