For novices, two firewalls can be set up at the defense point of contract currency:

1. Half of the profit

2. Near the cost

Make your own arrangements based on your own conditions and risk tolerance.

For contracts, there is nothing you can do if you are quickly hit by a loss as soon as you buy it; if you start making profits as soon as you buy it, you cannot make a loss on a profitable order.

It is better to make less money and miss out on big profits due to strict risk control, than to put the principal in danger.

After all, the market never lacks opportunities.​​​
