How to roll positions:

1. Adding positions with floating profits: This is the most common way to roll positions. On the basis of your existing profits, wait until the market pulls back or confirms that the trend continues, and then increase your positions. But note that when adding positions, you must ensure that the overall holding cost has been reduced, thereby reducing the risk of possible losses in the future.

2. Base position + T roll position: Divide the position into base position and roll position. For example, leave a part of the position unchanged as the base position, and the other part of the position is sold high and bought low according to market fluctuations. This can not only ensure a stable position, but also reduce costs and amplify profits through rolling operations.
