Don't carry the order. Sooner or later, the profit will be returned to the market because of "carrying".

Don't guess the top or the bottom. Sooner or later, the profits from the guess will be returned to the market because of the "guess".

Don't guess at the top or bottom, because it may still be halfway up the mountain.

Don't rely on news, because this is "guessing" the top or bottom.

Don't leave the market easily when you are profitable, because you may end up halfway up the mountain.

Don't get excited when you see the big Yin and Big Yang lines, because it may be someone "performing" it for you.

Don't think that the market trend you see is the last one and be desperate; as long as your principal is still there, there will be market prices every day.

Do not trade frequently. Not only will you lose the general direction and increase the chance of making mistakes, but it will also increase transaction costs, making the gains outweigh the losses.

Don't make counter-trend orders, hold on if you're right, and run away if you're wrong.

Don't buy because the price is low, and don't sell because the price is high. Don't act rashly until the trend changes.

Don't take trading as your main business, and don't watch the market. The time spent watching the market is inversely proportional to profits.

Don't trust other people's opinions unless you are convinced that they are worthy of your trust.
