It's actually very simple. Generally, I use all-in (rolling the same coin), but I prefer to use separate positions (rolling different coins). As is well known, the return = leverage × price fluctuation. With a 1% increase and 100 times leverage, theoretically, you can achieve a risk-reward ratio of 1:1, which means doubling your investment. If you start with 10u, you just need to open a separate position, choose a certain coin, set a 1:1 risk-reward ratio for taking profits, and then get 20u. With 20u, you can go all in again, open the same leverage, and with the same price fluctuation, you will have 40u, 80u, and so on. In an all-in mode, you can just add more once you have floating profits (but there is a bug that if you break through the add position point and then suddenly pull back, the profit can't be added back, and even if you add, the risk of liquidation is high), so I prefer the separate position mode to roll, and then chase shorts or chase highs.
