Let's take a look at sol
4-hour line sol is still near the middle track of the falling channel
Go long near the lower track 137-138
This position is the support level of this morning's decline and rebound; it is also the starting point of the isolated high point of the oversold rebound on August 5
When it retraces to this position for the second time, you can try to do a light position (2%-5% position)
Stop loss is placed a little below 136
