When you make a profit from trading, don't be overly arrogant,

Don't blame yourself too much when you lose money on your trades.
It is important to understand the principle of "profit and loss". Regardless of whether you are profitable or not, you should summarize yourself from time to time, and ask yourself why this order will be profitable, and why will this order be profitable?
Remember, a teenager, a person with emotions is not a good deal.
