For example, gub, in hindsight, we will find a bottom and draw a vertical center line with this bottom. The bottom on the left has not yet come out completely, and the bottom on the right has come out and been confirmed.

Opening a position on the left is to buy the stock on the left side of this middle line.

The same is true at the top. However, the top is generally used for futures and foreign exchange.

As for whether it is better to open a position on the left or on the right, people have different opinions.
