This question is very difficult to answer!
First of all, the literal meaning of light position is to follow the trend, which means to use less position to operate smoothly.
If we talk about it in detail, everyone has their own understanding of what is a light position and what is a light position. How many positions are called a light position? Generally speaking, the general public thinks that less than 20% is a light position. Some people think that a light position is a light position. Some people think it is 30%, and some people think that 50% can be regarded as a light position under high general conditions.
Follow the trend, follow the trend of what period. Some people do short-term trading by looking at the 1-minute chart. They may go short on the half-hour chart, and long on the one-minute chart. How to follow the trend requires a specific position.
To sum up, I personally think that if you do not expect huge profits and use stable trading as part-time extra income, you can consider using 20% ??of the position to trade along the half-hour cycle or along the daily line. If the technical foundation is not weak, the return should be much higher than depositing in a bank.
On the other hand, this is a risky investment in itself, and the risks are definitely there. Every effort you make will naturally bring you a return.
Especially in the financial investment world, 95% of people have lost money or made no money. Just imagine that there are only a handful of people who really make money through financial investment.
Ratio-wise, fewer people make money than doing business
