Step 2: Buy in the callback through indicators or wave patterns.

Method 1. Long-term comparison shows that short-term funds reach below the weak areas and long-term funds are in the strong areas.

Method two. Wave A-B-C falls, in which the daily K-line high point of C is getting lower and lower, and the order is placed above the last K-line high point until it is triggered. The low point of buying the K line is the stop loss.

Method three. MACD's 60-minute line deviates from the bottom and the stock price starts to buy.

These buying points are relative band bottom points, provided that there is an upward trend. Stop loss must be set.
