The specific method is to recharge 200 yuan each time, which is about a little over 27u. Then the target is 100u, looking for some popular contracts to start, playing those with large trading volumes. First, invest 1u, and as the price goes up or down, gradually increase the position to continue making profits. If the direction goes wrong and after increasing the position once the loss reaches 5u, please cut the loss in time, or set a stop-loss point immediately after each order. As long as the principal does not incur losses, keep going until the funds reach 100u, then increase the margin to maximize profits. If the direction of going long or short is wrong, do not hold the position, do not hold the position, do not hold the position!!! It is better to reverse the position than to hold the position. There are also some statements regarding fees of positive and negative 2% rate.
