Time flies and it is already the end of this year. I sell lot of stocks this year to secure my gain. I worry many institution investors may rig the market at the end of year. It's hard to count days when trading stocks.
I lost a lot last December when the institutions are selling their potions. Then I won some real money at the begining of 2020.
However I was too greedy to withdraw from the market before March. The Black Swan event in March cost me lots of money. I then use day-trade to make up my lose. I became a money-loser both in June and September.
