Every day, open a short-term contract trading position, the key is whether the resistance level is broken or not, which affects the average cost of the next position. For example, today ETH did not reach the target of 3506, and 30% of the position set at this level for take profit was not successful. The open position cost is 3366, so when the pullback starts, manually take profit directly, instead of waiting for the price to drop below the open position cost before considering margin replenishment, which will affect the next average cost. Do you understand this situation? If it is determined that the resistance level will be broken, keep an eye on 20-30%, and take profit near the next resistance point or new high. If there is no breakthrough and a quick pullback, handle it in time. Don't leave any tail, take profit in batches every day, clean and neat, for stability. The winning rate will also increase unprecedentedly.
