To sum up a method, if we are not long in a range, if we do not pull up immediately, it means that there is controversy in this range. First of all, I want to make it clear that we are long, so if we are at the bottom, we should The key to entering the market decisively is that we must repeatedly buy low and sell high to reduce our position in this volatile range. Another problem is that you increase your position once it is stepped back, and then it falls back to the original range. This What should I do? Go short in the opposite direction, and then if we go back, then we will close the position at the bottom, so that we can make a profit and make up for the loss of the long order, and then enter the market again at the bottom, because the original position was wrong. Regarding the position, because I placed the order in the opposite direction, the profit and loss were actually evened out. At most, I lost one lot and the handling fee was higher. Another point is that I need to make a decision, that is to say whether I am going long or short within this range. This cannot be changed.
