Will do a brief decade review soon.

But generally speaking, it's being far more difficult to make money now than around 2018 to 2019. For discretionary trading perhaps the winning rate already dropped to 50% and for algo based, nearly none of the old strategies can generate stable profit (parameters need to be changed all the time but thanks to DL the parameters can be auto-updated in an easier way but still very challenging because of outliers and new policies - maybe adding a discretionary "temperature" parameter could be helpful just like GPT's API?)

Maybe with GPT some new text based strategies can be found. I will open source what I found after making or losing enough money.
