No matter what I do, it's wrong. But how can I help you stabilize your earnings?
The market is randomly volatile. Just because you opened a long position doesn't mean the market will go up, and just because you opened a short position doesn't mean the market will go down.
What you need to do is, because the market is going up, you open a long position; because the market is going down, you open a short position. The market does not follow you; you follow the market.
If you haven't gained anything, please leave this industry as soon as possible and don't get trapped in it.
