As expected, Bao Er Ye was right. When you play contracts, he lets you lose money when you buy, stops you out, then when you buy again, he still lets you lose money. Whenever you stop buying, it goes up, and when you buy, it still lets you lose money. It's as if the market is watching you. This is typical point demolition, it's disgusting. I want to know who the hell invented this. You can only play mid to long-term. When I play ultra-short-term, I am a dog.
