99% of people completely don't understand true position rolling!

If you're still using the basic method of "buy low, sell high," you'll never make big money!
The ultimate core of position rolling is: profit compound interest, not adding to the principal! This is also the root cause of 90% of people getting liquidated—after profit, wildly adding to the principal, and a wave of pullback directly resets to zero.
Correct operation: use 5% of the initial position to test the waters (use 150U out of 3000U), after a 30% profit, only add to the position with the profit, never touch the principal; each additional position should not exceed 50% of the previous position to avoid profit retracement; after doubling the account, immediately withdraw the principal to stabilize your mindset.
Three deadly mistakes must be avoided: going all-in immediately after profit, the market maker is just waiting for you to get greedy and take the bait; adding to the position with floating profit but not stop-lossing, a wave of reverse fluctuation will lead to liquidation; greedily holding overnight, 3 a.m. is the golden time for big players to dump, holding overnight is equivalent to courting death.
There are also 3 details that 90% of people overlook, leading to liquidation: when profit reaches 50%, always set a 1% profit protection order to prevent profit retracement; clear positions at 3 a.m. to avoid market dumps; in case of sudden disconnection by the exchange, be sure to hedge to avoid unexpected liquidation.
