If trading is this simple formula, then no one will lose money in it. Normal futures fluctuations are relatively small, with an amplitude of about 2% a day. Because futures are leveraged and the handling fee is relatively low, there is still a lot of room for operation. But you must not operate according to the above formula. Because many times, the stop loss is set and the take profit is put away. It is not uncommon for people to make profits at first, fail to take profit, and often break through the stop loss. Therefore, it is still necessary to put it in accordance with technology and mentality and do it in a down-to-earth manner. Opportunism will not have much effect.
