I closed my wife's long orders in a daze early in the morning, and the contract grid was gone. When I woke up, I was slapping my legs, but I didn't regret it. As long as you are in this circle, there will always be opportunities. You can make orders as big as your capital. I don't have unlimited capital, and I am even in debt, so I have a stop loss for each order, and the profit will be set at the appropriate position (I think it is appropriate) to protect the principal. If you have unlimited capital, as long as you control your position well, you can win! It's almost there, it's almost doubling~^_^
