The biggest mistake I've made while trading was getting too excited with the day trading of $BioNTech (BNTX.US)$ during the earnings report release period.
I bought $BioNTech (BNTX.US)$ very near the historical high and I failed to cut my losses when it fell to the 300s mark. So now I'm just waiting for $BioNTech (BNTX.US)$ to bounce back up to the mid 400s so that I can start afresh with, my limited capital. See below for my position chart

(ONE)
My 1st ever trade was just 2 lots of $SGX (S68.SG)$ because I didn't have much capital to play with and it sounded safer to dabble in the SG market than overseas markets.
I later tried trading in $OCBC Bank (O39.SG)$ at 2 lots too but volitility was very low, just like SGX although I made just a few bucks in the SG market as a whole.
After a few months in the SG market, i decided to sell all my SG stocks and trade in the US market. I tried $Tesla (TSLA.US)$ and it was a great start because volitility was much better than the SG market.
I later pumped more capital into my US account to trade in $BioNTech (BNTX.US)$ and #MRNA as they seemed to have longer candles based on the graphs. Volitility was also high which made me happy as a day trader. All in all, #BNTX has given me the most returns. My highlight for 2021 will probably be buying #BNTX at its all time high and now I'm just holding on to it and waiting for it to rise again.

The best learning point i have gotten in 2021 is not to panic sell. As Warren Buffet said, "Never lose money" Something crazy I have done is probably the fact that I, stayed up at night in SG, day trading during the US Market opening hours.
It was very exciting to hear the coins notification sound on my moomoo trading software in my laptop when closing my positions as a say trader.
