What is your biggest financial mistake in 2020? What did you do to rectify or recover from it?

Here is my biggest mistake in 2020-

After the market sell off in March, we had a big USD rally due to liquidity issues. I placed a large sized bet with UUP etf using a call option with strike price of 28, hoping UUP to rally from 26.5. I lost SGD13K in single trade over 3 months.

There are many lessons i learnt from that trade-

1) leading up to the trade i made a huge fortune from my TLT trade which gave me 400% profits leading up to the crash. Every single projection worked in my favor and i was very confident in my approach. That overconfidence lead me to take a big trade in my next trade as well.

2) Position size was too large to start with..again this is because of over confidence this was my biggest mistake.

3) Never fight the FED- I was not expecting huge stimulus package from FED to offset USD strengthening. Even after FED announce unlimited QE, i assumed FED is wrong. Also, I was not paying enough attention to FED M2 supply data (which is critical when you are placing a USD currency trade)

4) Staying too long with the loosing trade eventhough i had plenty of oppertunity to get out of it.

Ha ha... I litterally did every single thing that a trader should not do.​​​

Unpopular opinion (gonna receive hate for this)

My biggest mistake was passive investing DCA. Can only make money in one direction. Up. Not taking advantage of mispricing and cheap prices. Lose along with the market going down while seeing professional traders/proprietary traders I know make big profits shorting the market and buying big near the bottom.

Ever since I started being properly trained in trading, made +43% in the past 6 months, even though I completely missed the bottom
