It's not a good habit to average down, especially for those who are afraid of losses. Once the previous high is reached, the risk will be even greater.

2 Heavy Position do short or Light Position trend are change in market trend strategy, human nature and mentality are actually difficult to change, the real time the brain is online is very short
3 There are very few who can stand up after a loss. The first time I met him, who I have known for almost a year, he almost got liquidated just by placing an order. However, he believes that his losses are less than most, and he is arrogant and refuses to admit his mistakes. Even after specializing in futures contracts for more than 5 years, he still can't come up with any technical ideas.

So it's better not to do contracts, otherwise be prepared for losses. Light Position is not Margin Replenishment, and if there are doubts about Heavy Position, reduce position.
