Note that in the central oscillation, the safe approach should be to sell first and buy later to form a rhythm. In fact, this problem is very simple. When the chips coming from the low position find that the unilateral trend ends and enters a larger level of oscillation, the sign is the top divergence, which requires reducing the position, and then wait for the oscillation to come down, and then cover the bottom divergence, so that the price difference will come out and the cost can be reduced. If you buy first and sell later, the only possibility is that when it is unilateral, your position is not high, so you choose not to sell the chips and have funds to cover, which is actually a manifestation of the wrong rhythm first.
