It's not toxic, it's just messing with you. I've played it a few times too. The prices are clearly correct, the K-line chart prices are normal, but the closing price is just a loss. Don't play this anymore.

Event contracts are toxic!
I don't know if the system is messing with me, or if I'm just incredibly unlucky.
It's gone to zero. Without further ado, I'm getting back to it, look at the picture.
If you say my judgment is off, I admit it, but three times in a row, just a few U in the last few seconds, that's too absurd, right?????
