Technology should be able to make a sustained and stable profit, have the determination to be in the trading market for more than 30 years, have enough talent and sensitivity, and have the ability to analyze and judge. Traders have nothing to do with academic qualifications, and the ability to make money has nothing to do with academic qualifications. In terms of cultivation and understanding, some junior high school graduates are also traders, doing very well. Generally, a city will not have two or three good traders, mainly depending on the success rate, the analysis and control of the disk, and the technical support for the elderly. A good trader must be a trader with stable profits. Judging the quality of a trader can only be measured from the profit, just like measuring whether a farmer is diligent or lazy, mainly from the harvest, except for natural disasters.
