$BTC A very bad operation, long from 5.76, then long again at 5.66, during this rise, closed positions at 5.67 and 5.78 respectively, and panicked when it fell to 5.25 before, but fortunately only opened 5 times, and the liquidation occurred at around 4.5, so I managed to survive. This operation was mainly because the bullets were used up too early, resulting in very little room for operation
