How to make profits?
Even if the value of the futures contract changes by 5%, your capital will double or lose money.
If you lose, is it possible to lose more than 5W?
I will.
If the contract value stops in a direction unfavorable to you (usually 5%) after you open the position, your deposit will be lost. If you stop trading continuously (can't close your position), you will continue to lose money. If you stop trading for three times in a row (each stop is calculated at 5%), the exchange will generally arrange the loss-making customers to close their positions. You can pay about 15W, and you are obliged to pay about 10W to make up for the loss.
In order to avoid the above situation, in fact, the margin ratio of futures companies is relatively high at present, which is generally 10%- 15%. That is, the capital has been enlarged by 7- 10 times.
