99% of people don’t understand true roll-trading at all!

If you’re still using “buy low and sell high” like that—an amateur move—you’ll never make real big money!
The ultimate core of roll-trading is: profit compounding, not adding to the principal! This is also the root cause of 90% of people getting liquidated—after they become profitable, they crazily keep adding more principal, and after a pullback wave, it goes to zero directly.
The correct way to do it: use a 5% first position to test the waters (if you have 3000U, use 150U). After a 30% profit, only add positions using the profits—never touch the principal. Each time you add, it must not exceed 50% of the previous position, to avoid giving back profits. After your account doubles, immediately withdraw the principal, and your mindset will instantly stabilize.
You must avoid these three deadly mistakes: after you turn a profit, going all-in—market makers are just waiting for you to get emotional and become the next bag holder; adding to your floating gains without a stop-loss—one wave in the opposite direction can liquidate you; being greedy overnight—3 a.m. is the golden time when big players smash the market, and holding overnight is basically asking for death.
There are also 3 details that 90% of people ignore and then get liquidated: when your profit hits 50%, you must place a 1% profit protection order to prevent profit retracement; at 3 a.m., you must clear your positions to avoid dump risk; when the exchange suddenly “pulls the plug” with a platform shutdown or network interruption, be sure to hedge to avoid an unexpected liquidation.
