Open a position for a futures mobile phone series

1. The correctness of opening a position directly affects the success or failure of an operation, and it is also important to choose the timing of opening a position. First of all, we should look at the trend of the market, try to choose the direction that is consistent with the trend of the market, and have a high success rate in the case of following the trend. The second is to choose the timing of opening a position as much as possible at the time of the conversion of a band, so that you can strive to be in a safe position and not easy to be liquidated. Again, there is the question of the size of the open position. If the one-time opening position is too large, it is difficult to recover if it is done in the opposite direction, and you can open a position with a small and medium-sized amount, specifically one-third of the total investment at a time, and the remaining funds are used to increase the position.
