What does it mean to copy stocks and add positions?

Jiacang means that you already own this stock, and then you bought it.

If you fall and add positions, you can spread the cost low, so that you can solve the problem without rising to your original price, provided that you judge that the stock has basically bottomed out, otherwise don't add positions easily.

Novices had better use a simulation software Niu Gubao system to learn the concept of stocks, such as the bidding mechanism of stocks, various terms, operating principles and laws. Although they are of little value in practical operation, they are the foundation. I am willing to help you, and I wish you a happy investment!
