When there is a W bottom in the market, we should pay close attention to it, and once we break through, we will have a chance.

Breakthrough is nothing more than two possibilities, upward breakthrough and downward breakthrough.

If the market breaks through the middle high point at the bottom of W, we must keep an eye on the disk, but it is not appropriate to chase after it immediately (personally, the winning rate is not high). Once the callback is near the Fibonacci point (38%, 50%, 62%) of the breakthrough section, buy decisively, and the stop loss is at the low end of W. If the market is good in the later period, you can take a sedan chair, so don't worry. Constantly adjust the stop loss to the previous low point, and if you are lucky, you will gain a lot.

On the other hand, if you break down, it means that the decline is very strong, and you can short near Fibonacci after the cross-section callback, with a high winning rate. Stop loss is best set at the highest Fibonacci point. Because the stop loss is set at the front height, once misjudged, the loss is relatively large.

In fact, to break through, the most feared thing is a false breakthrough. Using the method I introduced above, you can effectively avoid many wrong breakthroughs. However, experience shows that the reversal pattern after W bottomed out is very strong, and the frequency of the market continuing to break through the decline is actually not very high. The most powerful breakthrough is often rising wedge's breakthrough.

You have to sum up and understand the specific details yourself. Others can only give you a general direction.
