Rolling, which sounds scary, is actually just a common method in futures trading. Another way to say it is to add floating profit, which sounds much better.
Although rolling sounds a bit scary, in fact, as long as you master the skills, you can use it more safely in the currency circle. In futures trading, the use of rolling needs to follow some principles.
First, you don't have to maintain too high leverage, two or three times is enough. Secondly, rolling needs to be done at the right time. Usually, the chances of winning are relatively high only in the following three situations: choosing the direction after a long-term sideways volatility low, buying the bottom after a big rise in the bull market, and breaking through the major resistance/support level of the weekly level.
In these cases, after making a large profit by leveraging leverage, the overall leverage is passively reduced. In order to achieve the compound profit effect, the trend position can be increased at the right time. This is the process of rolling.
Although rolling sounds tempting, remember not to blindly follow the trend. You must rationally analyze the market trend and make cautious decisions.
