The only way to win a contract is... There is an unlimited amount of money to add to the position. It sounds unlikely, but there is a trick to make unlimited money: 1. Choose the direction for the first time you open a position, and the margin is about 10%. 2. Every time the support and resistance level is increased, 25% of the remaining margin. 3. A limit order with 25% of the remaining margin is placed near the liquidation price to prevent accidental liquidation.
