Many people play contracts to make a lot of money with a small bank, and there are only two ways to make a lot of money:

First, the Position wins, the Heavy Position;
The second is to win by amplitude, the market has a large enough movement amplitude, such as 312, 519 kind of big fall, such as 1W up to 6W this kind of big rise, want to hold this amplitude, no analysis is useless,
There is only one trick: more than profit, the most clever way to take profit is more than profit, but more than profit is extremely anti-human, 100 times or even 90 times will lose or not lose or not earn, I can't do it.
If the Position is small, no matter how large the amplitude is, it will not make a lot of money, and if the Position is large, it is useless if the amplitude is small, and it is easier to Get Liquidated; Anyone who makes a lot of money is a master at balancing the two
