The role of ground pile

　　The role of ground pile:

　　Formation mechanism: when a variety forms a single pile, there is a small increase, which proves that the energy of the empty side has been partially released, but not completely released, so there is another drop after a small increase, but soon there is a second pile near the previous pile, forming a state of double needle bottom detection, which we call the combination of double piles.

　　Practical application: we can see that after the appearance of double ground stake, we can basically judge that the local bottom has appeared, so as long as we judge the stability of the market trend and the state of sub security, according to the simple long buying rule, we can buy boldly and enjoy the fun of rising the market. From the perspective of form, this combination is easy to become the future stock market.
