First of all, the capital for the first opening can't exceed 20%, which is the trial operation stage. If the direction is right and it runs as expected, you can consider continuing to add positions, and the funds for the second position should not exceed 15%. If the direction is correct, the funds for the third opening shall not exceed 10%, and the accumulated funds for each opening shall be reduced, and shall not exceed the total funds at most.

Secondly, we must control the stop loss and stop loss. Every time you add a position, you must move the profit price to ensure the due profit. In case the direction is reversed, we can leave calmly. Take profit and stop loss strictly.
