Futures is equivalent to a small-cap stock, with tens of millions of funds jumping up and down, plus two-way opening and closing positions, it is more difficult to grasp the direction of the day, and price changes are much more difficult than stocks.

If you want to figure it out, you have to be short of arms and legs.
