I made two serious mistakes today.

The first was recklessly opening a position due to my arrogance and adding to my position without strictly following trading discipline.

The second was due to greed; I didn't exit at break-even and was still hoping to make a bit more profit, which caused me to miss the opportunity to cut losses, resulting in significant losses.

This record serves as a reminder for all of us.

I will never repeat these mistakes again, otherwise I will not engage in trading anymore.
